Thanks all. Yes, I was trying to jump across the 2 big lugs, and would get a whir out of the starter, but it would not engage. I looked again, and could not identify the other connection...the starter is facing away from my access panel, behind the alternator, and just hard to see. I will have to get an inspection mirror and see if i can see where to connect.
I am hauling out next Saturday, and implored my old boat partner to give me a hand with the haulout, so I have an extra pair of hands to start the engine while I keep the pink pop antifreeze sucking into the system.
But I will figure this out eventually !
