Leak from around TRS housing into boat.
 

Put the boat in from lift this summer and noticed water leaking into engime comp. from around the the drive/gimble in one spot. Does the engine have to come out to fix this? I see the cork gasket on the outside, how do I replace it? Tried search but no ggod.

Thanks,

It's probably the driveshaft bellow. The rubber boot you can see when the drive is trimmed up while looking into the outer transom assembly. The boots are rubber, get old, and crack. You do not need to remove engine to replace.

It could also be the pivot pin seal.

I will check. The bellow is only two years old and the last time it broke, the u joint gave up the ghost. The boat, being a TRS not Bravo, did not leak as the transmission seals against the back. The leak in the inside is from the outside of the inside housing.

There is a cork gasket between the housing and transom. But I've seen more leaks due to flexing/rotted transoms than failed gaskets.

tr/trs gimbal leak
 

The tr/trs suffers from a minor design flaw. At the bottom of the gimbal housing, the actual horizontal bearing surface for the gasket is extremely narrow. The gasket extands quite a bit above the bearing surface.....creating a "pocket", if any fluid is in the bilge, it inevitably fills the "pocket", which in turn eventually penetrates the cork. Put into conjunction the fact that the vast majority of "load" is against the lower bearing surface and the realization will come to mind that they will "all" develop a leak eventually.
The "cure" is simple. upon implementing repairs, simply put a bead of Boatlife Lifecaulk (polysulfide thiocol) on "both" sides of the cork, which creates a virtual torque dampener. Lifecaulk remains pliable and pretty much cures the inherent faulty design.
No need to pull the engine; but thats another chapter.
