What are the major benefits of installing a Permatrim on my
Although hull design, engine transom mounting height and other factors may
affect the performance of your Permatrim, there are many benefits to installing
A Permatrim will assist your boat in coming up on plane faster, with less power
needed to do so and with decreased bow rise. The minimum planing speed is
decreased leading to better fuel economy and decreased hull porpoising
at engine/drive trimmed-up speeds.
Why are Permatrim
more expensive than "other" brands?
Permatrim are manufactured from marine-grade aluminum instead of a
flimsy plastic used by other brands.
Permatrim are custom made to fit your specific outboard and the outboard's
horsepower range. Permatrim are powder coated to closely match the color of
your outboard. They are not painted so they will not match perfectly with all
outboards, but the powder coating will hold up to the continuous underwater use
whereas paint will not.
We are the only U.S. distributor of Permatrim. We import them from
the New Zealand Manufacturer,
Permatrim NZ,in large quantities. We
believe Permatrim are worth the extra effort. You will too!!!
Are Permatrim hard to install?
Installing a Permatrim is not difficult. We have provided a Permatrim Installation Guide ,with pictures, to assist you. Pictures provided show a Permatrim installation
on a F75 Yamaha outboard. All outboard models will install in the same fashion
or very similarly. The only difference is in the number of bolts needed for
All Permatrim come with stainless steel truss head bolts, flat washers and ÂĽâ€ť ny-lock
nuts. The tools that are not provided are: An electric drill with a decent 1/4"
drill bit, 7/16â€ť wrench, Phillips-head screwdriver and a small amount of marine
sealant (for use around each of the bolts). You can purchase a tube of marine
sealant in black or white with the purchase of a Permatrim. Check the â€śaddâ€ť box
of the preferred sealant color on the same page as the Permatrim you wish to
I can not locate a Permatrim color for my engine?
offer four basic Permatrim colors: Honda Silver, Yamaha Grey, Mercury Black and
OMC/Bombardier White. There are some engine models that do not have a matching
color Permatrim. These include older model Evinrudes that are black or grey,
Tohatsu blue, Suzuki metallic silver and possibly a few others.
There is a Permatrim to fit most outboard engines and in these rare cases where
there is not a color match you may pick another color in the same model. For
example, if you have a dark blue, 2001 Evinrude 4-stroke, 70hp engine the
Permatrim model would be an â€ś001â€ť, but because there is not a dark blue plate
black may be substituted.
Of course there is also the option of an 001 Silver, an 001 Grey or an 001
White. Itâ€™s all up to you.
read somewhere that installing a Permatrim will slow my boat speed down. Is this
The engineâ€™s height on the transom is the most important factor when it comes to
a Permatrimâ€™s performance. A Permatrim is designed to have water flow under the
Permatrim. If there is a significant amount of water flow over the top of the
Permatrim you will see some speed loss. That speed loss is almost always an
indicationthat the engine is mounted too low on the transom.
transom-mounted outboards, the engine height is determined by the location of
the engines anti-ventilation plate. The Permatrim is mounted to this AV plate.
To verify the outboard installation height, trim your engine all the way down
and take a straight edge and place it at the bottom side of the AV plate. Carry
that straight edge forward and see that the straight edge is now
with the hull bottom. At this level the outboard is at a height that will allow
adequate engine performance and at a â€śsafeâ€ť height for engine manufacturers and
most cases an outboard engine may be mounted higher than this "safe" level. One
inch higher is typical especially when running a stainless steel propeller.
Stainless props will stay hooked up better at higher engine heights and higher
engine trim angles. In most cases one hole up (from where the AV plate is level
with the hull bottom) will get the top of the engines AV plate out of the water
while planing. With this engine height, the Permatrim will mostly have water
flow across the bottom. With the engine trimmed down-you will get the full
benefit of the Permatrim (lower planing speed, less bow rise etc.). To gain
speed you just trim the engine up. This will change the angle of the Permatrim
and keep it from running through the water which would lessen its
sum it up: engine height on the transom is crucial for optimal performance from
you engine. With or without a Permatrim installed.
