    I/O (Sterndrive) Conversion to Outboards

    These are direct injected i would assume. since the timing of injection inhibits detonation they can use really high compression ratios again. Always a lot of discussions on compression on the muscle forums I am on. One of the engine builders mentioned difference between 9.5 and 11:1...

    runny/liquid grease in bellows?

    That doesn’t look like enough to be gear lube. Grease and gear lube smell different. Pressure test the drive see if inout shaft is leaking but that looks like a fairly typical separation of the oil from the grease . Would not worr6 about what I see there. did you gear lube bottle loose level?
