My quick question is; Does anyone, preferably with the same engine and sterndrive, have experience with the exhaust tube? Good? Bad? Pros and Cons?
Here is my situation;
My engine is a 2001 5.0L MerCruiser with an Alpha I Gen II Sterndrive. A freind and I recently replaced the gimbal bearing, u-joint bellows and exhaust bellows. The exhaust bellows was like torture to reattach to the bell housing, but we got it all the way on the flange with the bellows adhesive and then tightened up the hose clamp. After taking it out 3 times we noticed that the exhaust bellows was slipping off from the bell housing.
We removed it from the bell housing side and cleaned all surfaces with laquer thinner. Then we replaced the thin inadequate looking hose clamp that came with the bellows and got the same type that was used for the original exhaust bellows. Using a heat gun we warmed up the bellows and stretched it out good, making sure not pull the other end from the transom side. After some considerable stretching we heated up the end and put some bellows adhesive on the flange and the bellows and reattached it. Tightend up the hose clamp real good and it was back on looking great.
After a day of letting the boat sit in the yard we took it out 3 days in a row and checked the exhaust hose and it looked good. After sitting in the yard for 4 days, with the sterndrive trimmed up in trailer position, I noticed last night that the exhaust bellows had detached itself.
At this point we are contemplating removing the bellows completely and stretching this thing as far as it will go and holding it there with clamps for a few days or even a week. Out of the package this bellows is real compact and doesn't want to stay stretched. I even talked with a local mercruiser mechanic and he said that the clamp that comes with it is not good enough, and it's tough to get the bellows to stay attached.
My questions:
Has anyone had this problem before?
Anyone have any suggestions for getting this thing to stay attached?
At this point I'm considering an Exhaust tube, like this one http://www.iboats.com/Mallory_Tube_...st tube--**********.861905228--view_id.364109
Is there a danger that the water will rush back into the exhaust manifold, when going from a plane to sudden stop, and cause problems if I use this tube?
