• For outboards over 50 HP
The Attwood Hydro-Stabilizer gives outboards and stern drives a performance boost, improving both stability and handling. The Hydro-Stabilizer outperforms ordinary flat hydrofoils by reducing drag when the hull goes on plane. Installs on a large variety of motor styles and sizes with included stainless steel bolts and lock nuts. Wings constructed of black moulded plastic. The Hydro-Stabilizer quickly puts the boat on plane, and helps pull skiers out of the hole faster. Even at lower RPMs, it keeps the boat on plane. The wings provide a smoother, more stable ride and reduce ventilation in turns.
