300 HPDI water pressure

[Bass1980]

My 300 hpdi's water pressure is at 22 at idle. When on throttle it jumps to 30psi and max out on the gauge eventually. Anything I should be worry about. My research I hear people say as long as it's above 12 psi I should be fine but I just have an uneasy feeling that my numbers are not similar to anyone's I've seen online. Prop to pad is 3.5 currently. I am looking to adjust it to 3.25 and possibly even 3" to to gain some top end. Is 12psi the number I need to watch once I see the dip lower back the prop to pad?

A 300 hpdi with 22 psi at idle?? Either you have a unicorn or a bad gauge. I would try a different gauge as I have never seen a Yamaha v-6 two stroke with hardly any pressure at idle let alone 22psi. My guess because of our warm winters your gauge froze. CJ

What's the normal numbers at idle and wot? Thanks

I noticed yesterday that at idle my VZ225 shows "0" at idle. It actually alarmed me at first but the "pee" stream was good. I actually forgot to check it yesterday while I was running it above idle.

My 300 doesn't indicate any pressure at idle. 20-plus running down the lake.
