I recently bought a used 2000 Mercury 115 horse and the owner said he had two props for it. One was the original and the other was a specialty prop that he bought for towing people for skiing but he really didn't like using it because it raised the rpms too high and he didn't like going over 4,000 rpms (I think he said 4,000rpm).
Well, I chipped the 1st prop and am sending it in for repair and because of that I put the other prop on. I haven't gotten it to full throttle yet but at 3/4 it runs about 3,500-4,000 rpm. I thought this would be fine. I checked the max rpm on the side of the motor and it says 5,250rpm.
So, I'd think I could open it up to full and probably be under 5,250rpm, probably closer to 5,000. Is that bad though? Should I be way under the 5,250rpm mark? He seemed really concerned about not using it at full throttle.
