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 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. 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.
The rear cross member is adjustable forward or backward on
the B & R series trailers to allow the trailer to be adjusted to
various length boats. This is accomplished by removing the
pivot bolts that holds the rear pivot arm to the side frame.
Once the rear pivot arm assembly is loose, reposition in the
new location. Secure in place using the two pivot bolts
removed earlier. Tighten.
The wire harness for the three-light identification light must
be repositioned to a new hole location in the frame to
eliminate any slack and sagging in the wire.
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.
REAR SUPPORT SYSTEM
Bunks (V & B Series)
The bunks must be positioned far enough apart to give your
boat as much stability as possible while transporting. Posi-
tion 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.
FRONT SUPPORT SYSTEM
Bunk
The front bunks should be adjusted either in or out so that
the bunk will continue to run just to the outside of the strake
of the boat. Adjust the bunks up so that there is approximately
1” clearance between the keel of the boat and the center
cross member pad.
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 Detail K, Page 6.)
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 froward 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. Double check your boat
for fit. If desired fit has been achieved, tighten all fasten-
ers 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.
