Why Regular Impeller Replacement Matters
The impeller draws in water to circulate through the engine for heat dissipation. Over time saltwater exposure debris dry running or wear can cause the rubber blades to crack deform or break off—reducing water flow and risking engine damage like warped cylinders or seized pistons. Marine sources suggest inspecting and replacing it every season or after 100 hours of use to help avoid repair costs and support performance.
