V-SERIES BUNK ASSEMBLY

Position the bunks onto the brackets already installed to the

cross members. Attach the bunks to the bunk brackets us-

ing 3/8” x 1” hex bolts and hex ﬂange lock nuts.

The 3/8” bolts just installed can be tightened but not over

tightened because the bunks should be allowed to rotate

slightly to conform to the boat bottom once the boat is set

on the trailer.

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 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.

Note: Wire harnesses and brake line lines (if equipped with

brakes) will need care when moving the axle assembly.

REAR SUPPORT SYSTEM

1. 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. 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 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

removed. Tighten.

The wire harness for the three-light identiﬁcation light must be

repositioned where it comes from the side frame to the rear

pivot to eliminate slack, and sagging of the wiring.

2. 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 rest-

ing on the center pads. A minimum of one to two inches of

clearance is desirable.

FRONT SUPPORT SYSTEM

1. 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 center line of the trailer. 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

1. 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 ﬁt your

boat. Once in this position, align the closest pair of holes in

the brackets and reinsert the bolt just removed. Tighten. At-

tach 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.

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.

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 check before towing.

See your ShoreLand’r Owner’s Guide for further technical

information regarding your trailer and its components.
