Hello all, Had a bit of a grinding sound the last few weeks on the starboard engine. Had a feeling it was a bad gimbal bearing. Was ready to replace today and pulled the drive. Noticed the bellows was full of muddy like liquid. So now I know why the gimbal bearing went bad.... Also, while pulling the boat out of the water, lots of corrosion all around the drive. Had to replace all the trim cylinders. So how did the water get in there? The bellows look ok, no cracking that I can see. Last spring, I had the marina pull both drives and they saw NO water in the bellows but the u joints were rusted. Did they not seal the drive correctly? What I really dont understand is there is NO gasket between the drive and the bellows. So how does it keep the water out and not seeping in through the drive and the bell housing??? Can water be coming from the drive???
