Final Assembly Instructions
Remove the small parts from the frame by cutting the bands. Re-
move the bolt bag and sort all nuts and bolts by size.
Refer to the individual pages for assembly instruction by bundles.
Reference: Standing at the rear of the trailer will determine the
right and left side of the trailer in the assembly instructions.
The SLB150T side frames and crossmembers are assembled at
the manufacturer. The spring brackets and fenders are also as-
sembled at the manufacturer.
Cautions and Warnings:
The law requires that the white ground wire on both the tongue wire
harness and vehicle harness be properly grounded to the respec-
tive trailer and vehicle frames.
Check all nuts and bolts; tighten before towing.
Tongue Weight Adjustment:
Tongue weight should be 5% to 7% of the total gross weight of the
boat and trailer combined.
Tongue weight too high, move the axle assembly forward.
Tongue weight too low, move the axle assembly backward.
NOTE: Brake line and wire harness will need care when moving
the assembly.
Adjustments
Winch Post:
Place the boat on the trailer and position it for proper support. Once
the boat is positioned adjust the winch post as follows:
Loosen the U-bolts attaching the winch post mounting bases to the
tongue. Rotate the winch post assembly either upward or down-
ward until the strap coming off the winch is at the same height as
the boat bow eye. Slide the assembly backward until the bow eye
roller about contacts the boat. Place the retainer strap up over the
top of the boat bow eye. Note that the bow roller assembly may
have to be adjusted either up or down on the winch post pivot tube
so that the retainer strap is directly above the boat bow eye as the
bow roller contacts the boat. This is a good starting point for the fine
adjustment of he winch post as described below.
Winch Strap Adjusting Instructions:
Route the winch strap through the loop in the end of the winch post
retainer strap, then attach into the boat bow eye. Winch the boat on
the trailer until the boat is just touching the bow roller of the winch
post assembly. Loosen the bow roller assembly and either raise or
lower until the loop in the winch post retainer strap is positioned on
the top of the boat bow eye. Re-tighten in new position. Winch the
boat securely on the trailer.
Proper adjustment is when the bow roller is in contact with the boat
and the winch post retainer strap is securely pulled onto the top of
the boat bow eye at the same time.
Note that they must both make contact at the same time to create
the maximum retaining force of the boat propelling forward in the
event of a panic or sudden stop.
Once the above adjustment is accomplished, hook the bow eye
safety chain into the boat bow eye as extra security to keep the
boat from sliding off the back of the trailer in the event that the
winch fails.
Rear Support System:
Place the boat on the trailer so that the transom is located at the
rear of the support system. On an 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 two bolts that attach the ends of the rear
cross member to each side frame. Slide the assembly to another
set of holes provided in the side frames that is more desirable, and
then re-attach the cross member in the new location with the bolts
just removed.
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 a strake 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 one to two
inches of clearance is desirable.
Front Support System
Bunk
The front bunks should be adjusted either in or out so that the bunk
will run just to the outside of the strake of the boat. The bunks can
be adjusted either farther in or out from the location of the rear
bunk position. Adjust the bunks up so that there is approximately
1” clearance between the keel of the boat and the center cross
member pad.
Read your ShoreLand’r Owner’s Guide and all safety decals on
the trailer.
Wash and wax your trailer regularly. Always rinse your trailer after
each use, especially when boating in salt or brackish water.
Re-check all fasteners for tightness before towing.
Check the tire pressure before towing.
Contact your authorized ShoreLand’r dealer if you experience a
problem with your trailer.
