Stainless Steel Four Blade Impeller 7 7/8
Stainless Steel Four-blade Impellers improve longevity and performance in outboard jet motors.
On an outboard jet, the impeller is what vacuums up the water, then accelerates it and shoots out a solid stream to provide power. Many impellers are aluminum, which is softer and more prone to wear and chipping than stainless steel. The advantages of a stainless impeller are many, including its resistance to abrasion and deterioration when rocks or sand are sucked through the jet unit. That means it requires less maintenance.
