Had a factory lower unit installed. After 20 hours I changed the gear lube. I did put a couple extra pumps in with the vent bolt in in case I lost some fluid putting the lower in. Some fluid came from prop exhaust. Ran great for 2 hours the I got fuel added stabil as usual. Smoked a little on start. Then ran great for 15 minutes then within a few seconds lost power went to 3500 rpms from 5600. Ran like that for 10 minutes to dock. Went to idle and died. Swam it in. Wouldn’t restart. Found thick gray grease with bits of plastic or metal in prop. It did start when I’d be in neutral and full throttle choke but when going back to idle die. Smoked some so didn’t try again.
