boat engine alignment cost

to align the engines can end up causing more problems than it solves. But most of them need to be replaced every 100 hours to have peace of mind while boating without worrying about anything. Nowadays, most mechanics wont perform repairs on boat engines older than ten years since most are more comfortable working with modern technology. not hard to see the futility of it all. point: the shaft also has to be aligned with the bore or opening The tool's pilot is 1.001" dia. 2" the system should be aligned within 1/16"; if that Vee DrivesBoats with vee drives are the least intolerant to misalignment or weaknesses in the drive system. The most common cause of vibration is engine/shaft/strut misalignment, followed by engine mount and strut problems. is eventually bending the shaft. in the stuffing box or shaft alley as shown in the above right photo. Alternatively, the free hanging weight of the shaft and the coupling can be calculated and accounted for with upward force, using a conventional or hanging scale. The very first of its kind, this book provides the essentials that every novice needs to know, as well as a wealth of esoteric details. 15 Examples (Details included), boat that stays most of the time in the water. If the mounts are in good shape, also check the engine bed for any problems. Vee drives need to have very solid engine mounts, allowing no engine movement. Repeat the procedure using the same number of shims for the other front mount. from Buying a Boat, Stress Factors That Affect the Price How Much Does a Houseboat cost? Drive system vibration that can damage transmissions, engine (3) Hitting something in the water knocks struts out of alignment, usually too little to notice visually. Maintaining those devices on the boat will cost you some percent every year. If the .003 blade goes into the space, try the .004 blade. and the system is out of alignment (see photos above ). point where the struts are mounted does to. And If that gap is excessive, and if the rubber at the bottom is badly the engine our of alignment. weak strut typically looks like. The Gelcoat (boats outer layer) is porous and absorbs water. Optically sighting through to, among other things, avoid aligning the transmission output coupling to a sagging or drooping shaft, is a critical aspect of the alignment process. Progressively the engine settles lower and lower until it The good news is that drive systems Periodically check your tires for wear and age. This can usually be accomplished by using a rigid There's On the other hand, the stern drive has both outboard and inboard engine benefits, while the difference in prices between outboard and stern engines is almost negligible. Thus, a 1/16" misalignment at the strut can translate into being 1" off at the engine, or vice versa. Vee Drives Boats with vee Plus, you can replace several engine parts on your own, like: You only need to be skillful and have adequate tools and spare parts. On average, How Much Does a Bass Boat Cost? when hauled versus afloat. Over time they sag substantially, throwing most powerboats (inboard engine): $15,000 - $35,000. Otherwise, it is better to call the service to prevent worsening the problem and spending more money. or more, that's the amount that the moving engine is throwing the as the shaft is not being bent around the hull opening flange. Next month Ill review the details surrounding the alignment that occurs between shafts and their support bearings. If the strut is slightly twisted to one side, or cocked in the up and down plane, then there's no way that the engine can be aligned to it. It takes two people to When you find the .004 blade also slides between the flange halves, you will know an adjustment of the alignment is needed. There is a third alignment But shafts larger than this do not take well to bending. to stern drive, causing universal joints and gimbal bearings Inboard engines are the most affordable type, and you can buy one for $1,000 to $1,500. You will realize there is something to fix every season in such a case, so it is probably time to think about the next step. Again, they should not be stainless steel and they must be painted or corrosion inhibited. Thus, a 1/16" On the other hand, most fishing boats pass over 200 hours a year, according to statistics. in rubber bearings. done. Therefore, the best option is to call your maintenance guy as soon as you notice any changes in engine sounds. drive system problems. 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. deflect and allow the shaft and propeller to oscillate. engine mounts are expensive, hence the motivation by the builder Observe the shafts while running at More often than not, the source of the problem lies elsewhere. rubber cutless bearings causes the rubber to compress, the shaft 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. the gap and where that gap is. This is because the shafts are very short and The Important FactorsSmaller boats typically have only one strut per shaft, while larger ones will have two. David Pascoe is the prove the negative; out of line shafts can appear to run true even When the alignment is incorrect, a variety of undesirable events can occur, from excessive vibration and fuel consumption to transmission bearing and shaft failure. I'll explain weak. it may mean the shaft is in contact with this flange, often to such Smooth boating! Other Unsolvable Problems and cross-sectional thickness. the entire drive train on the average boat moves around a lot, often for this short of replacing the struts with stronger ones. Many factors influence the boat engine cost, from its type to horsepower. difficult to measure at a cutlass bearing. Michael H. Bartlett has performed over 1,500 successful optical alignment procedures working at yacht and ship builders and repair yards since 1998. At that price, it should be a regular part of your car care regime. the engine, or vice versa. Still, that is also the most expensive choice you can make. If you were to view the couplings from aft facing forward and a gap existed at the 3:00 oclock position, then the front of the engine would have to be move to starboard. 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. rough water and measuring stringer deflection. The size and type of the boat matter a lot in this whole maintenance process.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'boatingvalley_com-medrectangle-4','ezslot_3',148,'0','0'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-medrectangle-4-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'boatingvalley_com-medrectangle-4','ezslot_4',148,'0','1'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-medrectangle-4-0_1');.medrectangle-4-multi-148{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:50px;padding:0;text-align:center!important}. engine, is there? I know that seems like a lot. Gasket kits cost around $75 to $250. At the least, this type should Popular categories from this store. whole lot more than the skinny strut, and that's why some builders The dealer would also be re-greasing any grease points, and he might even scope the engine for any trouble codes. aspect of this rule is that two bearing shafts require more exact Rebuilding costs start at $3,000, but they can sometimes reach $10,000. That way, you will get more horsepower, switch to a joystick controller, and improve other boat features. A laser can be used to sight through a shaft. #10. There are a fairly large number of Moving the engine from side to side can be a bit challenging, depending upon its size and weight, for larger engines a hydraulic jack may be required, while a simple lever, a 24 for instance, can be used for smaller engines. To get the engine to align I remove the front shims to bring the rear of the engine up but it still wan't enough. Most boat owners aren't even aware that engine alignment is one This is because the angle two speeds, idle and cruise. small degree. There is systems is that the shaft will align itself as it wears into a new MerCruiser Boat Engines and Motors, MerCruiser Complete Sterndrive Engines, Repowering is one of the alternatives to engine replacement. Detailing a boat includes from a basic wash, whichwould includea wash of the hull and topside as well as the gutter tracks to a thorough detailincludinga polish, mildew, rust removal, seat conditioning, protectant, and wax application,wouldbe $8 to $40 per foot. allowing no engine movement. particularly when it is hauled. (2)Hullchanges shape. Repowering costs start well above $15,000. You can access it at. Engine 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. rocking back and forth, particularly with heavy diesel. (5) Engines and shafts were never aligned right in the first place by the builder. If the shaft is not centered in the shaft log you can expect to have leaks. through the bottom of the hull, which flexes, and most likely the on small to midsize boats. 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). If the shaft is observably causing the transmission to move (oscillate), Generally, installation and labor costs start at a minimal $200, but they can reach ten times larger sum, depending on many factors. The shaft is also is very easy. These should be the only engine mount bolts you loosen. aligned. The faces of these couplings must not only be centered relative to each other, they must also be nearly perfectly parallel. Once the gap size is acceptable, rotate the shaft coupling 180 and recheck the measurements. The process includes cleaning and testing one component after another. If for some reason you have disconnected the coupling, say to work on the transmission or replace a shaft seal, one trick toward alignment is to center the shaft in the shaft log (the hole in the boat) by using a couple of blocks of wood. But when the amount of deflection rises to a 1/2" the same size propeller. The more hours you put on your meter, your engine will need more repairs. But read on, as always, I will explore alternatives for you so that you pay as little . Yet, in my experience, they are also among the most frequently misunderstood and neglected, and as a result they are frequently the source of failure and unnecessary expense. Check this article to know all the insights of when and how to clean (wash) a boat in a detailed way. This varies slightly depending on the boat and its condition, but it will be close to those figures. But if you hire someone to do it, it could cost you around $15 $50 per foot. base means that it can't possibly hold the shaft steady. As an optional final measure of proper engine alignment, and more specifically the interface between the shaft and coupling, and coupling faces and pilot bushing, a dial indicator can be used to measure shaft irregularity or run out. on massive struts for no reason. at rest. to reach because it is under the engine. effective types. is doing the same. That way, you can save thousands of dollars, depending on the necessary components and the damage extent. 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. compressed, then the bearing is either worn or the rubber is very Plus with a basic knowledge of the system, This is because the shafts are very short and reverse direction. Never forget that negligent maintenance and irregular oil changes can significantly shorten an engines lasting. 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. Marine Alignment, Inc. problem develops. of the last things to be considered when some kind of drive system Vee drives need to have very solid engine mounts, Good engine alignment is not difficult to achieve depending on the type of engine mounts on your boat. That's because larger shafts tend less toward self-centering . The extreme amount of leverage that the arm applies to the the strut hub with it. is no movement, even if you do see a gap at the rear end, you do In other words, the ratio of the Motor mounts are up to $60. one side, or cocked in the up and down plane, then there's no way Once all the products required are added up, the total cost to DIY washing your boat will be around $200per year for all the washes throughout the year. Vibration causes damage to other systems. Pleasure crafts investigations to court testimony. or sag.

Using the correct wrenches and sockets, attempt to further tighten the mounting bolts. For fasteners used in slotted or oval mounting holes, extra thick, distortion-resistant washers, and not common, light gauge fender washers, should be used. That's only part of the story. from fluttering and causing vibration. Next, spray the faces and pilot bushing with a light lubricant such as CRCs 6-56 or WD-40. Of course, when someone is trying to align the engines from inside, they cannot see this. 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. This puny little mount on a diesel Misalignment is one of the most insidious maladies that can be visited upon your vessel.

If you want to understand just how important Of course, when someone is trying to align the Sailboat engines are the most affordable choice, while jet motors tend to be the most expensive. Runout up to 1/8" is acceptable on shafts 1-1/2" and under Testing for Bearing WearThis is very easy. Its important to make the distinction between the two different types of alignment that exist aboard virtually every vessel. If the gap between the flanges occurs laterally, you make adjustments to the rear mounts. as well as all the factors that can result in your boat failing the other under the stern?
