Protect your Impeller.
The Impeller Saver warns you if your engine’s raw water intake (thru-hull) is closed, before it’s too late. Utilizing a simple and robust sensor, Impeller Saver activates an audio alarm if the through-hull is closed, when you prepare to start your engine. With the custom LED installed, a visual warning will remain lit at all times when the valve is in the closed position.
It will save your Impeller from burning up and potentially even bigger problems
