High Water Pressure on gauge

Mine (original analog) goes all the way around and hits the needle on the back side. But it doesn’t fall all the way back to zero either. Don’t know if there is a way to reset or re-calibrate.

Depending on the engine height, trim angle and speed mine will do that. Curious what your pad to prop measurement is and what speed/rpm you’re running?

Minimum pressure at wide open throttle should be about 12PSI. If you are running WOT and trimmed out properly, and still getting 30 psi, I’d say your engine is too low. Raise it on the jack plate until you either gain rpm with no increase in speed, or water pressure drops below 12psi. I’d start out at 3″ PTP and go from there. Were you having hole shot problems before you started messing with the engine height? If so, what was happening. What kind of prop are you running, and what pitch?

Adjusted engine height when first got it to get a hole shot that I liked. I think the pad to prop measurement was 3-1/2 inches. Really not positive about that since I made several changes. Speed was around 60-61 with RPM around 5600.

What prop and pitch are you turning? Mine came at 3.25″ and I’ve gone down a 1/4″ and up as much as a 1/2″ though like it best all around where it was at. I’ve tried a few props on my FTD with the 150 4-stroke and a 24″ Trophy with all holes out and no exhaust ring is best all around in my experience. I’ve had it up to 66 before running out of water psi/rpm when light and in good weather.
