    Still not Completly happy w/prop..

    I have a 90 Bayliner Br1800 powered by a 85 115hp Johnson. The prop I am currently using is 13.75x15 Turning point Hustler. It pushes my boat at around 33mph at 5600rpm. Which is ok for me. I chose this prop because of the wanted faster holeshot and pulling power. I love it other than the...

    O-ring on top of Driveshaft?

    I have a '85 115hp and trying to put a new l.u. on. My manual says the driveshaft should have a o-ring right below the splines. My old one didn't have on and neither did the one I'm putting on. So should I go buy a o-ring to put on it, or is it needed?

    90 hp timing

    I was wondering if my '90 90 hp should be at tdc at idle. I thought I read in another thread that it was, but now I can't find that thread. The reason is that I set my timing at 30 btdc, then checked it at idle and it was about an inch before the mark. So it would be between the 32 and the...
