I have a 3.0 L and recently changed the engine. The new engine had a 14" flywheel. After installed I needed to buy a different starter. This was a smaller starter. I have an assit solenoid and wired exactly the same with the yellow and red jumper on the starter. When wired with a jumper the small starter bendix does not retract right away. The old starter (bigger one) when wired this way does not have a problem. I got another small starter and it did the same thing. I took the starter to a starter shop and they also did not know why the smaller starter continue to stay engaged after starting and the big starter does not(same result when bench tested). When the jumper is not used the problem does not exist. Is it because the bigger starter has a bigger spring in the bendix and can overcome the residule current energizing the solenoid? }

My Guess is,.......

You got it Wired Wrong............"

"I tried shimming no difference. The condition is the same when bench tested. I checked the wiring in the maintenance manual, it is correct. I pulled the engine out of the boat and installed the 12 3/4" flywheel (original one) and reinstalled the big starter (original starter) and there is no more problem. Like I said, the problem was also reproduced on the bench test. I was hoping there would be a simple fix so I would not have to pull the engine. Thanks for responding. I just don't have an answer and either did the mechanic at the starter shop."
