Was in storage so first I cleand bottom carb, tried in lake and was fine for 5min. After that it runs with little power. What it does is you can put around lake at 5-12mph. If you give it full throttle it bogs and dies. Today I cleaned bottom carb again and it was great for 2 minutes then same thing. Then I cleaned all carbs, and it still bi gs and dies. Whats wrong with the stupid thing, need it going in a day for our family reunion, but if I can't get it going by then I still need it to be going for the summer. Anyone had the same problem???

Inlines surely do have their issues. When you cleaned the carb it probably got out of sync or the float level is too low or high. make damned sure the float level is right . Link and sync the carbs, check the timing.

The idle mixtures need to be a bit rich to allow acceleration.
