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 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 “RB” SUPPORT SYSTEM
Place the boat on the trailer so that the transom is located
1-2” from the rear of the bunks. 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 that 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.
Position the RB bunk assemblies so they are far enough
apart to give your boat stability while transporting.
When the desired width is achieved, move the RB bunk as-
semblies so that they are just to the outside of a strake.
The RB bunk assemblies 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 from moving while the other ad-
justments are being made. Final tightening will be done at
the end of the adjusting process.
FRONT ROLLER SUPPORT SYSTEM
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 need-
ing any further adjustment, however there are considerable
differences in boat bottom designs and certain lines of boats
will require a riser.
One riser is shipped inside the rear keel guide roller bracket.
This can be removed and bolted on the bottom side of the
keel guide roller bracket so it is between and the keel cradle
itself. This will raise the front end of your boat 3/4”. In the
event that this is not enough, an additional one can be add-
ed to the other keel guide roller bracket.
Once the height of the roller cradle assembly is established
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
just 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 as-
sembly 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
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.
