Mercruiser - why wont it stay running?
Help! I bought a 1974 mericruiser 4cyl. inboard boat and it runs great until you are on the water for about thirty minutes. It then starts cutting out and eventually wont start. we have to get towed back to shore. It has new wires, plugs, points, and oil change. Seems like it is when there is a load on the motor it bogs out . could this be a head gasket problem? Thanks in advance for any advice!
