When you start your boat, if the water does not flow out and back in fast enough, water will get caught between the pump's impeller blades. This will quickly result in the destruction of your pump. Monitor water flow each time you start your engine and inspect the impeller every spring.
Always carry an extra impeller because they will eventually break. The only caveat is that you have to follow the schedule of preventative maintenance, rather than only looking after them so they don't break in the meantime.
