I give up, I'm gonna break down a buy the factory service manual for my $1000 boat. I must be getting older (wiser). I attempted a pressure test on my stringer 400. Lower would not hold pressure at all. Intermediate held better but leaked and saw bubbles coming from the top cover of housing. Then I remembered I should have sealed off shift cable. While performing an inverted reverse headstand I used a mirror to get a look at the end of that shift cable. Lifted the two spring load hook things with teeth and tried to give the cable a little tug. It didn't seem like it wanted to come out and felt like there was a spring behind it, so I quit there. The old me would have started blindly tearing the cable housing down til I could see how that thing is put together. Instead I'm stopping until I get the manual. I'm sure this drive has few hours on it and I want to be careful not to tear it up. My question is if I didn't seal that shift cable when pressure testing would I get false results for the intermediate, lower or for both?
