Have Boat Questions? Ask a Boat Repair Expert.
Hi Bob, my name is***** read what you wrote. Are you running this engine off of a plastic portable tank or a tank that is built into the boat? Do you have a vacuum gauge and a T fitting?
Are you near the outboard now for a test?
I'm sorry I don't understand you. You doubt what is the problem, I haven't had you test anything yet.
Okay... Well you said it "acts like it runs out of gas", all I wanted to do was actually test that. But if you are confident that it is not running out of gas the next step is to check the spark. Do you have a timing light?
You could have spark on one cylinder but not the other.
Do you want to duplicate the problem and get back to me or what would you like to do?
Okay let me know how you make out
