TRAILER ADJUSTMENTS:
The adjustment of the trailer to your boat is very important 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.
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 and RB trailer, the transom
of the boat should be within 1-2” of the end of the bunk.
Roller Model
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 two bolts that attach the
ends of the rear cross member to each side frame. Slide the
assembly to another set of holes provided in the side frames
that is more desirable, and then re-attach the cross member
in the new location with the bolts just removed.
The wire harness for the three-light identification light must
be re-positioned where it comes from the black wire har-
ness tubing to eliminate slack and sagging of the wiring.
Bunks
The bunks must be positioned far enough apart to give
your boat as much stability as possible while transporting.
Position the bunks so they are located just to the outside of a strake on
your boat. This will help center your boat and assist when loading. The
bunks need to be adjusted up high enough to keep the keel from rest-
ing on the center pads. A minimum of one to two inches of clearance is
desirable.
The rear RB Bunk system would be adjusted the same
way as the full bunk trailer just described above.
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 bunks or rollers from moving while the other
adjustments are being made. Final tightening will be done at the end
of the adjusting process.
Front Support System
Bunk
The front bunks should be adjusted either in or out so that the bunk
will run just to the outside of the strake on the boat. The bunks
can be adjusted either farther in or out from the location of the rear
bunk position. Adjust the bunks up so that there is approximately 1”
clearance between the keel of the boat and the center cross member
pad.
RB and Roller
The keel of the boat must rest on the keel rollers 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.
Once the boat is resting on the roller cradle assembly, the stabilizer
pads can be adjusted. Slide the pad up against the boat bottom
by hand. It is not necessary that they carry much weight. They are
designed to 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. Then push the
assembly back against the boat. Tighten in position.
Winch Post:
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 sliding the winch post angle tube either for-
ward or backward on the tongue, thus raising or lowering the bow
eye roller. Attach the winch strap and crank winch tight.
It may also be used to keep your boat on the trailer while loading
and unloading at the ramp, especially with a roller trailer.
Attach the bow eye safety chain into the bow eye of the
boat as well. This is just another added level of protection to
keep your boat and trailer together as one unit.
Tighten all bolts and U-bolts at this time in the winch post
assembly not previously tightened.
Axle Adjustment:
The amount of tongue weight on your trailer can be adjusted as fol-
lows: To lower the tongue weight, adjust the axle assembly forward.
To increase the tongue weight, adjust the axle assembly backward.
The distance that the axle assembly has to be moved will vary be-
cause it is directly related to the weight and center of gravity on 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: Brake line and wire harness will need care when moving
the axle assembly.
NOTE: Check all fasteners, they must be tightened before tow-
ing.
Cautions / Warnings
The law requires that the white ground wire on both
the tongue wire harness and the vehicle harness be
properly grounded to the respective trailer and vehicle
frames.
