Hello everybody,
After some leaking in the boat through the bellows,I pulled out the sterndrive unit and i found the rubber gasket of the bell housing cut and next to the gimbal bearing(mercruiser A1 1978). When i tightened the bearing retainer about two and a half threads were left out of the sterndrives' "neck".My dealer who took a look at it told me that the problem wasn't caused by the left threads but because of bad handling during pushing the sterndrive in. Although I had put some sealer at the base of the rubber gasket to ensure that it will remain right at the bell housing the bad thing happened.How can i avoid now this to happen again? Should the edges of the neck and the retainer meet each other?(i mean the retainer is all in so the rubber steps to both edges)In my unit this seems impossible.During the tests the sterndrive worked well .PLEASE HELP

Since the bell hsg. has been full of water start by greasing the u/jouints and gimbel brg. The dealer is telling you the truth about the seal ring, so use care when reinstalling the unit. Some glue them, I never have, it help reinstalling them if when you remove it you block under the unit, so when installing it's at the right height without picking it up.

What Laddies said......;)
Bellows adhesive will hold it in place, though I don't use it either.....
Having the skeg sitting on something when removing the drive helps immensely.....;)

Thanks for replying,
something i didn't tell you is that i tightened the retainer not by using the proper wrench but with the "traditional way"(hammer and, i don't know its name).It was tightened good but afterwards i noticed that the wounded edges that i didn't take care to smooth them may caught the gasket.Is it better instead putting the gasket to its place inside the bell housing and after leading the sterndrive in than putting the gasket to the edge of the neck and then leading the sterndrive in?

For the future....
If the skeg is sitting level on the ground (or whatever) when it is removed, it will make lining up & reinstalling the drive much easier......;)
