Remove one of the brass plugs from the port in the brass block on the
left brake caliper that best aligns with the routing of the line. Note also
that the bolt holding the brass block to the caliper can be loosened so
that the brass block can be rotated to better accommodate the angle
that the brake line approaches the block on the caliper. Thread the
brake line fitting into this port to hold the line in position making sure
that the line does not rub or touch the spring. Re-tighten the bolt in
the brass block if it has been loosened to rotate the block.

Route the line down the back side of the axle and se cure
to the axle with the five (5) clamps and self tapping screws.
Note that the axle is pre-drilled for the mounting screws.

Route the brake line over to the brass block on the right brake caliper.
Remove both plugs on the right caliper block. Thread the other end of
the brake line into one of the ports on the brass block. Thread the 18”
brake hose male end into the other port from which the plug was re­moved and tighten. Position the brass block so that neither the hose nor
the brake line will contact or rub the spring. Tighten all fittings.

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 cente r of the rear rollers on the roll er rack should be
ap p ro x im a t e l y 4” fr o m t h e tr a n s o m . T h i s gi v e s 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 bolt s 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 wher e it comes from the black wi re har­ness tubing to eliminate slack and sagging of the wiring.

Bunks
Th e bunk s mus t be pos itio ned fa r eno ugh apart to giv e
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 rest­ing on the center pads. A minimum of one to two inches of clearance is
desirable.

Th e re ar RB Bunk sy stem wou l d be adjus ted the sa m e
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 bun ks or ro ller s fro m mov ing wh ile the oth er
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 for­ward 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.

At tac h the bow eye safet y 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 fol­lows: 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 be­cause 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 tow­ing.

Cautions / Warnings

Th e law requ ires th at the wh ite gr ound wi re on bo t h

properly grounded to the respective traile r and vehicle
frames.
