if you ever started a car with a bad starter bindex on the starter it will turn over a little then kick out and stop turning the flywheel. Well this new starter on my boat is doing the same thing. As soon as one Cylinder fires the bendex on the starter kicks out, it take many cranks on the starter to get the motor started. On a car it is a wore out bendix or bad flywheel. On my boat the flywheel teeth all look good and this is a brand new starter.
My local boat shop where I purchased the starter says it is not the new starter, but could offer up anything else for me to look for.
As soon as the motor tries to start, the bendix on the starter kicks out ( not making contact with flywheel.
