Last weekend I replaced the plugs and a fuel line that was leaking to my bottom carb. Took the boat out tonite and ran fine for a while but started to sputter, motor came back to life once I primed the fuel bulb. Checked the replaced fuel line but no leaking there. While I was in the motor I did reset the choke lines to fit into the rubber boot properly. Could I have possibly messed up the choke?? Any help would be appreciated.

Doesn't have a choke, has a primer to shoot fuel into the carbs for cold start. It isn't getting gas if you had to pump the bulb, change the fuel filter lately???

found ANOTHER leak coming from the fuel tank into the motor, hopefully it's the last one and this fixes the problem
