Rafinx Posted July 28, 2011 Author Share Posted July 28, 2011 (edited) ARGH this is driving me crazy, you both have valid faults, And ive just left my boat for the day, I will be going back tomorrow. I checked the carby butterflies they are clean as a whistle, could not believe how clean it was. Im also thinking of checking if I have oil fouled the spark plugs, I use a 25:1 oil/fuel ratio. But next couple things to check are mentioned above, will continue investigating and informing you guys, thanks again.

Rafinx Posted July 30, 2011 Author Share Posted July 30, 2011 (edited) OK well I took the boat out again yesterday and the whole time it did not want to get on the plane, which has led me to believe the carby main jet is blocked, allowing for slow idle speeds but no power when needed.

Rafinx Posted July 31, 2011 Author Share Posted July 31, 2011 why are you do use 25-1 fuel mix it should be 50-1, yeah I found that out a couple days ago, some bloke told me to do it. So Ive readjusted it just on 50:1. Link to comment Share on other sites More sharing options...
Rafinx Posted August 1, 2011 Author Share Posted August 1, 2011 Just resolved it. The valve in the fuel tank was shut, it must of rattled itself that way, quick twist and a few minutes later the engine went flying again. It explains why it would happen after awhile, because it would create a vacuum in the fuel tank. But I think I can explain the reason for last trip to not have any throttle, I accidently touched an adjustment that was meant to let the butterfly open completely, so it would not let me go past a certain speed. So anyways long hard yards are now done, it starts first go, and flies like a rocket, thanks for every one's help in helping me try to diagnose this issue.
