I would add that the understanding if your shaft is spinning as it should, or if your gear is "slipping" when in reverse, is key here. You mentioned earlier that it seems to accelerate when you ramp up the rpm.
- Can you confirm that you keep the same ration "rpm engine" / "rpm shaft" when you hold the shift handle at "idle rpm", and at "higher rpm"? This could be checked with a cheap Harbor F**** speed gun ( I did that to tune the idle speed on mine), depending on the accessibility in your boat of course
- if it is slipping, all the items mentioned by the others on shift cable / gear adjustment apply.
- if it is not slipping, you are back to you prop... first question: how clean is it? after comes the choice of the prop, and I am useless on that
