I took my family out scalloping,Saturday boat ran great on the way out,on the way back at 3 quarter throttle motor shut down,would not start back up,Starter was working fine at this time.pulled plugs pumped gas ball up.Cranked up after about 30 minutes of trying to figure out what was going on.Motor ran great for 10 more minutes and shut down again, Now Starter motor cranked very slow,like the battery was low,tried to wiggle the battery cables thinking there was a bad connection,when I grab the negative wire it was super hot.hit the switch to the other fresh battery and still cranked slow.had to get towed in.When I got home,I cleaned the battery terminals,put the ears on the motor, and it It cranked good while I was checking to see if I had any spark.which I didn't.Then the starter ,started cranking very slow again,grab the negative and it was very hot again.So I removed the starter.The starter was so hot I had to put a couple of rages around it to pull it off . Brought the starter to auto store to see if it was bad,which it was ,So now I'm waiting on my new starter to get here.My question is what gives the coils power to spark,And could it have something to do with why the negative and starter was so hot.Very possible I burnt starter up trying to get it started.Just trying to figure out were to start once I get my new starter.Any Information would be much appreciated. {1991 Mercury 90 HP 3 cylinder}
