TRAILER ADJUSTMENTS
The adjustment of the trailer to your boat is very im-
portant not only for the trailer, but also the boat. Fail-
ure to do so may lead to potential failure or damage to
either the trailer or boat.
Adjust as follows:
AXLE ADJUSTMENT
The amount of tongue weight on your trailer can be
adjusted as follows:
To lower the tongue weight, adjust the axle assem-
bly forward. To increase the tongue weight, adjust the
axle backward.
The distance that the axle assembly has to be moved
will vary because it is directly related to the weight and
center of gravity of the boat placed on it.
Best towing is achieved when the tongue weight is 5-
7% of the total gross load of the complete unit.
Note: Wire harnesses and brake line lines will need
care when moving the axle assembly.
REAR SUPPORT SYSTEM
Place the boat on the trailer so that the transom is
located at the rear of the support system. On a bunk
trailer, the transom of the boat should be within 1-2” of
the end of the bunk. This gives you maximum support
on the transom.
The rear cross member is adjustable forward or back-
ward to allow the trailer to be adjusted to various length
boats. This is accomplished by removing the pivot bolt
on holds each end of the rear pivot to the side frame.
Reposition the rear pivot arm into the other hole posi-
tion predrilled in the side frame.
Reattach the rear pivot to the side frame with the bolts
just removed. Tighten.
The wire harness for the three-light identification light
must be repositioned where it comes from the side
frame to the rear pivot to eliminate slack, and sagging
of the wiring.
ROLLERS
Position the roller racks so they are far enough apart
to give your boat stability while transporting. When the
desired width is achieved, move the roller rack system
so that the rollers are just to the outside of a strake.
The rollers need to be adjusted so that you have a
minimum of one to two inches of clearance between
the keel of the boat and the center cross member
pads. This will help center the boat when loading and
unloading.
When the desired position is determined, tighten only
enough to hold the rollers from moving while the other
adjustments are being made. Final tightening will be
done at the end of the adjusting process.
FRONT ROLLER SUPPORT SYSTEM
The keel of the boat must rest on the center of the
front keel roller system creating a three-point support
system. The keel roller system is designed to fit most
boats without needing any further adjustment, how-
ever there are considerable differences in boat bot-
tom designs and certain lines of boats will require a
riser. One riser is shipped inside the rear keel guide
roller bracket. This can be removed and bolted on the
bottom side of the keel guide roller bracket so it is be-
tween it and the keel cradle itself. This will raise the
front end of your boat 3/4”. In the event that this is not
enough, an additional one can be added to the other
keel guide roller bracket.
Once the height of the roller cradle assembly is es-
tablished the stabilizer pads can be adjusted. This is
accomplished by sliding the pad up against the boat
bottom by hand. It is not necessary that they carry
much weight. They are designed to just give your boat
added stability while being towed. It may be necessary
to adjust the assembly up so that they can be moved
further apart giving additional support. Pull the assem-
bly away from the boat. Place the U-bolt that holds
the assembly to the cross member in a lower hole in
the bracket. Push the assembly back against the boat.
Tighten in position.
WINCH POST
Once all other adjustments are complete the winch
post can be adjusted. Slide the winch post base back-
ward on the tongue until the bow roller comes in con-
tact with the boat.
This bow roller needs to be positioned directly above
the boat bow eye to prevent your boat from moving
forward in the event of a sudden stop. It can be moved
up or down by removing the back bolt that mounts the
winch head to the base. When this bolt is removed,
the head can be rotated up or down to reach the de-
sired height required to fit your boat. Once in this posi-
tion, align the closest pair of holes in the brackets and
reinsert the bolt just removed. Tighten.
Attach the winch strap and crank winch tight. Attach
the bow eye safety chain into the bow eye of the boat
as well. This is just another level of protection to keep
your boat and trailer together as one unit.
