IMPORTANT: All hardware for
your trailer is stainless steel.
It is important that you use an
anti-seize material on the bolt
threads when assembling to
prevent gaulding.

Bunk Assembly (B-Series) - Assemble after the axles and tires are assembled.

The 2 x 6 bunk assemblies with mounting brackets are factory assembled. Place
the end of the bunk with the two brackets on the equiload bunk arm. Secure with a
3/8” x 1” hex bolt and lock nuts through the brackets on the bunk and the ear on
each end of the equiload arm. Repeat on the other end of the arm. (See Detail I.)

Place the other end of the bunk in the bracket and adjustable bracket mounted on
the front cross member. (The adjustable bracket is adjustable in height.) Once the
proper position for the rear cross member is determined, the front of the bunk
attaches to the bracket using two No. 10 x 1-1/4” self tapping screws as shown in
Detail H.

The 3/8” bolts can be tightened, do not over tighten. The bunks should be allowed
to rotate slightly to conform to the boat bottom.

Tongue

The tongue comes shipped positioned backwards in the
frame. Remove the nut and bolt that holds the tongue in place
and discard. Slide the tongue out from it’s shipping position
and re-install in the front tongue channel. Line the holes in
the tongue with the holes in the tongue channel. Secure with
a 1/2” x 4” hex bolt and 1/2” lock nut in the front cross hole.

Remove the wire harness from the rear of the tongue. Place
the wire harness and the brake line through the hole in the
tongue cover plate. (See Detail G). Secure the tongue cover
plate in position with a 1/2” x 1-1/2” hex bolt and 1/2” lock nut.
Tighten. Plug the tongue wire harness ends into the frame
harnesses by matching colors and ends. Push the extra wire
into the rear of the tongue or remove the grommets in the
side frame and place the extra wire in the side frame.
Replace grommets just removed.

White Ground Wire Installation

Place the self-tapping screw provided through the round metal
ring on the white ground wire of the tongue harness located
at the rear of the tongue. Attach the ground wire to the main
frame by driving the screw in the hole provided next to the
tongue channel of the frame. This will assure a positive ground
for the lighting.

Safety Chains

Place 1/2” x 5” hex bolt through a 1/2” flat washer and the
last link of the safety chains. Insert in the hole (bottom front
of the actuator) on the tongue. Place the second chain on the
same bolt that is extending through the other side of the
tongue. Secure with a 1/2” flat washer and hex lock nut.

Brake Line

Locate the brass brake line coupling. Remove the plastic cap
and thread the brake line coming out the rear of the tongue
into one end of the coupling. Bend the line in a smooth gradual
radius being careful not to kink the line. Bend so it can be
mated to the brake line from the side frame. Once aligned,
thread the side frame brake line into the other end of the
coupling. Tighten both lines into the coupling.

Winch Post Assembly

(See Detail J, Page 2). The height that the bow eye is located
on your boat will determine the winch post length required.
Once this is determined, attach the winch base to the tongue
with three 1/2” x 4-1/2” hex bolts and lock nuts.

Align the holes in the Profile 2000 mounting channel with the
holes in the top of the winch base. Attach the front of the
winch head mounting channel to the base with a 1/2” x
4-1/2” hex bolt through the hole closest to the front of the
winch base. Secure with a lock nut. Do not tighten.

The winch head can be rotated either up or down. Identify
the correct hole combination to position the bow eye roller
just above the bow eye of your boat. Secure in position by
placing the bushing as shown in Detail J, Ref #1, inside the
winch base so it aligns with the hole just identified for the
proper adjustment. Insert another 1/2” x 4-1/2” hex bolt
through the determined mounting hole in the mounting
channel and winch base making sure the bolt passes through
the bushing.

Secure with a 1/2” lock nut. Tighten all bolts.

One Axle Brake Installation

Cut the tape securing the brake line hose to the axle. Remove the brass
plug from the port in the brass block on the right brake caliper. Thread in
the male end of the brake hose and tighten. Place the other end of the
hose through the hole in the brake line clip bracket and secure with a hose
clip.

Tire And Wheel Assemblies

Mount the tire and wheel assemblies using the
1/2” fine threaded tapered lug nuts provided.
Tighten to 80-90 ft/lb. of torque using the
rotation pattern as shown in the ShoreLandr’s
Owners Manual.

Remove the plastic cap from the end of the frame brake line. This brake
line is located coming out of the black plastic tube in the side frame by the
axle.

Uncoil the brake line so that it reaches the end of the hose just attached to
the brake line clip bracket. Thread the brake line fitting into the brake line
hose. Tighten. NOTE: All bleeding to the line can be done through the
bleeder on the right caliper.

Fill the actuator reservoir with brake fluid and bleed the line per the
instructions in the Brake Manual. NOTE: The axle is already bled at the
factory during assembly. All bleeding to the line can be done through the
bleeder on the right caliper.

For bleeding instructions see the ShoreLand’r Disc

Brake Manual.

Re-torque the lug nuts after 50 miles of driving
and then periodically thereafter.

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 the trailer and
vehicle frames.

TRAILER ADJUSTMENTS

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

The bunks must be 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 boat’s strake.
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 will 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 strake. The rollers need
to be adjusted so that you have a
minimum 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
determined, tighten only enough to hold
the bunks or rollers from moving while
the other adjustments are being made.
Final tightening will be done at the end
of the adjusting process.

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
strake of the boat. The bunks can run at
an angle rather than parallel with the
centerline of the trailer. Adjust the bunks
up so that there is approximately 1”
clearance between the keel of the boat
and the center cross member pad.

RB & 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 further
adjustment, however there is
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. 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
bracket. The additional riser kit is an

SS1403.

Once the height of the roller cradle
assembly is established the stabilizer
pads can be adjusted. Slide the pad up
against the boat bottom. It is not
necessary that stabilizer pads 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 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

Slide the winch post base backward on
the tongue until the bow roller comes in
contact with the boat. The 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
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.

It may also be used to keep your boat
on the trailer while loading and
unloading at the ramp, especially with a
roller trailer.

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.

Re-check 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.
