Permatrim keeps your boat permanently in trim, gets you on the plane quicker and allows you to plane at slower speeds in rough water.  And you do not have to move your passengers forward to get on the plane.

There are 4 sizes available:

Small- Up to 30hp

Medium- 30 to 60hp

Large- Over 60hp (Optional heavy duty option available is when required.)


Permatrim is a one piece construction of solid aluminium fixed by 8 or 10 countersunk screws that ensure your cavitation plate will not break during turns or in rough conditions.

The Permatrim is NOT a foil with two wings. The Permatrim is an extension of the cavitation plate. Turned down side edges direct water to the rear giving additional lift.

Each Permatrim is correctly sized to suit each engine and tuned to your boat size.  If you have a new Etec, Verado, or four stroke engine the Permatrim will fit!

Permatrims are made of marine grade aluminium and is powder coated to the colour of your engine.

Faster planning times.

Easy do it yourself installation.

Boarding step!

Improves economy.
