TRAILER ADJUSTMENTS
The adjustment of the trailer to your boat is very im-
portant not only for the trailer, but also the boat.
Failure 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 assembly
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. The center
of the rear rollers on the roller rack should be
approximately 4” from the transom. This gives you
maximum support on the transom.
The rear cross member is adjustable forward or
backward 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 position 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 bottom
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 bot-
tom 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 assembly 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
backward on the tongue until the bow roller comes in
contact 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 desired height
required to fit your boat.
