Been reading these forums for a few days and got some mixed feelings on some of my problems. I have a 1986 GT150 on a hydra sport. When I bought the boat of coarse the guy said it ran good. Well finally got it out and couldn't got more than 24 mph out of it and every time you stop you have to reprime and hurry up and restart it before it loses prime. Long story short got it home and found cracked gas lines. Replaced all lines and primer ball. Checked pickup tube and was fine. opened carbs up and blew through all jets with compressed air. Took it out again and samething. nothing more than 24mph not sure on rpms tac don't work. got it home and checked compression. 91-92-91 on starter side the other side had 100-99-100 from what I read it's with in specs. Put new plugs in since had them out. Took carbs off again looked a little closer at them but seem fine. not sure if it makes a difference or not but I'm preety sure I got them right but might have carb 1 and 3 switched around. Don't think so though. Now looked at fuel pump (VRO was compltely removed by somebody else) diaphram was questionable. possiable leakes by screw holes. and some of the plastic seems to be cracked. took my fuel pump off my 50hp force that I know was good. took it out again and now your lucky to go 5 to 10mph and thats if i keep reaching back and priming the bulb. I could be wrong but I thought any vacuum ran pump would work. I guess I was wrong. Any ideas what I can try or do.
