still around 52 4800 on the gps with my 93-sr 271 502 MPI bravo 1 22" LH. I believe it's a 1.5 my serial starts with 0F04. Found a place to open it up. Delaware River. Still running on last year's gas almost full tank one passenger and full water tank. funny I always thought it was a 23 prop. looks like I have a couple very small dings, size of a pencil point. Is that enough to throw it off? It will take a full weekend to run out about 90 gallons.

64mph with 7 people and about 80 gallons of fuel. 3 of the people were kids " 75pounds and under" we were on Vacation with it so we did not go for any high speed runs I feel I should be a round 67-70 with myself and one other. I have two more props to try Bravo one 28p four blade and a 27p three blade. I keep you updated. Oh, ya I had a Hyd lifter bad that was cracked and was not pumping up so I was down some Hp and I Dried up the Exhaust.

Still @ 4800 and 52 mph. Still have 1/2 tank last year's (treated) gas. I am almost certain fresh gas will get me to 5000 rpm. I guess I will be happy with that for now. running great!
