water pressure gauge reading

[Kenny Guess]

If you have the optimax 115 on your boat, and have a water pressure gauge, what should it read at idle and does it change when running....? thanks, kenny

I'm no machanic but when at a idle it probably won't move much but when running it should go up just make sure water is coming out of the side hole on your motor.

My 1.5L Opti runs 4-6 psi at idle and 14-16 psi at wide open throttle.
