For starters, I'm a little new to this jet boat thing. I've got a Spectra mini day cruiser thats getting a fresh 460 engine which should be in the low 400 hp range. Its got a Berkeley E pump with an A cut impellar that has also been gone through. I've already installed a gate valve on the water line directly from the pump but was wondering if I should run a pressure relief valve as well? Will I see pressures high enough to worry about blowing a gasket with a stock pump setup? Thanks in advance for any advice.
