This is a must for all jet boats. This spring loaded adjustable from 7-25psi water pressure
relief valve system is perfect for bleeding off excess engine water pressure caused by
pressure spikes in an engines cooling system.  water flows freely when water pressure
exceeds the set designated pressure.  Keep high pressure spikes from damaging your
engine. Run directly from your jet drives  to the fittings supplied. Simply adjust your water
temperature using a gate valve not included. Connect a water pressure gauge to your
engine and monitor the pressure. Adjust the spring loaded relief valve to maintain the
proper pressures. See our you tube videos explaining how to install your kit and how it
works...
