1973 23' cc with bracket performance??

[travisrandall]

I have bought Diego Toiran's Reel Smoker. It has a full transom with an Armstrong bracket and now a 225 Merc carbed engine. what kind of prop should I be running? Diego had a 16 pitch on with the OMC, seemed kinda low to me. My tach is giving me problems, but hopefully I have it fixed now, just not much time to water test it. We have the engine hung as low as possible and it seems to want to blow out or cavitate the 21 pitch prop that is on it. I can run 35 mph, gps, and it seems comfortable. My question is when you get the pad of the hull on top of the water is the boat high out of the water or do I have something else wrong? I noticed that I cant open the throttle right away to get on plane I have to ease into it. any ideas?
