So i am new to the boating scene, but i have a problem. I acquired the boat a year ago free of charge but not so free. I started off putting a new prop on it, rebuilding the carbs, and new wires, new fuel line, to list the least. Motor runs fine out of the water and ok in the water until i open it up at Wot. Once it is at wide open throttle I get the speed but every now and then. But when it gets up in speed it sounds like it wants to go some more but hesitates and never continues to give me full power. Then it just loses power and backs down maybe 20 mph or more at times. then i have to back off the throttle so it doesn't totally bog down and cut off on me. Then i can give it more throttle and im back up to speed for about two minutes and the same thing happens all over again. Its a never ending cycle every time I'm on the water. Im getting great spark on all cylinders. Now im at my wits end because ive done everything i think it could possibly be from spark to fuel. Help me out here. I just want a good summer with the kids towing the inflatable without stalls. And getting to my fishing spots without the delay.
