Hi,
when starting my motor its a
rum. . . . . rum . . . . rum . . . . rum. . . . . then rum, rum rum and fire or start. The battery is good and a marine battery, I think 750 cold cranking. With cowling off some smoking can be seen at starter connection at the rum. rum. Once it has run it starts right up but this is concerning to me. Can someone tell me what is going on. I fog my cylinders before storage.
thanks in advance for any information.
James

I'm definitely not an electrical expert, quite the opposite actually, but the smoke is not a good sign. I would check for corrosion and/or looseness in the connections at the starter. If the starter is good and the battery is good, it should rum,rum,rum immediately.
Also, what kind of engine? There are some guys here who have tons of knowledge about specific brands and models.

Thanks for the reply, I will def check connections. I have a 69 Nauset with 1985 115 Johnson motor. That was my concern maybe corrosion in cylinders?

If you have smoke than there is heat and the part that's getting hot will expand making a tighter conection so the motor gets all the juice and it turns over as normal,,Clean and dry tight connections are best,,If all that checks out look for a crack at one of the wire terminals,,It might all be inside damage

How old are the battery cables? Put the cable to your ear and gently bend the cable back and forth. If you hear crinkling noises, consider replacing the cables. Bob

Really sounds like a loose connection to me. Remove, clean and reinstall the cables to the starter and make sure they are tight. I think that will solve your problem.
Bad battery cable wouldn't get better as you cranked or after the motor ran. What you have said so far really sounds like a loose connection that expands as it heats up and makes better contact.

Can be all the above, bad connection, wires bad, and bad battery, bad starter. My battery cables are bigger (thicker) than then need be, carries the current easier and does not over heat the starter. If you are running a Mercury for some reason if th battery is not tip top, you will have a problem starting the engine. Bad connection speaks for itself. Hope its not the starter this would be the last thing I check... I relly think you problem is a bad connection/wire...good luck to you
