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 line lines 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 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 re-
moved. Tighten.
The wire harness for the three-light identification light must be re-
positioned 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 be-
ing 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 sys-
tem is designed to fit most boats without needing any further ad-
justment. It is a rare occasion when the front roller cradles will have
to be raised. However, due to variances in boat bottoms, the need
may arise that you may need to raise the roller cradle higher to sup-
port the boat properly.
This is accomplished by adding an optional SS1003 riser bracket
that will raise the front roller cradle assembly ¾”. A second kit can
be added to raise the roller system a total of 1 ½”.
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 backward on the tongue until the
bow stop roller comes in contact with the boat. This bow roller must
be positioned directly above the bow eye to prevent your boat from
moving forward in the event of a sudden stop. The bow roller as-
sembly can be moved up or down by loosening the three ½” bolt
securing it to the winch post weldment. Slide the winch and bow
stop roller assembly up or down until the bow roller is just above the
bow eye. Hook the winch strap into the bow eye so it passes under
the bow roller. Tighten the strap with the winch to hold the assembly
in position while the bolts loosened to adjust are retightened.
Tighten the bolts securing the winch post assembly to the tongue.
Hook the bow eye safety chain into the bow eye of the boat. This
is just another level of protection to keep your boat and trailer to-
gether as one unit.
Remove the winch handle during transport to eliminate the possibil-
ity of loosing it.
Adjustments are now complete. Double check your boat fit. If the
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
checked before towing.

mation regarding your trailer and its components.
