TRAILER ADJUSTMENTS
The adjustment of the trailer to your boat is very im-
portant 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 assem-
bly forward. To increase the tongue weight, adjust
the axle 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 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 transom 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
desirable.
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 approximately 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 back-
ward on the tongue until the bow roller comes in con-
tact 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 tow-
ing. 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 fasten-
ers should be periodically checked before towing.
See your ShoreLand’r Owner’s Guide for further
technical information regarding your trailer and its
components.
