Permatrim Y5 40-60hp Hydrofoil

By increasing the size of the Factory cavitation plate by up-to four times, the Permatrim will provide a lot more stern lift, so you can stay on the Plane at a lower speed.

In rough conditions, it is far safer to be able to stay on the plane at a slower speed. Permatrim will help you do this by increasing the stern lift & trim control of your outboard.

By increasing the size of the cavitation plate by up-to four times, the Permatrim increases the stern lift and trim control, to plane faster.

The Permatrim extends out past the end of the cavitation plate, to catch the wasted water from the top of the Propeller (the hump of water out the back), holding this water down and forcing it rearward, this increases the stern lift and thrust from your outboard/sterndrive from the same amount of rpm.

By having more stern lift and trim control, this allows you to holds the bow down and stern higher, so the boat will plane out flatter, which will help the boat rise up onto the plane easier, also providing better forward vision from not raising the bow so high.
