FRONT ROLLER SUPPORT SYSTEM
The keel of the boat must rest on the center of the front keel roll-
er system creating a three-point support system. The keel roller
system is designed to fit most boats without needing 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 it 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 added to the other keel guide roller brack-
et.
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 ad-
ditional support. Pull the assembly away from the boat. Place the
U-bolt that holds the assembly to the cross member in a lower hole
in the bracket. 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 sud-
den 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 re-
quired 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 an-
other 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 infor-
mation regarding your trailer and its components.
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 poten-
tial 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 be-
cause 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 accom-
plished 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 re-
moved. Tighten.
The wire harness for the three-light identification light must be re-
positioned where it comes from the side frame to the rear pivot to
eliminate slack, and sagging of the wiring.
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 rollers from moving while the other adjustments are be-
ing made. Final tightening will be done at the end of the adjusting
process.
