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 two bolts 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 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 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.
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 run just to the outside of the strake of 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 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 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 giv-
ing 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 roll-
er. 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.
Tighten all bolts and U-bolts at this time in the winch post
assembly not previously tightened.
Attach the bow eye safety 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.
Axle Adjustment:
The amount of tongue weight on you 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 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 assembly.
NOTE: Check all fasteners, they must be tightened
before towing.
Cautions / Warnings
The law requires that the white ground wire on both
the tongue wire harness and the vehicle harness be
properly grounded to the respective trailer and vehicle
frames.
