V-SERIES BUNK ASSEMBLY
Position the bunks onto the brackets already installed to the
cross members. Attach the bunks to the bunk brackets us-
ing 3/8” x 1” hex bolts and hex flange lock nuts.
The 3/8” bolts just installed can be tightened but not over
tightened because the bunks should be allowed to rotate
slightly to conform to the boat bottom once the boat is set
on the trailer.
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
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 (if equipped with
brakes) will need care when moving the axle assembly.
REAR SUPPORT SYSTEM
1. 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. 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 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.
2. 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 rest-
ing on the center pads. A minimum of one to two inches of
clearance is desirable.
FRONT SUPPORT SYSTEM
1. 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. The bunks can run at an angle rather than
parallel with the center line of the trailer. 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
1. 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. At-
tach 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 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 check before towing.
See your ShoreLand’r Owner’s Guide for further technical
information regarding your trailer and its components.
