NOTE: All nuts and bolts must be tightened before towing.
TRAILER ADJUSTMENTS
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
assembly 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 place on it. Best towing is
achieved when the tongue weight is 5-7% of the total gross load of the complete unit.
NOTE: Brake line and wire harness will need care when moving the assembly.
Rear Support System
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. 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 each end that holds the rear pivot arm
to the side frame and the rear pivot offset
weldments.
Once the rear pivot arm assembly is
removed, remove the two additional bolts
on each side frame that mount the rear pivot offset weldments to the side frame. Move them to
the desired location and remount to the side frames with the bolts just removed. Reposition the
rear pivot arm between the two rear pivot offset weldments just installed. Secure in place using
the two pivot bolts removed earlier. Tighten. 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
The bunks must be 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 the boat’s
strake. 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 1” to 2” of
clearance is desirable.
Winch Post/Bow-eye
Slide the winch post base backward on the tongue until the bow roller comes in contact with
the boat. The 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 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. Attach the winch strap and crank winch tight. Attach the bow eye safety chain into the
