I bought a 2004 Chaparral Sunesta 236 deckboat with a 5.0 fuel injected Merc. When boat was clean and I put in the lake with just me, I got 45 mph with 4600-4700 WOT with the new 4 blade Michigan Wheel Vortex 14 1/2 x 18. . Now that it's been in the water over a month and has scum on it I am getting WOT of 4000-4200 , 38-40 mph with 4 people in boat. Barely pulled me out of water on slalom ski. It was a real fight.
Thinking I should change prop for skiing. Should I stick with 4 blade and go to 17"? Looking for some advise on what's best.
Also, how do I determine what gear ratio is in this Alpha One Gen II?
