Re: [Cal_Boats] Engine Shaft Alignment (Joe)

Joe, I had this bad vibration in my engine that went away (or at least is way better) after I aligned the engine. It was off about .014 and now passes a .003 test. The engine is solid bolted to the boat and solid bolted to the shaft. It is a Gray Marine Four-112. Is there a vibration reduction gizmo I should know about? Allen

Hi Allen - You may have a vibration reduction by installing an R&D flexible coupler. This will compensate for .010" misalignment. It also dampens torsional vibrations , and acts as a "fuse" in your drive train. That is, should the prop become fouled from a lobster pot, seaweed, etc, it will sacrifice itself and save your expensive drive train. You will be able to limp home under reduced power. These couplers are standard with all Beta Marine diesel engines, and they work very well. *Joe DeMers - owner* Sound Marine Diesel LLC SoundMarineDiesel.com <http://www.soundmarinediesel.com/> *phone & fax (860) 666-2184* On 2/11/2011 1:02 PM, Allen Edwards wrote: > > > Joe, > > I had this bad vibration in my engine that went away (or at least is > way better) after I aligned the engine.
