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 placed
on it. Best towing is achieved when the tongue weight is 5-
7% of the total gross load of the complete unit.
NOTE: The wire harness will need care when moving the
assembly.
Rear Support System
Place the boat on the trailer. 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.
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 the strake. The rollers need to be
adjusted so that you have a minimum of 1” to 2” of clearance
between the keel of the boat and the cross member pad. 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 Support System
Roller
The keel of the boat must rest on the front keel roller system
creating a three-point support system. The keel roller system
is designed to fit most boats without further adjustment,
however there is considerable difference between boat
bottom designs and certain lines of boats will require the front
cross member to be adjusted up from its normal shipping
position which is the down position.
Determine how high the front cross member will have to be
raised to fit the boat. Note that the front cross member can be
adjusted in four different heights ranging from its down
position to a position where the cross member is flat. Loosen
the two 3/8” X 5” carriage bolts located at the outer end of the
channels of the front roller assembly. (See Page 5) Remove
the two 3/8” X 3” carriage bolts attaching the center support channel to the front cross member. Raise the complete
assembly up. Align the desired holes in the center support
channel with the holes in the cross frame. Reinsert the two
bolts just removed. Place on the lock nuts removed.
Tighten. Tighten the nuts again on the two bolts loosened
at the ends of the channels of the front roller assembly.
Adjustment is complete.
Winch Post Adjustment
Slide the winch post assembly back towards the boat. The
bow stop roller needs to be located directly above the boat
bow eye to prevent your boat from moving forward in the
event of a sudden stop.
Note that the outer winch base has several holes of
adjustment. Changing the bolt location will change the
angle of the winch post and will raise or lower the height of
the bow roller. Choose the bolt location which best
matches it to the bow eye height. The inner and outer
winch post channels can telescope either in or out with
respect to each other to lengthen or shorten the overall
length of the post. Loosen the two bolts located on the
back, inside of the channels. Attach the winch strap into
the bow eye and crank the winch strap in until the bow eye
is located in it’s proper position just above the bow eye.
Slide the inner post in or out to a desired length.
Once the bow stop roller is located in it’s proper position
above the bow eye, tighten the bolts that secure the
assembly to the tongue.
Attach the bow eye safety chain into the bow eye as well.
This is another level of protection to keep your trailer and
boat together as one unit. It may be used to keep your
boat on the trailer while loading and unloading at the ramp,
especially with a roller trailer.
Adjustments are now complete.
D ouble 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.
See your ShoreLand’r Owner’s Guide for further
technical information regarding your trailer and its
components.
