      Johnson Outboard Impellers

      An overheated boat motor will put a damper on all of your plans and a dip into your pocket. One of those hidden parts that can quickly lead to trouble if gone unchecked is your outboard motor’s water pump. To avoid serious engine problems, the impeller must operate at peak performance. Over time its blades can become worn or cracked. That’s when it’s good to know that Wholesale Marine carries a full line of dependable Johnson impellers and can flat rate ship them out to you the same day.

      All About Impellers

      Impellers are designed with rubber vanes that circulate around a hub inside the water pump. To keep your outboard from overheating, these vanes flex to draw water into and through your motor to cool it down. Vanes wear out for several reasons. Operating your boat in silty or sandy conditions will cause grit to draw in and around the impeller, and wear the vanes down. Long storage periods in dry dock allows the rubber vanes to crack and become rigid.

      One way to keep your outboard’s impeller operating optimally is to always use a set of water muffs on your gearcase when dry idling. This action will allow water to continue to circulate throughout your system, keeping your impeller, and more importantly your motor, safe. Johnson impellers are built to last and are economically priced to keep up with your motor’s recommended replacement schedule, typically every 100 hours of operation or when sitting in storage for several seasons.
