So my boyfriend bought a boat which came with a 1967 Evinrude Angler motor. It needed some work which wasnt a problem. He cleaned the carb inside Nd out, replaced the fuel pump and the coils. After replacing the coils which we assumed was the reason it wouldnt stay running... But it only ran for about 10 minutes and died and wouldnt stay running again. Hes also checked and its getting fuel and the spark plugs are working fine.
