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.
Adjust as follows:
AXLE ADJUSTMENT
The amount of tongue weight on your trailer can be adjusted
as follows:
To lower the tongue weight, adjust the axle assembly for-
ward. To increase the tongue weight, adjust the axle back-
ward. The distance that the axle assembly has to be moved
will vary because it is directly related to the weight and cen-
ter of gravity of 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: Wire harnesses and brake line lines will need care
when moving the axle assembly.
REAR SUPPORT SYSTEM
Place the boat on the trailer so that the transom is located
at the rear of the support system. On a bunk trailer, the tran-
som of the boat should be within 1-2” of the end of the bunk.
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 holds
each end of the rear pivot to the side frame. Reposition the
rear pivot arm into the other hole position predrilled in the
side frame.
Reattach the rear pivot to the side frame with the bolts just
removed. Tighten.
The wire harness for the three-light identification light must
be repositioned where it comes from the side frame to the
rear pivot 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 the outside of a
strake that your boat may have. This will help center your
boat and assist when loading. The bunks need be adjusted
up high enough to keep the keel from resting on the center
pads. A minimum of one to two inches clearance is desir-
able.
FRONT BUNK SUPPORT
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 approxi-
mately 1-2 inches clearance between the keel of the boat
and the center cross member pad.
WINCH POST
Once 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
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.
Adjustments are now complete. Double check your boat for
fit. If the desired fit has been achieved, tighten all fasteners
that may have either been left loose or have been loosened
to do the adjusting.
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.
Recheck all fasteners on the complete trailer to make
sure they are all tight and ready for towing. All fasteners
should be periodically checked before towing.
See your ShoreLand’r Owner’s Guide for further technical
information regarding your trailer and its components.
