I have a 2002 non turbo aquatrax that is giving me a hard time. It wouldn't start so I went through and tested and cleaned all connections starting with the connection directly off the start switch. I put everything back together and it fired right up. A few trips out and a no start again! I replaced the starter solenoid and it fired right up. Once again, a few trips out on the lake and no start once again. Anyone have any suggestions as to common bad spots to check?
