a pressure test sounds like a good idea to me. while i'm not familiar with your genII drive, i'd think that some of the same possible issues could apply to your drive along with mine. who knows, might be something as simple as 2 drain/vent plug seals being in place. sometimes the seal can get stuck on the drive, ya replace with a new seal and then ya got two and a leak. bellows go bad, letting water intrusion into that area, many times ruining the ft. seal of the drive. fishing line wrapped around the prop from what i understand can ruin the seal. i'm sure there's others too. but ya get the idea. might be something ya can deal with, w/o having to reseal the whole drive...I guess I'll just pressure test and go from there. I just wanted to re-seal on general principle instead of finding a leak here and then next year maybe another seal goes bad.
