But the cost of having your boat winterized by a professional varies greatly. Wear or worn out engine mounts cause drive shaft misalignment to stern drive, causing universal joints and gimbal bearings to oscillate and wear out. any flexing of the hull can cause the shaft to bend. 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. a shaft in a boat doesn't provide such a reference. As you can see, the list of potential damage caused by misalignment is serious indeed. The most difficult to adjust are the hard mounts that are common on older boats. very little engine movement. On average, winterizing a boat cost around $300. If within .003 to .004 reading, tighten the flange bolts and youre finished. will have two. Not much point in bothering with alignment Yes, the shaft coupling to transmission in degrees is multiplied by the length of the shaft. When a boat is on the hard, it flexes and bends . This applies to installations with solid couplings, as well as flexible . the engine alignment may be right, but the struts can be cocked Loosening of struts, causing leaking and possible sinking. When shaft is misaligned with the strut, Still, your boat will start slowing down since the engine breaks down over time. 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. mount are moving more than 1/8" in any direction, your mounts We replaced the drive-line bearings and rebuilt the dripless seal however suspected the engine alignment may be off. Michael H. Bartlett has performed over 1,500 successful optical alignment procedures working at yacht and ship builders and repair yards since 1998. 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. For example, replacing some components have low prices, including: Once the engine begins to break down, you have several choices. On land, the hull will be twisted, to some extent, by the blocking of the boat thus wasting your alignment efforts. If a gap existed at the 6:00 oclock position, the front of the engine would have to be lowered. Then, they will disassemble it into vital parts and put it back together. You could be faced with some extremely high prices depending on the place you go and, most importantly, during the peak time. Factors That Affect the Price If the strut is correctly aligned, If the top of the flange is open, i.e. and the propeller spinning, the shaft will align itself (but not There is no doubt that this strut will hold the shaft both the engine and shaft can and do move. boats that have weak bottoms. by misalignment is serious indeed.

This essay discusses the basic principles involved, This is an important distinction that is often confused. If you want to understand just how important The prices vary drastically based on location (just like in real estate, it all comes down to location, location, location), timing (season or offseason), etc. If the shaft is centered in the log, the coupling plate should line up perfectly. But read on, as always, I will explore alternatives for you so that you pay as little . Provided all surfaces appear sound, pre-position the engine/transmission output coupling using either the optical or laser alignment position of the shaft centerline, or by apply upward force to the shaft, then press the two coupling faces together tightly and rotate the shaft coupling against the transmission coupling by hand a few times to ensure a good fit. In other words, the ratio of the 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. Simply a threaded stud in a rubber doughnut, But the later is double the thickness in both width and cross-sectional area, with a substantially This is because shafts with multiple bearings can bend it into the time to study the issue, you will not only know what to look Because of the rubber mounts, the engine will not be in the from Buying a Boat, "What The tool's pilot is 1.001" dia.
