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.
TRAILER ADJUSTMENTS
The fitting 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.
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
assembly 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 place on it.
Best towing is achieved when the
tongue weight is 5-7% of the total
gross load of the complete unit.
NOTE: Brake line and wire harness will
need care when moving the assembly.
REAR SUPPORT SYSTEM
Place the boat on the trailer so that
the transom is located at the rear of
the support system. On an RB 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 each end that holds the rear
pivot arm to the side frame and the rear
pivot offset weldments. Once the rear
pivot arm assembly is removed, remove
the two additional bolts on each side
frame that mount the rear pivot offset
weldments to the side frame. Move them
to the desired location and remount
to the side frames with the bolts just
removed. Reposition the rear pivot
arm between the two rear pivot offset
weldments just installed. Secure in
place using the two pivot bolts removed
earlier. Tighten.
The wire harness for the three-light
identification light must be re-positioned
where it comes from the black wire
harness tubing 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 to the outside of the strakes 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
resting on the center pads. A minimum
of 1” to 2” of clearance is desirable.
RB BUNK trailers would be adjusted the
same way.
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 the strakes. The rollers need
to be adjusted so that you have a mini-
mum of 1” to 2” 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 deter-
mined, tighten only enough to hold the
bunks or rollers from moving while the
other adjustments are being made.
Final tightening will be done when all
adjustments have been made.
FRONT SUPPORT SYSTEM
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
strakes of the boat. Adjust the bunks up
so that there is approximately 1” clear-
ance between the keel of the boat and
the center cross member pad.
RB AND ROLLER
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 needing any fur-
ther adjustment. An SS1403 riser kit is
available which will raise the front of
the boat 3/4”.
Once the height of the roller cradle
assembly is established the stabilizer
pads can be adjusted. Slide the pad
up against the boat bottom by hand. It
is not necessary that they carry much
weight. They are designed to give your
boat added stability while being towed.
It may be necessary to adjust the
stabilizer bunks up so that they can be
moved further apart giving additional
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. Then push the
assembly back against the boat. Tighten
in position.
WINCH POST
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 (1/2” X
4-1/2” hex 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 the 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.
It may also be used to keep your
boat on the trailer while load-
ing and unloading at the ramp,
especially with a roller trailer.
Adjustments are now complete.
Re- check your boat for fit. If the de-
sired fit has been achieved, tighten all
fasteners.
All fasteners should be periodically
tightened before towing.
See your ShoreLand’r Owner’s
Guide for further technical information
regarding your trailer and it’s
components.
The law requires that the white ground
wire on both the tongue wire har-
ness and vehicle harness be prop-
erly grounded to respective trailer and
vehicle frames.
