Not always. I can build over 30psi tied to the dock in neutral on throttle only. So mine is in the engine. Likely has to do with me using the newer FI style thermostat housing with no bypass from intake to water pump. Carb motors came with the old 4 hose style.

Lets simplify. Forget speed .forget rpm ..forget it's an engine ..If I blow 15 #'s of water into a box ,the pressure in the box will be 15 #'s.. I don't see how it can get any higher than the pressure source

youre oversimplifying it. We have multiple pressure sources and not going into a closed box. It’s a flow through system and and restriction can raise pressure. I’m not debating how I’m relieving pressure. I know what I’m doing and it works. I was just curious if I would need a check valve to stop water from back flowing into intake. I didn’t think so but was checking to see if someone had a good reason I would need to.

OP- do you have the t-stat on top of the plastic spacer (+)spring or element pointed towards intake and do you have the plastic spacer oriented correctly ? maybe a pic or drawing of how you have them installed so we can see if correct.
