A marine engine is provided with an outdrive 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 outdrive 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. Wherein, the invention consists of an impeller tester which is placed in existing outdrive water supply devices, or is permanently installed in the water craft. Wherein, the invention will communicate to the operator that a sufficient supply of water is available and the water impeller will not be damaged upon starting the crafts engine. Wherein, the invention also communicates to the operator that the water impeller is functioning properly and is producing sufficient pressure to supply the marine engine with sufficient coolant so it will perform without over-heating when the outdrive unit is not supplied with a pressurized water supply.
