If your engine has a clutch then you need a water pump. Our pump is a manufactured by Enforcer RC Boats and is specific in design for use with gas model boat engines. The pump operates from the negative and positive pressures generated inside the engines crank case while running. These pressures are fed into the pump by a small tube connected to a “pulse” fitting on the engine / intake manifold, and then to the “pulse” input on the pump. Once the engine has been started the pump begins to function drawing water from the pick-up source into the pump suppling water cooling to the head and or the exhaust manifold and or header. The pulse is strongest when the engine is at a lower idle RPM which is the only time the pump is necessary. During idle the clutch is disengaged and the engine relies on the water pump to deliver the water cooling. Once the boat is accelerated to speed the water pressure overtakes the pump.
Our water pump is easy to install and is powered by your engines crank case pulse pressures. Instructions are provided to show you how to make all connections. Made in the USA.
