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 “RB” SUPPORT SYSTEM
Place the boat on the trailer so that the transom is lo-
cated 1-2” from the rear of the bunks. 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
that 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.
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, 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 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.
