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 poten-

tial 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 be-

cause 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 lines will need care when moving

the axle assembly.

REAR RB SUPPORT SYSTEM

Place the boat on the trailer so that the transom is located 1-2”

from the rear of the bunks. 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 pivot bolt that 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 identication light must be re-

positioned where it comes from the side frame to the rear pivot to

eliminate slack, and sagging of the wiring.

Position the RB bunk assemblies so they are far enough apart to

give your boat stability while transporting. When the desired width

is achieved, move the RB bunk assemblies so that they are just to

the outside of a strake.

The RB bunk assemblies need to be adjusted so that you have a

minimum of one to two inches 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 from moving while the other adjustments

are being made. Final tightening will be done at the end of the ad-

justing process.

FRONT ROLLER SUPPORT SYSTEM

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 sys-

tem is designed to t most boats without needing any further ad-

justment, however there are considerable differences in boat bot-

tom 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 and the keel cradle itself. 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.

Once the height of the roller cradle assembly is established the

stabilizer pads can be adjusted. This is accomplished by sliding the

pad up against the boat bottom by hand. It is not necessary that

they 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 ad-

ditional 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

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 sud-

den 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 re-

quired 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 an-

other level of protection to keep your boat and trailer together as

one unit.

Adjustments are now complete. Double check your boat for t. If the

desired t 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 checked before towing.

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

mation regarding your trailer and its components.
