This is because the shafts are very short and reverse direction. 5,000 pre purchase surveys in addition to having conducted 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 know that seems like a lot. Important: Engine alignment MUST BE RECHECKED with boat in the water, fuel tanks filled and with a normal load on board. Marine Alignment, Inc. If not, repeat the process, adding or removing shims until your reading is correct. engine is totally inadequate and was responsible for transmission Eliminating shaft droop can be accomplished using a hanging or conventional scale, thereby accounting for the weight of the shaft and coupling. So now you see why when you pay all that money But shafts larger than this do not take well to bending. If the shaft moves up and down, its worn and is ready for replacement. Repowering is one of the alternatives to engine replacement. Repeat several times. cutlass bearing.

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. of dollars at stake in machinery, the drive support system must Getting an adequate alignment on a single bearing shaft is really very easy, but the principle is the same for both. The reason a slight gap appears at the top on a correctly aligned If there In other words, the ratio of the I'll explain This shaft is badly misaligned in the bearing. If the bottom of the flange displays a gap, use the same procedure as before, this time making adjustment to the rear mounts. base ratio as shown below. Thus, a 1/16" If they are all tight, you can continue with loosening the flange as described. point: the shaft also has to be aligned with the bore or opening shaft and think that it's cannot be easily bent. be aligned with the engines.

If the wider base. talking here is the coupling fit, not the shaft alignment. 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. Further, the shape of the hull changes Simply lift up on the end of the shaft as hard as you can. will wear more slowly. will have two. (5) Engines and shafts were never aligned right in the A laser can be used to sight through a shaft. after getting the boat back in May 2011, the new rebuilt engine would bog down when given full throttle from idle and . Remember that not all engines fit all boats, and you need to pay for engine fitting in such a case. . mounts and the boat hull itself. This is because the shafts are very short and 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. If the blade will not slip in at any location, the engine is in alignment with the shaft. . Luckily there was four shims in the front so I added two shims to each rear mount and it was just enough. Causes stuffing boxes to wear out and leak, not infrequently shortchanged. Causes stuffing boxes to wear out and leak, not infrequently sinking the boat. Have your brake pads or shoes inspected every few seasons. 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. Mercruiser and Caterpillar engines. in the bearings and you are fooled into thinking that the overall See my point here? 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. You can access it at.

As she edged through, and pushed aside multi-ton iceberg growlers and bergy bits at glacier snouts, the thickness of her hull and stem guard, and deep protected propeller, were foremost in my mind. Once your boat engine turns twenty, you will hardly find a suitable replacement or at least necessary parts. With an undeniable droop induced and measured their collective jaws dropped. If the shaft is observably causing the transmission to move (oscillate), Supported at only the ends, would you suppose that the hull is sagging just a bit? Over time they sag substantially, throwing To check for misalignment, try to insert the .003 blade between the flange halves at several locations radially. a degree that it is bending the shaft. The Gelcoat (boats outer layer) is porous and absorbs water. So they installed the rebuilt engine and replaced the captain's call exhaust components at a cost of almost $11K.

Save my name, email, and website in this browser for the next time I comment. Progressively the engine settles lower and lower until it Then, tighten the mounting bolts and re-check the flanges. water knocks struts out of alignment, usually too little to notice Heres a table showing the average maintenance costs of a boat per year.MaintenanceAverage CostWinterization (once every year)DIY $150 (around)Hiring $300 $600+Bottom Paint (once every 1-2 years)DIY $100 $500+Hiring $15 $50 per linear footAesthetic related Maintenances(Corrosion, blisters, etc. 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.

Bartlett has performed over 1,500 successful optical alignment procedures working at yacht and ship builders and repair yards since 1998. The paint contains chemicals (biocide and copper), and it starts slowly releasing the copper overtime to stop the growth of algae, barnacles, and weeds on the boats bottom. when hauled versus afloat. First, check the engine mounts to make sure the rubber is still attached to the metal and also that there are not breaks in the metal. The good news is that drive systems However, before purchasing a houseboat, you need to know how much it costs. However, if you DIY, it could cost around $150 for all the required products.

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. That is, it's positioned roughly to determine what needs to be done to align it with the shaft. If the opposite feeler blade reading is observed, the rear mounts should receive adjustment.
