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 respective trailer and vehicle frames.
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 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. Reposition 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
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 desir-
able.
RB Bunk trailers would 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 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 continue to run just to the outside of the strake of the
boat. 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 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 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 itself. 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 additional
riser kit is an SS1403.
Once the height of the roller cradle assembly is established
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
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 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. 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 desired 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.
Axle Adjustment
The amount of tongue weight on your trailer can be ad-
justed 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 directedly related to the weight and center
of gravity of the boat place on it.
