Boat Lift Boss™ Installation
Step 1 - Lift Cradle Positioning
Lower the boat lift cradle to its lowest position until there is
no tension on the cable. Secure boat with rope so it doesn’t
float away.
Step 2 - Removing the Wheel &
Braking System
To remove the wheel from the boat lift, first remove the
fastener from the center of the wheel. Turn the wheel
counterclockwise until it unthreads from the winch box.
On most models of winch boxes, the cover from the winch
box needs to be removed to access the ratcheting brake
system.
This is the current braking system on the winch box and
MUST be removed or damage may occur. Boat Lift Boss™
has a built-in braking system.
Unbolt and remove the ratchet pawl (the part that makes
the clicking sound when raising the lift).
Reinstall the winch cover and tighten screws.
Step 3 - Installing Boat Lift Boss™
Apply Loctite® to the threads on the input shaft on the
winch box. Thread the tapered drive shaft to your lift and
hand tighten. Push Boat Lift Boss™ drive on to the tapered
shaft.
Secure by using the 3/8” x 2-3/4” (0.95cm x 6.98cm) bolt,
lock washer and 3/8” x 1-1/4” (0.95cm x 3.17cm) diameter
thick fender washer. Hand tighten with 3/8” (0.95cm)
ratchet and 9/16” (1.42cm) socket to approximately 20 foot
lbs of torque (2.76 kgF)
(Do not over tighten.)
Step 4 - Final Connections & Adjustments
Assemble the two piece lower clamp around the lifts
vertical upright as shown in the illustration using two 3/8”
(0.95cm) bolts, four 3/8” (0.95cm) flat washers and two 3/8”
(0.95cm) lock nuts.
Next, attach the bottom of the long torque arm to the two
piece bracket using one 3/8” x 1-1/4” (0.95cm x 3.17cm)
bolt, two 3/8” (0.95cm) flat washers and 3/8” (0.95cm) lock
nut and attach the top to the Boat Lift Boss™ bracket.
Adjust the two piece bracket up or down to level the Boat
Lift Boss™ housing. Tighten bolts securely.
Reinstall the black rubber plug.
Attention:
At this time it is important to check that lifting can only
be done when the gear head goes in a clockwise direction.
Attempting to lift in a counter-clockwise direction may
unscrew the unit from the winch box, causing serious
damage or injury. If you have questions or do not
understand this procedure -STOP- and call the Boat Lift
Boss™ Service Department at 651-357-1862 between 8:00
A.M. and 5:00 P.M. Central Standard Time, Monday - Friday
or e-mail [email protected].
After all connections use
a 10 mm wrench to adjust
and straighten if necessary.

• Do not overload the capacity of the lift or drive system.
When lifting, do not let the cradle or pulleys make contact
with the lift frame. Serious damage or injury could occur.
• Wait for the motor to come to a complete stop before
changing directions.
• When lowering the lift, go down just far enough so the boat
will come off of the lift. Running the system too long in the
down cycle will wind the cable backwards and lift the boat,
which could cause serious damage or injury.

All 120 Volt Boat Lift Boss™ units must only be used on an
electrical circuit which has ground fault interrupter protection.
The interrupter and its supply circuit MUST be installed to
local and state electrical codes. The supply circuit needs to be
properly sized for the correct length of run and requirements.
In low voltage situations a buck boost transformer can be used
to increase voltage. Contact a licensed electrical contractor
for correct installation. Failure to wire properly and or install
ground fault interrupter puts user at high risk of injury or
death.
