    older carburetated mercruiser 5.7 hard start

    i remembered while i was using my multimeter to test for 12v while cranking. the only way i would get a reading is. with the red probe on the positive on the coil and the black probe on a bolt on the engine. not on the coil. shouldnt i get 12v probing the positive and negative of the coil.

    older carburetated mercruiser 5.7 hard start

    That is not what i wanted to hear, but its better than being fully attached to the starter. It will not be fun to get to it. The engine compartment is tight. Hopefully its not bad

    Alternator questions

    the engine that has the bad alternator has the power steering pump. I guess in the spring I will have to chase wires on both engines and se which engine is doing what.

    Alternator questions

    I have dual mercruiser 260's on my new to me boat. Do both engines normally have an alternator on them. I think one is bad just wondering if 1 alternator is enough to charge the batteries. Never had dual engines before so this is all new to me.
