I'm the poor slob who had problems with boat after getting it from
shop 2 weeks ago. Took boat back..had oil injection disabled, brought
it home today. 84 Yamaha 115 hp outboard

I started it up in the driveway to test it with muffs on. boat started
fine. I engaged the free idle lever to test it because that was one
of the things that it was in the shop for. It seemed to work. I
barely revved the engine, probably never exceeded 2000 rpm. Motor
seemed to be running fine, as I was closing the free idle lever it
sounded sort of like it was going into gear and the motor stalled.
Motor was idling for less than 5 minutes total.

Tried to start the motor back and just got a loud click from the
starter. I did have problems with the starter a few weeks ago with
the clutch not pushing the gear up onto the flywheel. Now the gear is
meshed with the flywheel but is not turning it at all. Battery is
charged, connections at terminal seem okay.

I shifted the motor into gear and tried to turn the propeller by hand.
Not sure if I should be able to or not, but I was not able to turn it.

Boat is going back tomorrow...for the 4th freaking time. I'm scared
my powerhead is seized. Am wondering now if the service tech added
oil to my gas and ran it through before disabling the oil injection.
Tech said he added enough oil to err on the side of caution based on
what was estimated in the tank. While the engine was running in the
driveway, it was emitting lots of smoke with that lovely 2 stroke
smell.

If I was just having starter troubles, I don't see why the motor would
have just quit like it did. If the starter goes bad, does it put a
load on the engine to the point where it will stall if it's idling?
