Outboard Boat Engine Stabilizer Plate or Planing Fin
Outboard boat engine stabilizer plates or boat planing fins eliminate visibility hazards during acceleration, porpoising, improves performance, and eliminates cavitation. These anti-drag stabilizers are mounted under anti-cavitation plate of outboard motors and inboard motors. Once cruising speed is reached, reduce RPM and still maintain same speed. Save fuel and wear and tear. Stabilizers extend aft of the motor and reduce wakes for skiers. More solid water around the propeller improves performance and top speed overall.
