Hydro Stabilizer 9400-7 - Attwood
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 molded 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.

Major Improvement
by Colgan from Arkansas City, Kansas on August 13, 2013
The stabilizer is great at reducing bow rise, mine personally by around 40%. Prior to installation my boat would not maintain plane under 12 mph, now I am able to hold plane down to about 8.5 mph while pulling a tube with two younger children. I did not notice any top end speed changes. Only thing I did not like was that in a white capping lake the back end of the boat would occasionally pull some with the undercurrent while on plane now. it was not violent or scary by any means just something to be aware of. I would definitely buy this product again. My boat is an 88 Larson 18 foot bow rider with 175 horse mercruiser, I run a 21 pitch stainless 3 blade prop no other mods on boat.
