Hey folks, hoping for a touch of guidance.
Two Saturdays ago, ran a bout a third of a can in seafoam in a full tank of gas. Motor was running fine. Later in the day it would spit and sputter at rpms under 3000, over that it ran fine. Finished the day without issue.
This past weekend, dropped the boat in engine would not start. Bendix pops up but doesn't spin flywheel. Starter is a year old. Through a booster pack on, same thing. Hmmmm....
Try and turn flywheel by hand..nope, doesn't want to move. Remove belt, still doesn't want to turn. I had some issues with this flywheel (worn teeth) hand a machinist buddy of mine rebuild it earlier in the year, hasn't been a problem.
With the belts off, I did manage to turn the flywheel backwards about half a turn. Try and start it again, Bendix engages spins flywheel, then flywheel locks again.
So what am I possibly looking at here? Would like to do some of my own trouble shooting before taking it to a shop.
Pull plugs and see if I can spin it?
Drop lower unit and try and spin it?
Would crap wrapped in the prop cause this?
Any guidance is much appreciated.
