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 for-

ward. To increase the tongue weight, adjust the axle back-

ward.

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

Place the boat on the trailer so that the transom is located at

the rear of the support system. The center of the rear rollers

on the roller rack should be approximately 4” from the tran-

som. This gives you maximum support on the transom.

The rear cross member is adjustable forward or backward

toallow 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 identication light must

be repositioned where it comes from the side frame to the

rear pivot to eliminate slack, and sagging of the wiring.

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 a strake. The rollers 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 rollers from moving while the other adjustments

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

the adjusting 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 system is designed to t most boats without need-

ing any further adjustment, however there are 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 brack-

et. 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 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 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. 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 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.

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

information regarding your trailer and its components.
