Powertech does have 3 and 4 blades for them. I've had better luck with the powertechs on a few setups. So far a 31 Capehorn, a 31 Contender, and one Intrepid, liked the OFS4's the 33 Freeman Cat liked the OFS3's. Maybe the Yamaha 4 blades will be out soon though.

Congrats Chris !!

Good deal. I'd still get a water pressure guage though. We've caught problems (early) with poppet valves, debris over the intakes, etc.. by having a water pressure gauge. If we didn't have it, we would have ran it until the overheat alarm shut us down. The pee stream is a decent indicator, but how often do you look back at it while running.

Put a water pressure guage on your engine. You should have one anyways. When you say 1 3/4 inches higher then normal. whats "normal" With that much setback, the cavitation/ventilation plates should be roughly 2 1/2 to 3 inches above the hull anyways. You might have your engines too low still. At a fast cruise speed, trimmed however the boat likes to be normally, can you see the cavitation plate? Low Correct
