Stainless Steel Four Blade Impeller 7 3/8D – BACKORDERED until August 2024


Wooldridge 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 Wooldridge 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. There are significant performance gains with the Wooldridge 7-3/8D four-blade stainless impeller and is considered an absolute must by many jet boaters. These impellers are not faster but plane quicker with a load and haul more weight. They are less apt to cavitate in rough or white water.
