The Volvo Penta 3587522 is a genuine OEM 4-blade aluminum propeller engineered for Volvo Penta SX sterndrive systems. Designed to deliver improved thrust, acceleration, and handling, this propeller converts engine power into efficient forward motion while maintaining stability under load.

With a 14.25″ diameter and 19″ pitch (RH rotation), this prop is optimized for boats requiring strong mid-range performance, better hole shot, and enhanced controlespecially in heavier hulls or towing applications.

Parts Desk Insight

This is a go-to upgrade over 3-blade props when customers want better hole shot and control. You lose a bit of top-end speed, but gain way better gripespecially on heavier boats or when towing.
