Transform Your Boating Experience: Say Goodbye to Cavitation Issues
Boats that suffer from cavitation issues will greatly benefit from using a Permatrim.
By increasing the size of the factory cavitation plate by up to four times, and the additional benefit of the turned down sides, Permatrim reduces the chance for the propeller to draw in air that will create an air pocket around the Propeller - one of the causes of cavitation/ventilation.
By having a larger cavitation plate & the turned-down sides, the Permatrim condenses/compresses the water around the Propeller, helping to eliminate the chance of air being drawn into the Propeller.
Lowers Planing Speeds
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/sterndrive.
Gets Boats Onto The Plane Faster
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 at the same amount of rpm.
Having more stern lift and trim control allows you to hold 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.
Improves Rough Water Handling
A Permatrim enables a lot more control of trim angles and the ability to eliminate porpoising, and allows you to plane at a lower speed
Trim control is important as you need to be able to adjust your bow to suit the conditions and make your boating excursions safer and more comfortable
As the permatrim is up to four times larger than the factory cavitation plate, your trim control is greatly enhanced, allowing you to trim the bow down hard in a rough head sea or will allow you to hold the bow higher in a following sea , giving you a lot more trim control and a more comfortable ride.

Because a Permatrim gives you more trim control and stern lift, eliminating Porpoising issues is a breeze, just a small adjustment down on the trim button is usually all it takes to stop the Porpoising.
Permatrim is available for all the major outboard brands and sizes. Drop us an email with your details and we’ll get you sorted.

Rips very easily
Color: Banana
My 12 pound Shih Tzu was able to rip through this in less than 12 hours. Not worth the money.

Such a fun novelty item but so cute and the pups love them!
Size: 7"
My grand dogs loved them so much I had to actually buy a set for our house and their mom's house! :) Perfect size for our pug and chug. Fits in their mouth perfectly and funny enough they always have the right end in their mouth. The other day our pug went to sleep with it in her mouth for an hour!

Not great
Size: 7"
Thread is already coming out. The last one she had lasted 2 years. (Was not bought on here) The only reason for ordering her a new one was because we left her old a hotel.
