Regular impeller maintenance is essential for your outboard engine's cooling system. Keeping a spare impeller on board can prevent unexpected breakdowns and costly engine damage from overheating.

Thank you!

No one informed us that there would be 2 separate packages of 5 each for total of 10 switches. This created some concerns regarding a possible shortage.
