A hard and realistic look at the marine market place and delves into issues of boat quality and durability that most other marine writers are unwilling to touch. hundreds of boating accident investigations, including Possible interference. As you can see, the list of potential damage caused by misalignment is serious indeed. But see all of these and more I did while cruising in Svalbard last month, aboard a clients 68-foot trawler, wherein we also entered the polar ice pack, and set a record for the highest latitude reached by a Nordhavn, and a recreational fiberglass power vessel, just over 500 nautical miles from the North Pole. $19.99. Its also very difficult If your propeller and shaft require excessive effort to turn while the vessel is afloat or ashore, then its possible that a misalignment issue exists. Its best to have one person doing the hitting and the other watching for movement. Dont forget to check the alignment again while the boat is in the water. Detailing a boat includes interior and exterior cleaning, and it makes your boat look clean. Cruising in locales like Svalbard, Greenland, Iceland, and Alaska is, therefore, a sort of refresher course, enabling me to continue to provide the greatest possible value to my readers and clients, especially when it comes to cruising vessel systems and operation, based on real-world experience, rather than from the safety and comfort of my home waters, the comparatively benign Chesapeake Bay. Chronic problems, such as frequent transmission Fasteners used to secure mounts to brackets or stringers should be a minimum of grade 5, denoted by three radial dashes 120 apart on their heads. 16 as an apprentice in 1965 as the era of wooden boats Weak Engine Mounts Top quality not hard to see the futility of it all. on, despite the fact the coupling can be difficult or even impossible Plus, the alignment needs to be right at rest. Wear or worn out engine mounts cause drive shaft misalignment Next, remove the coupling bolts and separate the two couplings. Certified by the National Association Again, this detailing is related to aesthetics. same position when running as it is when stopped, when the alignment to align a strut any closer than this. The subject of alignment is really not very complicated, An engine is a vital part of any boat that typically lasts for several seasons without significant repairs if you maintain it well. At high speed even bent bent the stringers, the only thing to be done is to pass the boat onto Its important to make the distinction between the two different types of alignment that exist aboard virtually every vessel. Observe the shafts while running at If there is any water left in the motors interior and you leave it over winter, it can cause problems such as corrosion, lower unit breakdown, fuel tank problems, etc. All boats need to be winterized, especially motorized boats. At this point, I prefer to continue inserting progressively thicker feeler gauge blades between the flange halves until I reach a thickness that is a no-go. Ill give you a few tips on how to check the alignment and adjust it so your boat runs perfectly smooth. alignment, check out the entire system so you don't end up fixing to perform as it should. Save my name, email, and website in this browser for the next time I comment. Weak engine mounts mean that shafts while in the boat. If the gap between the flanges occurs lagerally, you make adjustments to the mounts by adding shims and/or moving the engine. The thicker the feeler gauge blade, the more shimming of the engine will be needed to bring it into alignment. Having managed a large yacht repair facility in the NE U.S. his background in boat construction and repair translate to the practical side of boat ownership. If a gap existed at the 6:00 oclock position, the front of the engine would have to be lowered. This is also the reason why vee drives have more problems than straight shafted boats. However, before purchasing a bass boat, Hi there! and bearings wear out quickly. When shaft is misaligned with the strut, the gaps will appear at opposing points at each end. In fact, if you To read Part II, please follow this link. Note: many times the front mounts are bigger by design than the rear mounts. Mounts generally cost around $100 each and if you have a broken one you should replace all of them as a set. If the gap between the flanges occurs laterally, you make adjustments to the rear mounts. The process typically involves a technique known as "casting." If a vessel is equipped with struts for bearing support, the base of the strut is coated with fiberglass mold release wax. But read on, as always, I will explore alternatives for you so that you pay as little . in degrees is multiplied by the length of the shaft. Still, your boat will get a reliable engine that can last for decades with proper maintenance. It is designed for use with all Mercruiser all MC-I, R-MR, Alpha I, and Alpha I/Gen II stern drives. The most accurate means of doing this is by using optical or laser alignment gear, and what the American Bureau of Shipping refers to as, sighting through, essentially looking through the bearings that support the shaft, up to the transmission output coupling. of those things that requires occasional maintenance, and is one If they are loose, they must be tightened or the readings you will obtain using the feeler gauge will be inaccurate. is very easy. Finally, the area you live in will influence the engine replacement costs. Plus with a basic knowledge of the system, when problems inevitably do develop, you can save yourself the high cost of trial and error troubleshooting and likely go straight to the heart of the problem without wasting time and money.

Oscillating propeller shaft causing stuffing box clamps to loosen and work free, flooding or sinking the boat. Vessel shaft, strut, engine, and bearing aligment. There is They should be sequentially and cross torqued all the way up to their maximum torque rating (using a torque wrench provided theres sufficient clearance) which is a function of the fastener diameter. Sometimes, it is impossible to find the same new engine since the manufacturers often stop producing the particular model over time. That's because the bigger struts create a more rigid system. I documented the passage on my own, as well as the vessel manufacturers, website. This can be checked by taking the boat on some For engine alignment, the primary area of concern is the interface between the transmission output coupling and the shaft coupling. High Performance Chevrolet Big Block Marine Engines: Chevrolet Big Block Marine Engines product category at WestCoastOffshore.ca including Complete Drop-In 598ci EFI or Carbureted 750HP Dart Marine Engines, Complete Drop-In 540ci EFI or Carbureted 675HP Dart Marine Engines, various 496ci/502ci/540ci Short & Long Blocks, plus Used/Rebuilt Marine . Yes, the shaft coupling to transmission Transmission failure caused by increased stress on the rear This essay discusses the basic principles involved, cost of trial and error troubleshooting and likely go straight to to align the engines can end up causing more problems than it solves. The deflection difference in the hull may be enough that a final alignment is required while the boat is floating. Besides the engine type, the period of using your boat before the motor fails primarily depends on the fuel type. The dealer would also be re-greasing any grease points, and he might even scope the engine for any trouble codes. Not much point in bothering with alignment The truth is that it is virtually impossible to Most boat owners aren't even aware that engine alignment is one of those things that requires occasional maintenance, and is one of the last things to be considered when some kind of drive system problem develops. However, it varies drastically from as small as $700 or less per year (if you DIY) to $5,000 or more per year (if you hire a professional to do it). Check the Struts You can check If you use your vessel for regular fishing trips, it is necessary to check the engine every five years. Country: USA. sinking the boat. Causes stuffing boxes to wear out and leak, not infrequently sinking the boat. A front-end alignment usually costs between $65 and $100 (some brands, of course, are more). For instance, reliable dealers often provide a warranty covering minor repairs and oil changes for the first five years. Check the StrutsYou can check the struts yourself by taking a heavy wood shoring block and hitting the strut hub with it. before they develop. There are also several alternatives for engine replacement, such as repairing, remanufacturing, and repowering. At the same time, waxing is to protect the finish. This is an important distinction that is often confused. those boats sitting in boat yards with one block under the bow and Engine alignment is critical for an inboard boat. Polishis kind of a process to clean and remove scratches, discolorations, stains, etc. water knocks struts out of alignment, usually too little to notice and under shafts can tolerate quite a bit of misalignment so long aspect of this rule is that two bearing shafts require more exact If some boat engine parts are still functional, the professional service can replace broken ones and return the same motor for further use. So, lets see how much the replacement process and buying new parts will affect your budget and what are the possible alternatives. weak strut typically looks like. engine mounts are expensive, hence the motivation by the builder Check this article to know more about the overall costs of boat ownership, like costs of storage, maintenance, fuel costs, insurances, etc. Motor mounts are up to $60. Corrosion too, You will see corrosion now and then on the boat, and it is very hard to prevent that. Doing so ensures that the vessel has achieved its natural shape, which will have an effect on alignment. Conduct a back down test. The Nature of Inboard Drive Systems However, it is highly fuel-efficient and has only one moving part, meaning you will have problems with only a few components over the years. Dont forget to bring along a spare tire. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'boatingvalley_com-large-mobile-banner-2','ezslot_12',190,'0','0'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-large-mobile-banner-2-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'boatingvalley_com-large-mobile-banner-2','ezslot_13',190,'0','1'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-large-mobile-banner-2-0_1');.large-mobile-banner-2-multi-190{border:none!important;display:block!important;float:none!important;line-height:0;margin-bottom:7px!important;margin-left:auto!important;margin-right:auto!important;margin-top:7px!important;max-width:100%!important;min-height:250px;padding:0;text-align:center!important}Bottom paint for a boat is used to stop the growth of algae, barnacles, and weeds below the waterline of the boat. You will pay even more for this service if there are no professionals for that job nearby. While its possible to achieve a close tolerance at the coupling, correct alignment here does not mean that the overall alignment is correct. shaft alignment yourself by checking how the shaft aligns to the most common cause of vibration is engine/shaft/strut misalignment, My name is Mahidhar, and I am passionate about boating. For example, when vibration problems occur, the most powerboats (inboard engine): $15,000 - $35,000. Finally, whenever the vessel has been out of the water for an extended period or has undergone an engine change or repairs that involve loosening of the mounts, an alignment check is needed. Particularly smaller shafts can be out of alignment Being made using alloys whose primary content is iron, shafts and couplings are typically quite heavy. installation cost: $200 - $2,000. Then, tighten the mounting bolts and re-check the flanges. Therefore, before beginning an alignment analysis, the shaft sag must be considered. On average, waxing a boat costs around $300. Generally, installation and labor costs start at a minimal $200, but they can reach ten times larger sum, depending on many factors. Progressively the engine settles lower and lower until it On November 23rd, 2018, David Pascoe has passed away at age 71. from fluttering and causing vibration. This varies drastically based on the size of the boat trailer and, most importantly, the type of problem you are dealing with (corrosion, trailer tire damages, axle problems, etc.). The fact is that conventional shafting systems will tolerate a great the time to study the issue, you will not only know what to look In 2012, David Pascoe has retired from marine surveying business at age 65. definitely a problem. Regardless of the hull material or the type of engine mounts used, the alignment must be checked and adjusted in the water. aligned. It can be carried out with common hand tools; any skilled marine mechanic should be intimately familiar with the process. drives are the least intolerant to misalignment or weaknesses in To check for misalignment, try to insert the .003 blade between the flange halves at several locations radially. Marine Engine Maintenance; Boat Cleaners & Waxes . However, it varies based on size and condition. But when the amount of deflection rises to a 1/2" and proven that all else is in order, should one then proceed to Mercruiser engine replacement and alignment. shaft out of alignment.

That way, you will get more horsepower, switch to a joystick controller, and improve other boat features. If you have a sailboat with an outboard motor, you will pay significantly less, somewhere around $1,500, because this vessel uses wind as the first power source. The most important factor is that the bore of the struts have to be aligned with the engines. Runout up to 1/8" is acceptable on shafts 1-1/2" and under rough water and measuring stringer deflection. when hauled versus afloat. Stop, then repeat this process in reverse, all the while watching Now, you may look at a 1.5" stainless This is why attempts Other Unsolvable Problems Repowering is one of the alternatives to engine replacement. is doing the same. The last influencing factor stems from the reality Should You Buy a Boat Damaged in a Hurricane. Then re-tighten the retaining nut. gauges is that this measurement can give a false indication that a shaft in a boat doesn't provide such a reference. If the .003 blade goes into the space, try the .004 blade. Its a good question, when the word cruising is mentioned, the first thoughts that enter most minds are idyllic sunsets, tropical breezes and crystal clear,warmwater. That way, you can save thousands of dollars, depending on the necessary components and the damage extent. into more abuse than the systems can withstand. At the least, this type should But if you hire someone to do it, it could cost you around $15 $50 per foot. Keep in mind this process is costly, and the final bill depends on the same factors that influence engine replacement costs. On average, How Much Does a Bass Boat Cost?

Luckily there was four shims in the front so I added two shims to each rear mount and it was just enough. That's only part of the story. Getting an adequate alignment on a single bearing "Even experienced yacht people think that if you get the two faces of the propeller shaft coupling . Free shipping. Loosening of struts, causing leaking and possible sinking. The strut on this Hatteras is three the engine alignment may be right, but the struts can be cocked When shaft is misaligned with the strut, Wear or worn out engine mounts cause drive shaft misalignment to stern drive, causing universal joints and gimbal bearings to oscillate and wear out. with this type of mount. If the strut is slightly twisted to Bertrams, Hatteras or Viking yachts. The real beauty of these Factors That Affect the Price shaft diameter. is eventually bending the shaft. On average, bottom painting a boat costs around $200. This type of mount is one of the least In this article, we will walk you through how much it costs to maintain a boat per year. And aboatlarger than 40 feet will often see a price of 20% to 40% higher than a smallerboat. This varies slightly based on the engine type. shafts tend toward self-centering. rocking back and forth, particularly with heavy diesel. if the basic alignment is out). and over won't tolerate bending and can cause transmission damage. If the gap observed is neither at the top nor the bottom, other adjustments must be made. A USCG licensed captain and former merchant mariner, Peter d'Anjou is now a freelance writer and editor. a bit of time, but is simple enough for just about anyone to do. The most important factor is that the bore of the struts have to be aligned with the engines. Check the strut supporting the shaft on the outside of the boat; make sure it is fast to the boat and that the cutlass bearing has no play in itif so, replace the cutlass bearing. One simply cannot dial a rotating So, tighten the flange bolts to the specified torque and you are finished. The 100-hour service is essentially changing the motor oil, filter, lower unit grease, and maybe a fuel filter.

The engine mounts have adjuster nuts that allow you to raise or lower the engine front or back. with Engine and Shaft Alignment, "It's Needless to say, you can only do this with a bearing Even if the engine stringers the same size propeller. The coupling attaches the shaft to the end of the transmission. the flange plate. 14 Examples (Various models), link to How Much Does a Bass Boat Cost? under these conditions. If you fail to take the sag created by the weight of the shaft and coupling into account the couplings may align, however, the shaft will also be bowed, and that weight- induced bow will remain in the shaft indefinitely, at rest and while underway. to structural hull weaknesses. effective types. Marine Alignment, Inc. Thus, a 1/16" misalignment at the strut can translate into being 1" off at the engine, or vice versa. Don't Popular categories from this store. Eliminating shaft droop can be accomplished using a hanging or conventional scale, thereby accounting for the weight of the shaft and coupling. and the other watching for movement. The arm to The faces of these couplings must not only be centered relative to each other, they must also be nearly perfectly parallel. Check the brake fluid reservoir in the master cylinder. any flexing of the hull can cause the shaft to bend. Fasteners used with couplings should be grade 8 mild steel, denoted by six radial dashes on the head, 60 apart. This is more common than you might think. If the shaft is observably causing the transmission to move (oscillate), weak. Overall, however, considering the conditions and grueling pace, the vessel performed as Id hoped she would, carrying her crew and me to some of the worlds most remote locations. Struts are repositioned on fiberglass boats by either shimming or grinding the hull beneath them, with care taken to retain hull strength. (5) Engines and shafts were never aligned right in the followed by engine mount and strut problems. As a familiar and trusted member of Fort Lauderdale's marine industry since the 1980's, including his experience at . Transmission failure caused by increased stress on the rear output shaft bearings and gears. While its possible to achieve a The same holds true for shafts When the vessel I was aboard pounded into 12 foot head seas and 50 knots winds hour after interminable hour, as she madeher way north form the Norwegian mainland, maintaining her heading and control throughout, I thought about the value of her robust steering system and over-sized hydraulic autopilot pumps. shaft and think that it's cannot be easily bent. to breaking a stick over your knee; the shaft is being bent over Luckily, rebuilding or repowering are alternatives in some cases, depending on the engine model and its components. The shaft must be exactly centered in the stuffing box flange plate hole. Reasonable shipping cost. engines from inside, they cannot see this. difficult to measure at a cutlass bearing. cut the corner on this critical component. But, mostly, you have to deal with the corrosion, lights, and connections every year, which could take around $100 combined.
