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 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 RB SUPPORT SYSTEM
Place the boat on the trailer so that the transom is
located 1-2” from the rear of the bunks. 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 vari-
ous length boats. This is accomplished by removing
the pivot bolt that 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.
Position the RB bunk assemblies so they are far
enough apart to give your boat stability while trans-
porting. When the desired width is achieved, move
the RB bunk assemblies so that they are just to the
outside of a strake.
The RB bunk assemblies 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 bunks 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, however
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 bottom
side of the keel guide roller bracket so it is between
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. Then 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 desired
height required to fit your boat. Once in this position,
align the closest pair of holes in the brackets and
reinsert the bolt just removed. Tighten.
