Step Procedure
Tank Band Assembly
Fig. E 3.1 Temporarily move Tank Bands [10] slightly to the center of the tanks, to allow
application of Tar Strips.
3.2 Tar Strips:
a)Tar Strips bond the Upper Tank Bands [10] to the Tanks [1] and prevent the
Tanks from moving within the Bands.
b)Slight contact between Band and Tar Strip will create a bond which may be
separated with a constant pull.
c)Pressed contact between Band and Tar Strip will create a bond which is difficult
to separate -apply constant pull over extended time.
d)Tar Strips are one layer thick -do not fold,twist or wrinkle.
For each Tank Band -Place one 3”x 24” Tar Strip on top of Tank [1] so that it will be
evenly distributed under Upper Tank Band when Band is installed at “Marked /
Aligned” Location.
3.3 Place Upper Tank Bands [10] onto Tar Strips and Tanks [1] matching the “Location
Marks” and “Alignment Marks” referencing the correct position of the Tank Band
upon the Tank.

Tip: For assembly by one person -A) Lift the rear of the Side Channel [14] into
position and temporarily secure it with a 1/2” x 5” bolt (found in parts bag). B)
Raise the front of the Side Channel and attach it loosely to the front cross Channel
[11] using 1/2” x 1-1/2” bolts. C) Returnto the rear of the Side Channel, remove the
5” bolt, and secure using 1/2” x 1-1/2” bolts
4.3 Attach center Cross Channel [11] to Side Channels [14]
Fasteners per Cross Channel: (8 ea.) 1/2” x 1-1/2” bolt, nut & lockwasher with
flatwasher on slotted holes.
Note...
The parts installed in the next steps may have to be moved to better fit the bottom of the boat after it has
been lifted. Accurate measurements of the boat’s hull before assembly and careful attention to these steps
may prevent repositioning the parts over the water.
Positioning...
Fig. F If the boat hull is unable to be measured prior to hoist assembly, space the Hull Support Columns [4-5]
36” to 42” apart at the rear of the hoist, and the front columns 3” narrower than the rear. Typically, the
longer leg of the column [4-5] is positioned vertically to lift the boat higher above the water, however the
shorter leg of the column may be positioned vertically to accommodate a boat with a deeper draft.

Step Procedure
Leveling the Hoist
Fig. A 7.1 Stand at the rear of the hoist and sight from the rear Cross Channel [11] to the front
Cross Channel to make sure the front andrear are parallel and that there is no twist or
warp in the hoist. If one corner appears to be low, place a block under that corner, as
necessary, to align the corners.
7Stand at the side of the hoist and sight across the Side Channels [13 & 14] to make
sure that they are parallel and that there is no twist or warp in the hoist. If one corner
appears to be low, place a block under that corner, as necessary, to align the corners.
Tightening All
Fasteners
Fig. A
7.2 With the unit level, tighten all 3/8” Tank Band [9 & 10] bolts alternating between
paired bolts and with the bolts on the other side of the Tank Band to ensure uniform
pressure on the tank. Proper tightening is achieved when the tank band flanges begin
to deflect and all bolts have equal tension (about 35 ft-lbs. of torque). It is normal for
the metal band to make “popping” noises as it is tightened around the fiberglass
7.3 Tighten all 1/2” bolts to approximately 65 ft.-lbs. of torque. Exception: The 5”
Hull Support bolts previously tightened. Note: When tightening bolts on the frame,
the end plates of the Cross Channels and Weldment Assembly MUST be against the
web of the side Channel -NO GAP should exist between the parts.

Step Procedure
Positioning the Boat
for Lifting 7.1 Pull the boat over the hoist and position the boat's fore/aft Center of Gravity directly
over the CENTER Cross Channel [11] of the hoist frame.(The object is to balance the
boat on the Hoist. Bow heavy position places excessive stress on pivots and
moorings. Stern heavy position inhibits proper lifting.)
Note:
Boats with a center line length longer than 24 feet should not be installed on the
4000 FM.
Boats with a center line length longer than 26 feet should not be installed on the
6000 FM.
7.2 With the boat in the proper position, and centered port & starboard over the lift,
secure Guide Ropes:
1. Tie a small loop (about 6 inches in diameter) in one end of each Guide Rope and
place the loops over the REAR port & starboard cleats of the boat.
2. Pull the Guide Ropes tight and tie the loose ends to the outboard ends of the
Frame Weldment Assembly [12].
3. Attach the Warning Decals (SP34) to the Guide ropes.
Center of Gravity (Varies by boat)
Center Cross Channel

Step Procedure
Lifting the Boat 7.3 Hold the front of the boat centered over the hoist, pushing the boat to stern gently
until the Guide Ropes are taut. The Guide Ropes center the boat's stern over the hoist,
and keep the transom aligned over the Hull Support Pads.
7.4 While continuing to push back gently on the boat and keeping the Guide Ropes taut,
rotate the Control Unit Handle to the Lift/Launch position and turn the switch to ON.
When the hoist makes full contact with the boat, it is no longer necessary to push back
on the boat.
Balance and Load 7.5 As the hoist raises, observe the hoist's operation; the position of the boat on the Hull
Support Pads; Moorings and Dock Brackets, and the Guide Ropes. STOP, LOWER
THE HOIST, AND MAKE ADJUSTMENTS IF NECESSARY.
7.6 With the hoist fully raised, carefully observe the boat's position on the hoist and on the
Hull Support Pads. The boat should be centered side to side, with the hull Support
Pads contacting the hull between the chines and to the transom area.
Note 1: It is common for some unavoidable crossing of the chines at the bow of the
boat, which is acceptable.
Note 2: The ends of the Hull Support Pads should extend to the transom of outboard
boats; for stern-drive boats, the ends of the Hull Support Pads should not extend
forward of the engine compartment. Reposition the boat or pads if necessary.
7.7 Carefully check the hoist's position in the water. The tanks should be level fore to aft
with an acceptable 4 inch drop to stern. Correct the fore to aft position of the boat on
the hoist to correct any imbalance.
7.8 At least 6 inches of each tank should be above the water surface for correct lifting and
hoist stability. If less than 6 inches of the tank is above the water, the boat is too
heavy for the hoist, and a larger hoist should be installed.
