I was flushing the cooling system to put water in and I noticed a knock/rattle when I held it about 1500 rpm after holding it there for a couple minutes she locked and stalled. When I checked it this morning it turned both ways only so far then locks up. I had another 350 on the stand so we swapped it. I will look into it when I find time but plan on keeping it because it is a 4 bolt main motor.
