IMPORTANT: 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: To lower
the tongue weight, move the axle
assembly forward. To increase the
tongue weight, move 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 repositioned
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 as-
sist 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 mini-
mum 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 deter-
mined, tighten only enough to hold
the 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
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 models 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 bottom side of the keel guide
roller bracket so it is between it and
the keel cradle. See Detail Q. 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 from the centerline
of the trailer 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. Push the assembly back
against the boat. Tighten in position.
Winch Post
Slide the winch post base 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 remov-
ing 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. 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 unload-
ing at the ramp, especially with a roller
trailer.
Adjustments are now complete.
Double check your boat for fit. If
desired fit has been achieved, tight-
en all fasteners that may have ei-
ther 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 periodical-
ly checked before towing.
