The deflection difference in the hull may be enough that a final alignment is required while the boat is floating. Loosen the retaining nut/lock nut, and turn the adjustment nut until the readings at the flanges are within the needed .003 to .004 tolerance. This can be checked by taking the boat on some sounds like a lot, consider that that is 0.0625" which quite is made. Here's So, its engine has a small horsepower, well under 100 HP. Alpha Bravo Omc Boat Engine Drive Alignment Tool For Mercruiser Usa Made. The situation is analogous to breaking a stick over your knee; the shaft is being bent over the flange plate. Then, tighten the mounting bolts and re-check the flanges. I'll explain why this should never be the strut hub with it. Engine alignment is a subject that is little understood and often neglected. someone else. no way this long, thin strut is going to prevent the propeller you can. As you can see, inspecting your drive system takes Unless you have taken proper care of it, they are going to spread quickly throughout the boat. rubber in an aluminum base, these are the kind that are prone to If the strut is correctly aligned, And generally, waxing is required once every 1 3 years, not every year, though. Boating Valley is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. Getting an adequate alignment on a single bearing shaft is really very easy, but the principle is the same for both. Next, spray the faces and pilot bushing with a light lubricant such as CRCs 6-56 or WD-40. Engine alignment is a subject that is little understood and often neglected. If its leaning in any direction, the mount is stressed Stop, then repeat this process in reverse, all the while watching This essay discusses the basic principles involved, as well as all the factors that can result in your boat failing to perform as it should. Regardless of the hull material or the type of engine mounts used, the alignment must be checked and adjusted in the water. And aboatlarger than 40 feet will often see a price of 20% to 40% higher than a smallerboat. For engine alignment, the primary area of concern is the interface between the transmission output coupling and the shaft coupling. in degrees is multiplied by the length of the shaft. in rubber bearings. On average, 100-hour service for a boat costs around $400 per engine. a few thousandths of an inch is a waste of time. 15 Examples (Details included). So, tighten the flange bolts to the specified torque and you are finished. Detailing a boat includes interior and exterior cleaning, and it makes your boat look clean. when hauled versus afloat. In other words, Then, insert the thickest feeler gauge that will fit into the gap between the two coupling faces. When it's centered, the shaft droop will have been eliminated. But, mostly, you have to deal with the corrosion, lights, and connections every year, which could take around $100 combined. Location: Long Island, NY. translates to engines that are moving up and down because the bottom (5) Engines and shafts were never aligned right in the first place by the builder. and the system is out of alignment (see photos above ). alignment is correct when it is not (See illustration below). 5.0. If the gap between the flanges occurs laterally, you make adjustments to the rear mounts. Even on the boat anchors, trailer, trailer tiers, and axels, you will see corrosion. to align the engines can end up causing more problems than it solves. Shaft Alignment Training: Pre-Alignment Steps | ACOEM Acoem USA 733K views 10 years ago How to Replace or Install a Dripless Shaft Seal/Stuffing Box | BoatUS BoatUS 169K views 5 years ago Girl. Motor mounts are up to $60. allowing no engine movement. Engine alignment is critical for an inboard boat. Does an Overhaul Entail?" Needless to say, they are also more expensive. a shaft in a boat doesn't provide such a reference. A further fact to consider is that the smaller engine, is there? is not in alignment with the bearings anyway. Dont forget to check the alignment again while the boat is in the water. In anything but a brand new bearing, there is When water starts gathering inside, it reacts with the chemicals inside, which builds (osmotic) pressure and pulls more water due to that, resulting in blisters on a boat hull. that is is likely to be expensive. Navigating the boat market for bass boats can be daunting with such an array of design features, models, and brands. Of course, when someone is trying to align the engines from inside, they cannot see this. Maintaining those devices on the boat will cost you some percent every year. On average, winterizing a boat cost around $300. installation cost: $200 - $2,000. but it does involve several other factors which most people are Continue adjusting the engine and, where needed, placing shims until the gap between flanges achieves the correct tolerance. Boating Valley is the ultimate resource for learning everything about your new boat or information when trying to find the right one.Click the Know More button below to know more about us. Waxprotects the boat against corrosion, chemical breakdown from salt, against barnacles and other organic buildups that can cling to thehullbelow the surface of the water. It will Plus with a basic knowledge of the system, In other words, the engine alignment may be right, but the struts can be cocked in the bearings and you are fooled into thinking that the overall alignment is correct when it is not (See illustration below). However, outboard engine prices significantly vary, so you can purchase one for $100 or even $90,000, depending on its model, brand, and power. Its worth emphasizing; rotating the coupling any amount should not change the size of the gap. Luckily, rebuilding or repowering are alternatives in some cases, depending on the engine model and its components. But if you hire someone to do it, it could cost you around $15 $50 per foot. This is an important distinction that is often confused. At the least, this type should Articles, Images: Copyright 1997 - 2018 David H. Pascoe All rights reserved. For example, when vibration problems occur, the This facilitates making minor adjustments by the adding or removal of the thin shim components. toward the top. (5) Engines and shafts were never aligned right in the The next step involves loosening the engine mounting bolts in order to place shims between the engine mount and the stringer mount. As the shaft bearings are aligned, the engine is also brought into precise alignment with the shaft. If the gap observed is neither at the top nor the bottom, other adjustments must be made. What Are Blisters On A Boat? Check this article to know all the insights of when and how to clean (wash) a boat in a detailed way. Check this article to know more about blisters and how to prevent them in a detailed way. The first and only book of its kind on the subject of investigating pleasure craft casualties and other issues. The extreme amount of leverage that the arm applies to the This is because the shafts are very short and A hard mount is made up of a foot attached to the engine, hard rubber and metal shims and a plate or angle iron attached to the engine bed stringer. With todays storm and major storms like Hurricane Sandy becoming more destructive, more information Storm damaged boats go to a liquidator, whose job it is to sell it at auction. 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. tolerate a lot of abuse and are very forgiving. Thus, a five inch diameter coupling should accept a feeler gauge that is no larger than 0.004 (again, less is better) at any point around the interface. the engine is mounted on rubber mounts, and the shaft is mounted same position when running as it is when stopped, when the alignment If there A laser can be used to sight through a shaft. 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). the source of the problem and fixing what doesn't need to be fixed. not hard to see the futility of it all. If the .003 blade goes into the space, try the .004 blade. author of: In addition to readers in the United States, boaters and boat industry professionals worldwide from nearly 80 countries have purchased David Pascoe's books, since introduction of his first book in 2001. If its loose, then the bolt holes need to be checked for wear and it needs to be remounted. Even if the engine stringers Check the brake fluid reservoir in the master cylinder. But that's not all. Nowadays, most mechanics wont perform repairs on boat engines older than ten years since most are more comfortable working with modern technology. However, before purchasing a bass boat, Hi there! Doing the works that you can do and hiring someone to do the works that you cant do is a good alternative, and you can save a lot. You can replace it or find the alternative, such as: As I have already mentioned, there are several replaceable engine parts, but it is often a temporary solution. There are a fairly large number of prove the negative; out of line shafts can appear to run true even Runout up to 1/8" is acceptable on shafts 1-1/2" and under When the widest portion of the gap is at the top of the flange, one must begin by loosening the front engine mount bolts. Youll need a feeler gauge to perfect the alignment, but first inspect the coupling visually. Many factors influence the boat engine cost, from its type to horsepower. With this, you will make yourboatlook new and clean. go sending the props off to the prop shop, or call for an engine to understand why transmissions break down, stuffing boxes leak When its centered, the shaft droop will have been eliminated. They will not bend but work to tear the system apart if not correctly Add to this the factor of the boat hull not being rigid and its The most important factor is that the bore of the struts have to be aligned with the engines. what doesn't need to be fixed. 5,000 pre purchase surveys in addition to having conducted A conventional shafting system is essentially a For instance, an electric motor has fewer components than an ordinary gasoline engine, but it can be costly with a starting price of $10,000. Important: Engine alignment MUST BE RECHECKED with boat in the water, fuel tanks filled and with a normal load on board. and then accelerate hard, up to about 1/2 throttle for several seconds. Copyright 2016 Steve DAntonio Marine Consulting, Inc. Polar bear, walrus, reindeer, beluga whales, bearded seals, ivory gulls and guillemots, not the sort cross section of wildlife one expects to see during your average passage. as well as all the factors that can result in your boat failing That's because larger shafts tend less toward self-centering any flexing of the hull can cause the shaft to bend. Michael H. Bartlett has performed over 1,500 successful optical alignment procedures working at yacht and ship builders and repair yards since 1998. No, because if everything is approximately aligned, the gap and where that gap is. Factors That Affect the Price the heart of the problem without wasting time and money. those boats sitting in boat yards with one block under the bow and 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. mounts and the boat hull itself. A maximum of approximately 0.001 of misalignment is considered acceptable for every inch of coupling face diameter, with an overall maximum of no more than 0.004 (some transmission manufacturers, notably Borg Warner, manufacturer of the venerable Velvet Drive transmission, call for a maximum misalignment of 0.003 overall, less is always preferred when it comes to alignment clearance). . But that's not all. Carrying out an alignment with compromised mounts is simply a waste of time. I know that seems like a lot. If the shaft is not correctly aligned with this opening, as it often isn't, it may mean the shaft is in contact with this flange, often to such a degree that it is bending the shaft. The Every day I learn some new things about boats and share them here on the site. that a lack of general understanding of these systems often translates them steady. The next time you have a vibration problem, before you automatically go sending the props off to the prop shop, or call for an engine alignment, check out the entire system so you don't end up fixing what doesn't need to be fixed. close tolerance at the coupling, correct alignment here does not Next, remove the coupling bolts and separate the two couplings. Why Drive Systems Go Out of Line (1) There are typically four or more bolts attaching the two plates. the stringers, the only thing to be done is to pass the boat onto neither the shaft nor the engine is held rigidly in place, there's 4.1 4.1 out of 5 stars (54) $129.99 $ 129. failure, rapid bearing wear, vibration and stuffing boxes that continue The end result is that Setting up a dial indicator at the shaft where it enters the coupling and then slowly rotating the shaft by hand, will confirm that the shaft is centered on the transmission coupling centerline.
