As others have stated, the recommended oil mix ratio for this engine is 24:1. It is for good reason on these engines.
You say that it revs properly in neutral and in gear on the hose, does it rev properly in neutral on the boat? If it does, I’m really beginning to suspect the shock absorber in the gearcase. Definitely eliminate the easy stuff first, but I find these broken or sprung quite often. If the motor appears to have average to above average hours on it I usually weld them and change the drive pin to brass as part of the tune up service. Unless you need to get into the gearcase anyway though, save that for after all the other things have been checked out. If everything else checks out and it is down to the shock absorber, fix that immediately. Running with a dragging shock absorber damages the bearing carrier for the drive shaft and it will eventually destroy itself.
