I have a 1991 4588 with a bent strut on the port prop shaft. Does anyone know where a replacement strut can be obtained? The boat has been repowered with 370 HP Cummins 6BTA5.9 diesels but the existing prop shaft is 1 1/2 inch which I think is the original shaft size and strut. Thanks.

I think there is a company in NE Puget Sound area that made all the original underwater gear items for Bayliner and still carries them in stock. Can't remember the name but I bought my spare strut from them.

the company that makes most bayliner underwater gear is marine hardware,,they have a place in florida and washington,,the # is 1 800 526 5971,,,do a search for them ,,they may no longer sell to private individuals and you will have to order through your boatyard..

You might first check if a machine shop can press the strut back into shape. I used Vancouver based Dafoe V M Machine Shop - 604-254-4797

I have heard that struts are sometimes purposely bent to bring them into alignment, even from the factory. What you may be observing, may in fact be ok. How does it align with the moter? I think I would suggest talking to someone experienced with alignments on your size of boat and see what their opinion is.

Anyone else heard of this?

Bent? No. Offset to permit the shaft to pass the rudder.

I pulled the boat out of the water due to an increase in vibration. I then removed the shaft and cutless bearing because the shaft was clearly out of alignment with the bearing. Bearing was severly worn at top rear and front bottom. I hoped a realignment of the motor would correct the misalignment in the bearing. I had a local boat mechanic with a laser alignment instrument install a new bearing and attempt a motor alignment to correct the angle of the shaft through the strut. The strut/bearing was so badly out of alignment that the laser beam from the alignment tool missed the hole in the shaft log completely by over an inch. When I had decoupled the shaft flanges at the transmission, the shaft flange sprang away from the transmission flange. The transmission output bearing was under quite a load and is experiencing a slight oil leak. We also took some measurements of the strut and compared it with the same measurements on the starboard side and we had differences of over an inch in some of those measurements. So it is clear the strut is bent. Not to make things worse, water seems to be dripping out from around the strut mounting screws which means, I guess, that whatever bent the strut also shocked the strut fasteners to the hull. Does anyone know if this part of the hull is also balsa coring. It it is this could be a real problem, I think. My plan is to just replace the strut after determining if any damage has been done to the hull and repair that as necessary.

I appreciate all the feedback.

Brian

i think the area where the " V " strut attachs to the hull has a plywood core..you will soon find out as you get into this repair,,,the v type strut will be very hard to bend back to the correct shape,,,there is supoosed to be a casting # on the strut somewhere that will help you when you talk to marine hardware..good luck..doug.
