It’s time to replace your boat’s impeller, if f you haven’t already done so and Spring is the beginning of your boating season. Globe Marine recommends that every boat owner replace their engine impeller once every boating season to get optimal use and reliability for your boat’s engine. Here’s why…
Stored Impellers Can’t Run at Their Best
No Worn Impellers – an impeller that’s “taken a set”
If you stored your boat this winter, the impeller shouldn’t be left in your boat’s engine or pump when first opened for spring. Why? Leaving impellers in the boat engines over the winter, especially in cold climates, can cause the impeller to “take a set.” More than likely, the impeller will still work, but you won’t get optimal water or diesel flow from it.
Likewise, if you tried to store your impeller in a special fluid to preserve it over the winter, it may still “take a set”, or worse, degrade due to the fluid. Besides these preservatives not being recommended by most manufacturers, re-installed impellers almost always are warped or damaged — not to mention challenging to re-install. The re-installed impeller still may work initially, but you won’t get optimal performance out of it. It’s bound to let you down when you need it the most.
If it’s Common Advice, it’s Good Advice
Almost all impeller manufacturers recommend replacing impellers at least once per season, so it’s a safe bet that you should probably do so at the beginning of each boating season. These recommendations have come from rigorous testing and development. Manufacturers know what the best operating conditions — and the not-so-great conditions — are for your particular impeller to run at its best. It may seem smart to save $20-$30 by re-using an old impeller, but you’ll spend more on gas and possibly even engine or pump repairs. In the long run, you’ll save money by replacing your impeller now while getting your vessel ready for the new season.
Impellers Are Affordable
Depending on your engine size and model, impellers are a small portion of the total maintenance costs for your boat. It really isn’t too much to pay for optimal engine performance and may even save you a little on fuel consumption and efficiency. It’s better than waiting for a tow or getting stranded out on the water with an overheated engine or broken pump. With those benefits, a new impeller may even pay for itself in just a few short weeks.
