I was running a 27" Tr04 @5800 r's and getting 75ish. Running the 26" bravo, the rpms stayed at 5800 and speed dropped to 72.4. But that was without playing with engine height..I know I can go up because my h20 pressure was @20 lbs. Nathan at Hydrotech says that a good indicator of proper engine height is to have the water pressure at 17 - 18 lbs.The boat handles about the same but does require more positve trim for bow lift.I know Mark could change that issue. I will say that the overall performance is very impressive...especially the hole shot. For running and gunning or running a river like I do, this thing seems to be the ticket. A little more time will tell more.My hull is a 1994 with a replaced composite transom, so the newer hulls may be even better. I may go out tomorrow and will update the numbers if I go.
