FINAL ASSEMBLY INSTRUCTIONS
Remove all banded items and the hardware bag from the frame.
Remove the parts and sort by size.
TONGUE
Locate the tongue and install by sliding it in the front of the tongue
channel.
Line the holes in the tongue with the holes in the tongue channel.
Install the 1/2” x 4” hex bolt in the front cross hole and secure with
a 1/2” ange lock nut.
Remove the wire harness from the rear of the tongue. Place the
wire harness and the brake hose through the hole provided in the
tongue cover plate.
Secure the tongue cover plate in position with the same 1/2” x 11/2” hex bolt that secures the back on the tongue to the tongue
channel of the frame. Secure with a 1/2” lock nut. Tighten both bolts
just installed.
Plug the tongue wire harness ends into the frame harnesses by
matching colors and ends. Push the extra wire provided into the
rear of the tongue. The wire should be positioned so the only thing
exposed to the outside of the tongue and side frame is the black
wire loom.
TONGUE BRAKE HOSE CONNECTION
Locate the brass brake line coupling. Remove the plastic cap from
the tting on the end of the tongue hose. Thread into one end of the
coupling. Remove the hose from the side frame enough to reach
into the rear of the tongue. Remove the plastic cap from the tting
on the side frame hose, then thread into the other end of the coupling. Tighten.
Push the excess hose back inside the tongue so that the coupling
just installed is located inside the rear of the tongue.
SAFETY CHAINS
Locate the 1/2” x 5” hex bolt. Slip the bolt through a 1/2” at washer,
then place through the last link of one of the safety chains.
Place the bolt with chain attached through the hole provided in the
bottom front of the actuator mount on the tongue. Place the second
chain on the portion of the bolt extending through the other side
of the tongue. Place on another 1/2” at washer and hex lock nut.
Tighten.
RETRACTABLE TIE DOWNS
Locate the two retractable tie downs. Next locate one of the 7/16”
x 1 ½” ne threaded bolts supplied with the retractable tie down.
Insert it into the bottom hole on the retractable tie down so the bolt
is pointing through the back side of the tie down. Insert the bolt
through the hole provided in the taillight bracket just inside the side
frame. Secure with the 7/16” ange lock nut. Tighten.
Repeat the above process on the other tie down.

WINCH POST ASSEMBLY
Your trailer may have come with the jack already installed on the
winch base. However, in the event that it did not, use the following
instructions to attach the jack to the winch base before it is installed
on the tongue.
WINCH POST INSTALLATION
The height that the bow eye is placed in your boat will determine
the length winch post required. Once this is determined, attach the
winch base to the tongue with three 1/2” x 4” carriage bolts and
lock nuts.
Align the holes in the Prole 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 by placing 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.
Note that the winch head can now be rotated either up or down.
Identify the correct hole combination to use to position the bow eye
roller just above the bow eye of your boat. When determined, secure in this position by placing the bushing as shown in Diagram D
inside the winch base so it aligns with the hole just identied 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 as well. Secure
with a 1/2” lock nut. Tighten all bolts.
ASSEMBLY & MOUNTING INSTRUCTIONS
JACK - PROFILE 2000 WINCH BASE
The Prole 2000 winch base used on the 2” x 4” and 2” x 5” frame
trailers is formed so that the jack can be mounted directly to it eliminating the need for other mounting hardware for attaching the jack
to the tongue. The jack required for mounting does not require the

mounting base or any of the original mounting hardware components.
Assemble as follows:
The jack must be mounted to the winch base before it is installed
on the trailer tongue. If the winch base is already mounted on the
tongue, it will have to be removed for the jack installation.
Locate the hardware bag and sort all items by size.
Lay the Prole 2000 winch base on its side so the side that the jack
is going to be mounted on is up.
Place the inside jack spacer on the winch base so the center pro-
trusion ts down into the indent in the winch base.
Position the jack mounting plate so it is centered around the inside
jack spacer just positioned.
Lay the jack retainer plate on top of the jack mounting plate aligning
the holes in it with the holes in the winch base.
Insert the two ½” and 1 ¼” carriage bolts into the holes just aligned
in the jack retainer plate and the winch base. Secure in place with
½” lock washers and hex nuts. Tighten.
Once tightened, rotate the jack through its normal pivoting range to
make sure it is free to travel and is not binding up.
If jack pivots, place it on the tongue and secure in place with the
bolts and hardware provided with the trailer. Complete the assembly of the winch head to the winch base. Assembly is complete.

ROCKER ARMS
Locate the rocker arms (Ref. No. 2 in Diagram E). Note that the
center bushing has a grease zerk in it. Position the rocker arms up
into the center channel welded in the center of the tandem spring
bracket so that the grease zerk is pointing down. Align the holes in
the channel with the rocker arm. Secure in place with a 1/2” x 4-1/2”
hex bolt and lock nut. Tighten. Repeat this process on the other
rocker arm and spring bracket. Grease the rocker at this time by
applying grease through the zerk just discussed.
BRAKE INSTALLATION
Locate the brake hose coming out of a hole in the inside rear of the
right side frame near the axle position. Route the hose over to the
axle and insert it into the larger outer hole in the brake hose mounting bracket. Route it down to the caliper where it will be attached
in the brass block.
Remove the brass plug from the port in the brass block on the right
brake caliper. Thread the brake hose just routed down from the
side frame into the port where the brass plug was just removed.
Tighten.
NOTE: The grease zerk is positioned down so that it is accessible for servicing when needed.
SPRINGS
Position the axles so they are properly aligned with the trailer as
shown in Diagram E. Position the brake axle so that the disc brake
calipers are on the back¬side of the axle. The brake axle must always be mounted as the rear axle to give you the best braking possible. Place the front axle so the holes for routing the brake hose
are to the rear in the event that second axle brakes will be mounted
on the trailer in the future. Place the springs on the topside of the
spring pads welded to the axle. (See Diagram E). Note that the
hook end of the spring must be to the rear of the trailer. Place a
spring clamp on the top center of the spring as shown. Next place
the 1/2” x 6-1/2” U-bolts down over the top of the spring clamp,
spring and axle as shown. Place the spring and axle U-bolt plate
onto the ends of the two U-bolts. Secure with 1/2” lock nuts. Thread
onto the U-bolts but do not tighten securely until the complete unit
is in position on the trailer. Repeat on the other spring.
AXLE
Place one of the spring bracket bushings into the rear of the spring
bracket and secure with a 9/16” x 3 1/4” hex bolt and hex lock nut.
Repeat in other spring bracket.
Position the rear axle under the frame, then hook the hook loop of
the spring around the bushings just installed. Note that if the axle
is positioned too low when trying to hook, the hooks will not hook
around the bushings.
Raise the front of the springs up so they align with the rear hole in
the axle boogie just installed. Attach with 9/16” x 3-1/4” hex bolts
and lock nuts.
Install another spring bracket bushing in the front holes on the rock
arm assemblies. Attach with a 9/16” x 3-1/4” hex bolt and lock nut.
Tighten.
Hook the hook end of the springs mounted to the front axle over
the bushing just installed in the rocker arm assembly. Then swing
the front of the spring up and attach the front mounting hole in the
spring bracket with another 9/16” x 3-1/4” hex bolt and lock nut.
Tighten all axle U-bolts and spring bolts not tightened at this time.

ATTACHING AXLE HOSE TO SPRING PLATE
It is important that the brake hose on each end of the axle be attached to the spring plate to eliminate the loops that are formed in
the hose when it is attached to the calipers. Doing so will eliminate
the possibility of the hose getting caught or damaged while towing.
Locate one of the hose clamps. Spread open the clamp so it can be
slipped around the hose in the loop that is formed under the spring
as it is routed to the caliper. Once in position, squeeze the clamp
back together.
Raise the hose clamp and the loop up until the hose clamp is on top
of the spring bracket raising the loop up so it is on the back side of
the axle. Align the hole in the clamp with the hole in the rear of the
spring bracket between the two U-bolts.
Place a No. 10 at washer on a No. 10 x 1” machine bolt. Insert the
bolt into the clamp, then down through the spring bracket. Place
on another No. 10 at washer and secure with a No. 10 hex nut.
Tighten.
Repeat this process on the other loop on the other end of the axle.

FRAME BRAKE LINE
Place the rubber grommet around the brake hose and insert it
into the hole in the brake hose mounting bracket. The grommet
will protect the hose from abrasion as well as retain it from sliding down while being towed. Enough slack should be left in the
brake hose from the hose mounting clamp and the axle to allow the
axle to move freely without the hose rubbing on the spring or any
other steel part. All additional hose above the brake hose mounting
clamp and the side frame hole can be pushed back into the side
frame for protection from the elements.
In the event that the axle position is at some distance from the hole
in the side frame where the brake hose is routed from, two additional hose mounting clamps and self-tapping screws are provided
to attach the brake hose to the inside of the side frame. Bend the
hose mounting clamps open far enough so the hose can be slid inside the clamp. Once the hose is inside, bend the clamps back shut
so it forms around the brake hose. Position the two clamps on the
inside of the side frame spaced so there is an equal distance between the hole where the brake hose comes out of the side frame
and the brake hose mounting clamp. Using the self-tapping screws,
drill them into the side frame to secure the clamps in place. Tighten
until the screws are fully in. This will grip the brake hose and keep
it from moving.

DUAL AXLE BRAKE INSTALLATION
If your trailer is equipped with dual axle brakes connect the line to
the axle as follows:
Locate the 18” brake line hose for the second axle.
Remove the plastic plug from the port in the brass block on the right
brake caliper. Thread the brake hose male end into the block and
tighten to either 6-8 ft. lb. or 72-96 in. lb. of torque.
DO NOT OVER TIGHTEN Over tightening will cause the brass
block to crack and then leak. Secure the hose to the brake hosemounting bracket with the U-shaped hose clip.

FRAME BRAKE LINE
Place the rubber grommet around the brake hose and insert it
into the hole in the brake hose mounting bracket. The grommet
will protect the hose from abrasion as well as retain it from sliding down while being towed. Enough slack should be left in the
brake hose from the hose mounting clamp and the axle to allow the
axle to move freely without the hose rubbing on the spring or any
other steel part. All additional hose above the brake hose mounting
clamp and the side frame hole can be pushed back into the side
frame for protection from the elements.
Locate the brass tee connector. Screw the male port of the tee into
the brake line hose. Tighten. Next connect the side frame hose into
the top port on the tee. Connect the two axles together using the
42” brake hose supplied. Thread one end of the hose into the brass
tee just installed. Route the line over to the second axle, and insert
it into the larger outer hole in the brake hose mounting bracket.
Route it down to the caliper where it will be attached.
Remove the plug from the port in the brass block on the right brake
caliper. Thread the brake hose just routed down from the side frame
into the port where the plug was just removed. Tighten.
Hand-tighten the tting on the end of the 42” brake hose to the side
tting of the brake caliber.
Attach the axle brake hose to the bottom tting on the brake caliber.
Tighten all hose end ttings with a wrench. Tighten 1/4 turn once
the ares are bottomed out. Repeat on other (left) caliper.
If the connection leaks while bleeding, tighten only enough to stop
the leak.
Over-tightening will permanently damage the are of the brass tting causing the tting to leak.
ATTACHING AXLE HOSE TO SPRING PLATE
It is important that the brake hose on each end of the axle be attached to the spring plate to eliminate the loops that are formed in
the hose when it is attached to the calipers. Doing so will eliminate
the possibility of the hose getting caught or damaged while towing.
In the event that the axle position is at some distance from the hole

inside of the side frame spaced so there is an equal distance between the hole where the brake hose comes out of the side frame
and the brake hose mounting clamp. Using the self-tapping screws,
drill them into the side frame to secure the clamps in place. Tighten
until the screws are fully in. This will grip the brake hose and keep
it from moving.
All bleeding to the line is to be done through the bleeders on
the calipers.
Fill the actuator reservoir with brake uid and bleed the line
per the instructions in the brake manual.
TIRE & RIM ASSEMBLIES
Mount the tire and wheel assemblies using the 1/2” ne threaded
tapered lug nuts provided. Tighten to 85-95 ft/lb. of torque using the
rotation pattern as shown in the ShoreLandr’s Owners Manual.
Re-torque the lug nuts after 50 miles of driving and then periodically thereafter.
Locate one of the hose clamps. Spread open the clamp so it can be
slipped around the hose in the loop that is formed under the spring
as it is routed to the caliper. Once in position, squeeze the clamp
back together.
Raise the hose clamp and the loop up until the hose clamp is on top
of the spring bracket raising the loop up so it is on the back side of
the axle. Align the hole in the clamp with the hole in the rear of the
spring bracket between the two U-bolts.
Place a No. 10 at washer on a No. 10 x 1” machine bolt. Insert the
bolt into the clamp, then down through the spring bracket. Place
on another No. 10 at washer and secure with a No. 10 hex nut.
Tighten.
Repeat this process on the other loop on the other end of the axle.

TRAILER ADJUSTMENTS
tongue.
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.
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. The transom of the boat should be within 1-2” of the end of the bunks.
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 or else
have the strake located between the bunks. The bunk positioning
is a pre-determined position that will work best for your particular
boat.
Once all adjustments are complete and checked, connect to the
tow vehicle to make sure all of the lights are operating properly and
match the tow vehicle.
Re-check 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.
Recommended carrying capacity is based on shipping
weight of the trailer with standard equipment. Adding
optional equipment may decrease the trailer’s carrying
capacity.
Front Support System
Bunk
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
The winch post is pre-adjusted to t the boat. If it does not, use the
following instructions to adjust to properly t your boat.
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 t 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.
Check the boat to make sure it is in the desired location forward
and backward on the trailer. If location is as instructed above, tighten the three bolts in the winch base securing the winch base to the
