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:
Pull the boat on the trailer. As you pull the boat on the trailer
check to make sure the bunks are high enough and close
enough to keep the keel of the boat from hitting the cross
members as it is loaded and unloaded. However, it is very
important that they are spaced as far apart as possible
because the farther they are spaced apart, the more stable
your boat will be on the trailer when towing. Allow the boat to
rest on the front support pad on the tongue and the bunks.
Bunk Adjustment
Once the boat clears the cross members the bunks must be
checked that they are properly spaced between the strakes
on the bottom of the boat. They must be located between the
strakes. If they aren’t, they can be adjusted either in or out by
moving the bunk brackets to a new set of holes provided in
the cross members. The bunks must be spaced equal
distances from the centerline of the trailer. When the proper
location is achieved, tighten the nuts and bolts holding the
bunk brackets to the frame.
Additional Adjustments
The bunks can also be adjusted for height in case additional
clearance is needed for either the cross members or
fenders.
The bunks can be positioned so the extra bunk past the
mounting brackets is either forward or backward. This
adjustment can be used to either obtain proper tongue weight
or else give better support to longer boats.
Front Support Pad
The front support pad can be adjusted anywhere forward or
backward on the tongue to best fit and support your boat. It
can also be adjusted for height in the event you need it
adjusted higher to reach your boat keel. Once adjusted in the
proper location, tighten the mounting bolts and nuts.
Winch Post
Adjust the winch post backward to fit your boat. Note that the
rubber V-block has to be positioned directly above the boat
bow eye. This will give it maximum support and strength
forward in the event of a sudden stop. Attach the winch hook
and strap to the bow eye. Tighten. There will be a slight amount
of down pressure on the front of the boat when adjusted as
described. This is correct adjustment. The height of the rub-
ber V-bow stop can be raised or lowered by removing the
two 3/8” x 1” hex bolts and flange lock nuts that attach it to
the upright winch post. Reposition and secure again using
the 3/8” x 1” hex bolts and flange lock nuts just removed.
When the winch post is in its proper location forward and
backward, tighten the three 3/8” x 4” hex bolts and flange
nuts securing the winch post to the tongue.
Tongue Weight
Position all of the gear that will be transported in the boat in
its normal location. Then check for proper tongue weight. The
tongue weight will vary depending on your total load but should
be in a range of 60 lb. minimum to 100 lb. maximum. TOO
LIGHT OF TONGUE WEIGHT WILL CAUSE YOUR UNIT
TO FISHTAIL WHEN BEING TOWED. If the tongue weight
of your unit does not fall within this range, you must
reposition the boat either forward or backward or else
relocate the gear inside the boat.
The bunks may have to be turned end for end to obtain the
proper tongue weight and still achieve optimum support for
your boat.
Adjustments are now complete. Double 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.
Re-check 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.
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.
See your ShoreLand’r Owner’s Guide for further technical
information regarding your trailer and its components.
