ok wasnt sure if you were taking water pressure at the hose or right off a port on the block. GOTCHA!

Sorry im new to the whole non drive water pickup stuff. Now im wishing i knew this last week! Just drop'd the motors back in.

I have pressure relief valves (I have Bravo Drives with low water pick-ups). The boat was plumbed to dump on the sides, exactly due to the reason you cite, so you can see when the valve is open and it is working. I had a pressure relief valve last summer stop, and I blew a recirculation hose apart, had it replaced the same day (the hose), and blew that apart too. The shame of it all is all I had to do is look back down the side of the hull as I was running, but I became complacent.


I had Bob Wallace at Offshore Performance (here in souht Jersey), replumb and replace both pressure relief valves.

The two outlets that you see one is for the bilge pump, and the other outlet is for the pressure relief valve. Twin engine boat, each side is plumbed identically (understandably).

What pressures are u guys seeing. Is 35/40 psi to high. Mind u its only at 100+ im not up there very long
