TRAILER ADJUSTMENTS
Axle:
The amount of tongue weight on you 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 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.
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
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.
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
a d j u s t m e n t s a r e b e i n g m a d e . F i n a l t i g h t e n i n g
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. 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
a s s e m b l y a w a y f r o m t h e b o a t . P l a c e t h e U -
bolt that holds the assembly to the cross mem-
ber in a lower hole in the bracket. Then push the as-
sembly 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. It can be moved up or down by
sliding the winch post angle tube either forward or back-
ward on the tongue, thus raising or lowering the bow eye
roller. Attach the winch strap and crank winch tight.
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 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.
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.
See your ShoreLand’r Owner’s Guide for further technical
information regarding your trailer and its components.
