Several guys were right about the speedo not being overly accurate. The speedo last week showed 66-67 at WOT, but my I-phone GPS shows 71-72. Im waitng for the adapter cable to install the new GPS antenna, but I verified the phone is very accurate. Here is what I did before I went out. Previously I had 66-67 WOT at 5600 rpm before she got a little loose. Didnt get a water pressure number then. Yesterday I raised the manual jackplate about 1/8 to 1/4 inch before I left, which puts it about 3 inches below pad. The GPS showed 71-72, water press 20-22, 5600 rpm, 28P 4 blade Bravo 1, and no rooster tail. My best run hit 75, but I still have rpms to use and good water pressure. The hole shot remained unchanged (very good). What should my next step be for a little more top end, besides seat time.

Yep, those speedos are not close at all or is my 225 HO really doing 88? lol….You might try raising the motor 1/8″ at a time and keep a close eye on water pressure and steering torque. Sounds like you are getting real close on your set-up.

I know Im looking to keep water pressure at what – no less than 10/15 – but what will the change in steering torque be – what feel am I looking for? With the motor rated a 6400 rpm max, can prop/jackplate changes give me more top end by using the extra rpms. Im not that concerned with more top end, just want to make sure Im getting whats available while keeping a good hole shot and handling.

We have run several propellers from the Bravo to the Trophy on your rig. We have not run a Fury as it is newer and we have not had the opportunity. It may run well and we just dont know. The engien height is probably not set on the rig and that is where you can most easily gain.
