8. Forgetting to Service the Water Pump Regularly
What It Does: The pump impeller is made of a flexible, rubber-like material that degrades over time. Changing it ensures water flow, but equally important, changing it regularly ensures that the screws that hold the gear-case housing together do not corrode and lock tight.
Result Of Neglect: The most obvious and immediate effect is an overheating engine, which will at best end your boating day, and at worst burn up your engine.
Cost To Perform: It can cost $200 to $300 to have the water pump rebuilt by a professional. If you’re handy, you can do it in your driveway for $100 or less.
Penalty: Even if the water pressure gauge indicates all is well on a threeyear- old pump, those screws might be welding the gear case together. If they do, you’ll replace the gear case for thousands, not hundreds, of dollars.
