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.
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
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 of the boat place on it.
Best towing is achieved when the
tongue weight is 5-7% of the total gross
load of the complete unit.
To move th e axle assembly, loosen the
U-bolts that secure the assembly to the
side frames. Move the assembly to the
desired location, then re-tighten U-bolts.
NOTE: Brake line and wire harness will
need care when moving the assembly.
Rear Support System
Place the boat on the trailer so that the
transom is located at the rear of the
support system. On an RB bunk trailer,
the transom of the boat should be within
1-2” of the end of the bunk. 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 pivot
is adjustable forward and backward to
assist in adjusting the trailer to various
length boats. This is accomplished by
removing the pivot bolt that attaches the
rear pivot to the side frame and then
sliding the assembly to the desired
position and re-attaching with the pivot
bolt just removed. The wire harness for
the three-light identification light will
have to be rerouted as well.
RB Bunks
Make sure the bunks are 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 that your
boat may have. 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.
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 one set of the rollers are
just to the outside of a strake if possible.
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
RB and Roller
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.
Once the boat is positioned on the front
roller system, 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 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
Now that 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.
Loosen the three 1/2” hex bolts that
clamp the winch holder channel to the
winch post. Attach the winch strap into
the bow eye and slide the winch holder
channel up or down to the desired
position as you crank the winch tight.
Once the bow roller is located just above
the bow eye, tighten the three 1/2” hex
bolts that clamp the winch holder
channel to the winch post. Tighten the
U-bolts that secure the winch post
assembly to the tongue. Attach the bow
eye safety chain into the bow eye of the
boat as well. The chain is another level
of protection to keep your boat and
trailer together as one unit in the event
of an accident. It may also be used to
keep your boat on the trailer while
loading and unloading at the
ramp,especially with a roller trailer.
Adjustments are now complete. Double
check your boat for fit. If desired fit has
been achieved, tighten all fasteners that
may have either been left loose or have
been loosened to do the adjusting.
Re-check all fasteners on the complete
trailer to make sure they are all tight and
ready for towing. All fasteners should be
periodically check before towing.
The law requires that the white ground
wire on both the tongue wire harness
and vehicle harness be properly
grounded to respective trailer and
vehicle frames.

for further technical information
regarding your trailer and its
components.
