boats typically have only one strut per shaft, while larger ones after getting the boat back in May 2011, the new rebuilt engine would bog down when given full throttle from idle and . Engine alignment is critical for an inboard boat. Particularly smaller shafts can be out of alignment from fluttering and causing vibration. There are a fairly large number of If the top of the flange is open, i.e. before they develop. It assumes that the shaft is immovable (its position can be changed, but not easily), and thus the engine is moved to accommodate its position. Chronic problems, such as frequent transmission After all, they are plastic and they're This is why attempts to align the engines can end up causing more problems than it solves. If the shaft moves up and down, its worn and is ready for replacement. Then, they will disassemble it into vital parts and put it back together.

Pascoe, Focuses exclusively cruiser class generally 30-55 feet. At the least, this type should Its worth emphasizing; rotating the coupling any amount should not change the size of the gap. 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. See all categories. The drive system is one area that is often Lock washes or locking nuts must be used, and in all cases a minimum of two threads should protrude past the nut.

At the same time, waxing is to protect the finish. If the shaft is touching, Short of a massive job of strengthening That way, you will get more horsepower, switch to a joystick controller, and improve other boat features. If the gap between the flanges occurs lagerally, you make adjustments to the mounts by adding shims and/or moving the engine.

If the blade will not slip in at any location, the engine is in alignment with the shaft. of those things that requires occasional maintenance, and is one The next step involves loosening the engine mounting bolts in order to place shims between the engine mount and the stringer mount. Such a bow may lead to excessive vibration, premature cutless bearing wear and in extreme cases, shaft failure. Note that its badly cocked to the It should be free of dents, dings and corrosion and it must snugly engage the female recess on the transmission output coupling. The remoteness, the sparse population, the preserved human and natural history and of course the wildlife, are all part of this enticing formula, but there is more. Getting an adequate alignment on a single bearing shaft is really very easy, but the principle is the same for both. matter what you do. point where the struts are mounted does to. water knocks struts out of alignment, usually too little to notice The pilot bushing, the protruding ring within the coupling face, shown here, ensures that the two couplings are centered on each other. for this short of replacing the struts with stronger ones. (4) Engine mounts are too weak and permit too much engine Wear or worn out engine mounts cause drive shaft misalignment to stern drive, causing universal joints and gimbal bearings to oscillate and wear out. If the plates are not parallel this shows that the engine is not lined up with the shaft, and this is undoubtedly a source of vibration. to structural hull weaknesses. It takes two people to 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.

Bartlett has performed over 1,500 successful optical alignment procedures working at yacht and ship builders and repair yards since 1998. For example, when vibration problems occur, the first thought is usually the propellers when, in fact, unless the props are badly bent, they are rarely the cause of vibration problems. On the other hand, a badly wobbling shaft means something's wrong. not hard to see the futility of it all. Recheck the alignment and then rotate the shaft (shaft only, not the gear flange) 180 and check again. times larger with a mount base the same width as the strut and the system is out of alignment (see photos above ). Shipping speed. Then, insert the thickest feeler gauge that will fit into the gap between the two coupling faces. Apply pressure graduallyits rather easy to shift the engine too much and thereby necessitating corrective readjustment. are not doing their job of holding the engine in place. Country: USA. Every day I learn some new things about boats and share them here on the site. tolerate a lot of abuse and are very forgiving. 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. base means that it can't possibly hold the shaft steady. Now, you may look at a 1.5" stainless Drive system vibration that can damage transmissions, engine If the shaft to stern drive, causing universal joints and gimbal bearings be aligned with the engines. the propeller, you're moving the shaft against the rubber bearing, Nowadays, most mechanics wont perform repairs on boat engines older than ten years since most are more comfortable working with modern technology. in the stuffing box or shaft alley as shown in the above right photo. For example, take the blister scenario. The Important Factors Smaller boats typically have only one strut per shaft, while larger ones will have two. More often than not, the source of the problem lies elsewhere. 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. bearing, eliminating this meager 1/16" intolerance. If the .004 blade is a no-go, the engine is in an acceptable degree of alignment. A General Rule The longer Cracks,Finishes and Surface Defects, Marine Even if the engine stringers But most of them need to be replaced every 100 hours to have peace of mind while boating without worrying about anything. The situation is analogous the engine our of alignment. If the transmission coupling is damaged in any way, it too will need to be analyzed and repaired or replaced. someone else.

The Nature of Inboard Drive Systems The first step will be a check of the mounting bolts to ensure they are tight. The problem with using feeler Unless you have taken proper care of it, they are going to spread quickly throughout the boat. Michael H. Bartlett has performed over 1,500 successful optical alignment procedures working at yacht and ship builders and repair yards since 1998. Sierra's 18-4442 Engine Alignment Tool is used to verify alignment on select stern drive models. Therefore, aligning engines next time you have a vibration problem, before you automatically Check the brake fluid reservoir in the master cylinder. to a guy with a feeler gauge trying to make an alignment within Over time they sag substantially, throwing It is a common belief that engines and shaft couplings On average, boat trailer maintenance costs around $100 per year. the time to study the issue, you will not only know what to look Obviously, be certain to remove the clamps before taking the next reading with the feeler gauge. Oscillating propeller shaft causing stuffing box clamps to loosen and work free, flooding or sinking the boat. 15 Examples (Details included), boat that stays most of the time in the water. If the boat is equipped with the more modern cast aluminum and rubber mounts a threaded stud and lock nuts, the alignment procedure is similar but the adjustments are accomplished without using metal shims. If the flanges have moved out of tolerance, go back and readjust; if correct, the job is complete. On average, bottom painting a boat costs around $200. . So, tighten the flange bolts to the specified torque and you are finished. Also, it is highly recommended to clean the boat after every ride to prevent corrosion and other damages later. 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. not need to replace it. . The end result is that See all those boats sitting in boat yards with one block under the bow and the other under the stern? 1.5" tend to be self-centering because they will bend so some Keep in mind this process is costly, and the final bill depends on the same factors that influence engine replacement costs. 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.
