One more "MINOR" problem found

[FastOlson]

Rubber parts and Time

The shaft log, as usually referred to, is the frp tube that the shaft passes thru from outside to inside. The shaft should not contact it. Problem is that as the mounts age, the engine settles down lower and at some point the shaft can start rubbing against the inside of the frp tube.

The rear mounts take the most weight and, while, in theory, spec'd out for that load, can still collapse at some point.
Four years ago we decided to R&R all our mounts on our '88 model boat with about 2000 hours. No oil or water leaks around the engine and all looked fine.

When we got the two rear mounts out (interesting struggle...) we found that both sides were collapsed down to metal-on-metal.
That explained why we had observed the shaft sitting a little "low" as it entered the boat from the tube where the PSS bellows is clamped on. Our shaft did not abrade the inside of the tube, but was within a smidgen of doing so.

If you get a lot of years (15+) and hours of use (1500+) on that diesel, replace those mounts and check out the whole alignment situation.

what yard are you using?

Lake Catherine Marine

Chuck,
Have the boat over at Lake Catherine Marine. Really like it over there. Is a small yard, kinda junky, caters mostly to shrimpers and oyster boats. But the owner is very knowledgable, and has lots of good advice. Besides, the rates are better than others in the area.

how do you get there? i would like a place to haul out and do some stuff this winter. price reasonable?

Lake Catherine Marine

Chuck,
Lake Catherine Marine is off Hwy. 90. You go under the hwy. 90 bridge, and hang a hard right soon as you pass Ft. Pike. Stay on the far right side of the channel going in. It's about a mile and a half up that channel on the right hand side. Kloudie1 came over the other day, met Ronnie, the owner, and is going to bring his boat over there later on this fall to do a bottom job. He is much more reasonable on prices than Maritime Systems, which as far as I know is the only other place on the north shore with a travel lift. Recently heard that Seabrook does not allow DIY, so the choices are getting more and more limited. Drop me a PM and I can give you better directions and a phone # if you want.
