  • Motor issue

    After finding and fixing the tranny leak I now have a motor issue. I was driving the boat all weekend and was fine pulling wake boarders, then on the way home I opened it up then it almost died then kicked back in the died again then I throttled down and putted in. On the way back tried to give it gas and it died. Got it going again and babyed it home. any ideas?

    Fuel filter, fuel pump, carb. Sounds like it is now starving for gas. Look at one thing at a time.

      Also check the caps that cover the vacuum ports on the carb and the vacuum lines (I believe your boat has two vacuum lines). I had the same thing happen to me and one of the caps that covered a vacuum port was missing.

        Ok thanks guys I will check I thought it might be a gas issue. Was a bit scared that I blew it but it did run on the way in. As im new to this boat and im not sure where the vacum line would be?

          It sounds similar to a problem I had last year which ended up being the fuel line from the tank to the fuel pump was soften by the ethanol in the gasoline. The softer hose would be sucked closed by the fuel pump as the engine rpm went up. Easy and cheap fix to replace the fuel line and they make new fuel line that is ethanol resistant.

            That is what i need to do is put a new fuel line and I have ran some ethanol gas in it. It was just like when I gave it more gas it lost power and died?

              I would start with the fuel line because it is cheap and easy. I spent $14 on fuel line.

                  If you smell gas when it's running it's prob your carb flooding out, but ethanol gas will ruin old rubber fast.

                    My boat did sit for 4 years before I got it going and I didnt change the gas line so im hoping that is the issue, as I did run ethonal gas in it.

                      I work on a ton of small engines (lawn mowers, trimmers, etc.) you should see what ethanol gas does to plastic carbs. I have seen some that are melted. After you get it fixed find a gas station that sells ethanol free premium.
