ABSTRACT:
A marine engine is provided with a drive unit which incorporates a water impeller to supply water to the marine engine in order to maintain proper engine cooling. Devices are currently available that allow the watercraft's engine to be started when the craft is not in actual service. These devices attach to the crafts out drive unit and they provide for water, from a household faucet, to be supplied to the water impeller. These devices have no form of measurement to communicate to the operator that a sufficient amount of water is initially being supplied to the water impeller to prevent damage to that component nor do they communicate if the water impeller is capable of producing sufficient suction to feed the crafts engine with sufficient coolant so that the engine will not over-heat when the craft is placed in its operating environment. The present invention includes an impeller tester which may be placed in existing drive water supply devices or which may be permanently installed in the water craft. The apparatus communicates to the operator of the craft that a sufficient supply of water is available and that the water impeller will not be damaged upon starting and running the craft's engine.
