my motor has no power but runs fine
Can your help me?? I have a 1990 omc cobra 4.3 v6 and it seems to run fine but has no power. I dont hear any unusual motor noise, but the local marina says that I may have blown a head gasket except I do not see any signs of water in my oil. Is this true? because sometimes I am skeptical of what local marinas say. I can only go idle speed even when I give it full throttle, can you help?
