I purchased a FourWinns with an OMC 3.0 Cobra/Volvo Penta stern drive;
Plate from the stern drive: (engine has no id plate)
Prod No. 3868029
Type: <blank>
Ratio: 1.85
Seriel: T0783719

I am having serious trouble locating parts. This boat went underwater by the stern. I've refurbished the engine and have a bellows kit ready to install. What I am missing is a bellows for the shifter cable. Everything I've found so far shows a bellows in the drive, which is not the case here. There is a hole at the transom where the cable goes through, but nothing stopping water from entering; and when I did a quick test at the dock last year, water was pissing from the sheave on the cable inside the boat. I also cannot find any impeller parts for the drive (im assuming it has one, i'm not sure).

Any help would be greatly appreciated.

It’s a 1994 from what I can tell. I’ve done some more research here, and I gather the sheave on the throttle cable is what keeps the water out. Unfortunately, mine leaks. I can get it to stop by moving the cable around however... could this be a quick fix? Getting to the end of the hose to unthread it from the transom is.. well it looks like a huge pain. Thanks again for any insight you might have.

Looking for help to find where the trim relays are located on a Volvo Penta 3L 2005, GLP-C engins SX drive. There's noise when I trim it up, bit nothing when trimming down so presuming the relay & can't find ot on the maintenance manual. Waiting for a trim switch to replace, bit not certain it's the root cause. Any help from my northern brothers or southern neighbor woild be appreciated.
