NOTE: All nuts and bolts must be
tightened before towing.
The law requires that the white
ground wire on both the tongue wire
harness and vehicle harness be
properly grounded to the trailer and
vehicle frames.
TRAILER ADJUSTMENTS
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.
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 cross member is adjustable
forward or backward to allow the trailer
to be adjusted to various length boats.
This is accomplished by removing the
pivot bolt on each end that holds the rear
pivot arm to the side frame and the rear
pivot offset weldments.
Once the rear pivot arm assembly is
removed, remove the two additional
bolts on each side frame that mount
the rear pivot offset weldments to the
side frame. Move them to the desired
location and remount to the side frames
with the bolts just removed. Reposi-
tion the rear pivot arm between the
two rear pivot offset weldments just
installed. Secure in place using the two
pivot bolts removed earlier. Tighten.
The wire harness for the three-light
identification light must be re-positioned
where it comes from the black wire
harness 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 the boat’s strake. 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 1” to 2” of clearance is desirable.
RB Bunk trailers will be adjusted the
same way.
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 the strake. The rollers need to
be adjusted so that you have a minimum
of 1” to 2” 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
continue to run just to the outside of the
strake of the boat. The bunks can run
at an angle rather than parallel with the
centerline of the trailer. Adjust the bunks
up so that there is approximately 1”
clearance between the keel of the boat
and the center cross member pad.
RB & 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, however there is
considerable differences in boat bottom
designs and certain lines of boats will re-
quire 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 between it and the keel cradle.
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. The ad-
ditional riser kit is an SS1403.
Once the height of the roller cradle
assembly is established the stabilizer
pads can be adjusted. Slide the pad
up against the boat bottom. It is not
necessary that stabilizer pads 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 assembly
away from the boat. Place the U-bolt
that holds the assembly to the cross
member in a lower hole in the brack-
et. 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. The 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
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. Attach the
winch strap and crank winch tight.
Attach the bow eye safety chain into the
bow eye of the boat as well. This is just
another level of protection to keep your
boat and trailer together as one unit.
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 loos-
ened to do the adjusting.
Re-check all fasteners on the com-
