legs with pads (REF. # 1) and the two side members (REF. # 2 & 3) slide the four leveling
legs into the end upright tubes of the side members. Secure in place with 1/2” x 1” set
screws REF. # 37) Set the side members approximately 90” apart. Make sure the rear
gusset plate is to the outside and the small flat tabs on the bottom side tube are to the
inside.
STEP 2. Find the two bottom cross
bar tubes (REF. # 4) (They’re the
ones with the end plates and channels
welded on.) With the channel facing
to the rear of the lift set them between
the two side members so that the end
plate is up against the end of the tabs
that are welded on the bottom side
tube. Fasten to bottom tube with the
eight square U bolts and flange nuts.
(REF. # 16 & 17) Finger tighten

STEP 3. Locate
the two H shape
lifting arms
(REF. # 5).
Slide a Brass
pivot bushing
(REF. # 18) into
each pivot cap on
the ends of the
lifting arms.
Place the lifting
arm into the
channels of the
bottom cross
tubes and fasten
into place using and 1/2” x 3” clevis pins and 1/2” washers (REF. # 19 & 20). Secure
with pins. (REF. # 21).
STEP 4. Find the lifts top bed member (rec. frame 81” x 86 3/4” (REF. # 6). Set the bed
member pivot channels into the ends of the lifting arms. The pivot channels on the outside
of the bed are toward the front of the lift. Locate the two front pulley brackets, 1/2” x 6
1/2” clevis pins and 1/2” washers (REF. # 13, 22 & 20). On the front corner of the bed,
place a pulley bracket with the pulley sheave toward the outside, in between the corner
angle and the pivot channel. From the corner angle side, slide a 1/2” x 6 1/2” clevis pin
through the angle and the pulley bracket into two 1/2” washers and through the lifting arm
and pivot channel. Place another 1/2” washer over the clevis pin and secure with cotter
pin. (See illustration after STEP 5)
STEP 5. Fasten the rear lifting arms to the back pivot channels of the member with 1/2” x
3” clevis pins, 1/2” washers and cotter pins (REF. # 19, 20 & 21).

STEP 6. Find the winch (REF. # 8) decide what side the winch is going on. The winch is
simply turned over to go either left or right. Bolt the winch to the inside of the front
upright using 3/8” fender washers (REF. # 25) on the tube side and standard 3/8” washers
(REF. # 28) on the winch side. Use 3/8”x 3” bolts. (REF. # 29) Find the lift cable
(REF.NO. 14), thread the plain end of the cable through the hole in the side of the winch
drum.
STEP 7. Locate the two round U bolts (REF. # 23) and the one pulley and chain
assembly (REF. # 24). Place the U-bolt through the chain link and into the two holes
directly below the winch and above the diagonal tube of the side member. Secure the U
bolt with 3/8” fender washers and nylock nuts (REF. # 25 & 26). Only finger tighten nuts
at this time. Place the other U-bolt through the cable thimble (REF. # 27) and secure to
opposite side member in the same manner. Pass the cable through the pulley sheave in the
pulley bracket. Then run the cable up to and through the pulley on the front bed cross tube
across to and through the other pulley. Bring the cable back up to the other U bolt around
the cable thimble and secure with cable clamp. (REF. # 30). Install lift wheel (REF. # 9)
on winch and secure with winch hardware. Turning lift wheel clockwise raise the bed of
the lift 3/4 of the way up.

STEP 8. Find the two front angle braces (REF. # 7) (description 1 1/4” X 1 1/4” X 36”
angle with slotted holes on each end)Bolt the one end to the inside face of the front upright
tube with a 3/8” x 3” bolt, washer and nut. (REF. # 29, 28 & 31) Bolt the other end to the
side of the bottom cross tube using the same size bolt, washer and nuts. Tighten up bottom
cross member nut first so that the slot is about in the middle of the bolt. Check front
upright for straightness. Adjust upright if necessary and tighten bolt in upright tube
STEP 9. Take the two stop chains (REF. # 32) and bolt the one end to the bottom side of
the diagonal brace tube of the side member using a 3/8” x 3” bolt (REF. # 29) Place the
chain link between two 3/8” washers and secure with a 3/8” nylock nut (REF. # 28 & 26
). Tighten enough so that the nylock nut is fully engaged with the thread of the bolt, yet
chain should still turn freely. Fasten the other end of the chain to the inside of the bottom
corner of the angle of the top bed cross tube with a 3/8” x 1 1/2” bolt, washers and nylock
nut. (REF. # 33, 28 & 26) Again tighten the nylock nut so that the nylon of the nut is
engaged with the threads of the bolt, but the chain can still turn freely.

LIFT WARNING SHEET
IMPORTANT BOAT LIFT SAFEGUARDS
The boat lift system must be assembled, installed and operated correctly or mechanical failure
causing injury or death may occur. Be sure that all persons operating the lift are familiar with the
correct operating procedures and safety guidelines.
CAUTION - Keep all body parts inside the boat when entering or exiting the boat lift. Do not try to
manually guide the boat into position.
CAUTION – Keep clear of chains, cables, and all moving parts when operating the lift.
CAUTION – On lifts that have a chain drive winch, the cover must be in place while operating.
CAUTION – Never allow anyone to swim around or climb on the lift structure at any time.
CAUTION – Do not operate the lift with people inside the boat.
CAUTION – Never exceed the rated capacity of the lift as this may cause excessive damage to the lift.
Do not allow people to sit in a boat that is on the lift as this may cause to lifts capacity to be exceeded. An
uncovered boat can fill up with water and cause the capacity of the lift to be exceeded.
CAUTION – Before any adjustments are made to the lift, or any work is done, the boat must be removed
and the bed must be fully lowered.
CAUTION – Winches are pre set from the manufacturer and do not need adjusting.
CAUTION – If using a winch with a remote control, the operator must be close enough to the lift to be
sure that no one is around or on the lift, and to be sure that the lift is operating properly
CAUTION - After installation the lift must be leveled in order to operate properly. If the lift is not
leveled properly there will be excessive stress on isolated areas causing failure or damage to the lift.
Before installing the lift each year inspect the cables, pulleys, and all moving parts for wear. Immediately
replace any part that has excessive wear. Check the brake pad in the winch, if it is worn down to 1/16”
thick, cracked, or glazed over, replace it immediately. Check all the bolts to make sure they are tight. On
vertical lifts the cables may stretch and will need to be tightened so there is equal tension on all the cables.
