I have not got to test the motor in water yet (fixing a bad carb) but when I had my 1987 9.9 running I noticed the prop would spin while in nuteral. Now when I put it into forward or reverse ther was no clunk sound but it seemed positive and the prop would really spin fast then. Is it normal for the prop to spin slowly in nuteral while out of the water and using muffs? Also should I be hearing that clunk sound while putting into forward and reverse? It just seems to have a positive click but that is about it.
