About this item

  • Increase the performance of your boat by reducing planing time and RPM requirements, letting you get on plane and remain there at lower speeds
  • Gain fuel efficiency by reducing by getting on plane quicker and plowing through the water less
  • Mounts directly to the engine's cavitation plate; the sleek black polycarbonate construction matches well with any engine color
  • Compatible with outboard and sterndrive engines from 40 HP to 300 HP
  • Includes all necessary hardware for installation


Get more performance from your boat with the Extreme Max Hydrofoil! Mounted to the cavitation plate on your outboard or sterndrive's lower unit, the hydrofoil noticeably reduces the time it takes to get your boat on plane, creating an easier driving experience and a safer operation. While on plane, the hydrofoil boosts normal driving performance, maximizing top speed while also keeping the boat on plane at lower speeds, creating more time driving on top of the water and less time plowing through it. As an added benefit, the reduced time between on-plane and off-plane adds a nice bump to your engine's fuel efficiency so you can spend more time on the water and less time at the gas dock. The hydrofoil is designed for outboard and sterndrive engines from 40 HP to 300 HP and includes all necessary hardware for installation. The sleek black polycarbonate construction matches well with any engine color. Not to be used as a step. Installation requires drilling.

These are absolute garbage. I bought two sets for two different boats and they both broke right away without being hit or stressed in an unnatural way. Don’t buy.

I recently received two of these and only ordered or needed one. I didn't open the second package until this AM because I started to install the first one and there wasn't any mounting hardware in the box. I opened the second box to look for mounting hardware and found some. I am sending back the one that was missing the mounting hardware.

I put it on my 55 hp Johnson on my pontoon and helped with overall mph and fuel usage.

It's well worth the money. I put it on my boat and I am very happy with it. I can get right up on plane with no problem at all. If you're having trouble getting your boat up on plane I recommend them.
