At HydroHoist®, we take pride in bringing the most advanced, easiest to use, and lowest maintenance boat li sys-
tems to the market. Installaon of the li is simple due to its lightweight design and ease of operaon.
The following pages contain step-by-step instrucons of the installaon and operaon processes.
The heavy series HarborHoist™ li takes 24 man-hours to assemble on average. Review all parts, hardware, and
required tools before beginning assembly. Don’t forget: safety rst.
If you have quesons, contact the Technical Support Team at 1-800-825-3379.
Legend:
Requires careful consideraon
WARNING: could cause harm or damage to the li, vessel, and user
INTRODUCTION
Lis must be installed by an approved HydroHoist® installer. Failure to comply will result in termina-
on of warranty and could cause injury to the user and damage to the li and vessel.
It is STRONGLY recommended that each installer read the manual before aempng an installaon.

PRE-INSTALLATION CONSIDERATIONS
Due to its size, the following determinaons must be made before installing a HarborHoist:
• Locaon of li assembly (remote or on-site)
• If remote then, method of transport from assembly to launch site
• Equipment required to safely build, transport, and launch the li
• Contact points between bunks and the hull (consider strakes and other hull protrusions)
If you plan to build remotely and assemble the li before transport, rst determine the li’s minimum width from
Chart 1. State regulaons may require special permits and escorts for transportaon. Consider how to obtain per-
mits and the cost. Remotely building pre-sub assemblies and then compleng nal assembly at the launch site might
be logiscally simpler.
Other items to consider:
• Does the launch site allow commercial work?
• Do you need a permit to work and/or launch at the ramp or dock?
• Is there a me limit on dock use?
• How will you transport the li from the launch site to the install locaon?
• How much of the li can be preassembled and transported safely?
• Do you have equipment with the capacity to li subassemblies onto a trailer for transport to the launch site?
• Does the nal assembly locaon have equipment to hoist and launch the completed li?
• Is there level ground for nal assembly, or will some assembly occur in the water?
• Verify the slip width meets the minimum requirements of the li width, see Chart 1.
• See Chart 2 for a list of the required tools.
Working through these consideraons is the rst step in a successful build.

**** This assumes you are using a rope mooring soluon. This measurement allows for a 4" space between
the rub rail of the vessel and walkway. If used with a pole mooring system add an addional 24" to the mini-
mum slip width to take into account this system. The addional 24” will allow for mooring on both sides of
the li (12” per side)

STEP 4: ATTACH STRAP PLATE ASSEMBLY TO TANK
1. Roll the tank onto its back for unobstructed access to the top and boom of the tank, as illustrated below.
2. Place the completed Strap Plate Assembly into the recesses along the front and top of the tank.
The next procedure must be followed in order to prevent damage to the tank. DO NOT force the
assembly together as this could cause the nylon bushing to damage the tank.
3. Slide the 1/2 x 13 x 8” Boom Hex Bolt through the Boom Tank Gasket, the loosely assembled tank bracket and
the Top Clamp, as illustrated below.
4. Tighten the Top-Side Bolt Assembly unl snug.
5. Tighten the Boom-Side Bolt Assembly unl snug.
6. Tighten Top-Side Brass Nut to specicaon, drawing the assembly into the recess of the tank. Verify this is com-
pleted to avoid the bolt rotang when assembly the cross beam in a later step.
7. Tighten the Boom-Side Bolt Assembly to specicaon.
IMPORTANT: Verify that the (Top Side) Brass Nut has been ghtened in Step 6 to avoid rotaon when assembling
the Cross Channel in a future step.

1. Reposion the tank in the upright posion.
2. Apply thread sealant to the Stub Tube Recommend Sealants: #2 Permatex, 3M 4200, or Permatex with
PTFE. Sealant must have PTFE. See sealant manufacturer applicaon instrucons.
3. Screw the Stub Tube into the tank ng.
4. Apply Thread Sealant to the elbow and screw into Stub Tube ng. You may need to hold the Stub Tube
ng with a pipe wrench to avoid turning it while screwing in the elbow. As the threads ghten, pay
aenon to the direcon that the elbow /hose is poinng.
• Oen, the li’s hull pad dead rise is shallower than that of the vessel. To increase the dead rise
capability of the li, the Stub Tube may need to be trimmed. See Chart 6 for trimming the Stub
Tube and Chart 7 for spacing hull pads. In combinaon, these will give you the dra of the li
needed for your vessel.
• Be careful not to overshoot the desired alignment since backing o the Stub Tube can cause a
leak path around the ng. The Stub Tube can be hand ghtened such that minimal threads on
the elbow are visible.
REPEAT STEPS 1-5 FOR EACH TANK BEFORE PROCEEDING TO STEP 6.

STEP 6(a): ALIGNING THE TANKS
Side Alignment
1. Align the tanks next to each other, ve on each side, spacing them so the mooring rings are 68.25” apart. You may
want to use the full-length hull support bracket as a straight-edge to align the tanks. The hull support bracket is
used in a later step.
2. Align tanks opposite each other using the rules for minimum beam of li or beam of boat. See Step 6(b) for proper
alignment. Verify the tanks are separated enough to accommodate the cross channel in STEP 6(c).
68.25” 68.25” 68.25” 68.25”
The minimum beam of the li is calculated by adding 34” to the beam of the boat. If the li uses AUX tanks,
the minimum beam of the li maybe determined by the width of the AUX tank. Refer to Table 1.
When sizing the slip this way, it will leave a minimum of a 4IN. gap for each of the lis. Near this width, the
walkway could catch on the edge of the dock while raising or lowering. Dock fenders are recommended to pre-
vent this. See Chart 1 for minimum li widths.

3. Perform Steps 6(b) and (c). Verify equal length diagonals as you build from tank Set 1 to tank.
Set 5 as shown below to ensure they are square.
4. Aer conrming the li is square and all assembly for Steps 6(b) and (c) are completed, ghten all
hardware completely.

STEP 6(b): TANK AND WALKWAY ALIGNMENT AND ATTACHMENT
1. Place the Spacer Tubes between the outside set of U-Bolts on tank Set 1 and Set 5. See Figure B below.
2. Place Span Beams between the U-Bolt sets on the connecng tanks. See Figure C below.
3. Starng with tank Set 3, loosely aach the walkway support on top of the span beam, as illustrated below.
Ensure the U-Bolts are centered in the middle of the walkway slots on the walkway support. As walkway
supports are added to the other tank sets, the U-Bolts will shi outward in the walkway slots. Add walk-
way supports to tank Set 2 and tank Set 4 and then add walkway supports to tank Set 1 and tank Set 5. Thus
working from the middle out. See Figure A.
4. Conrm the Span Beams are centered between the two tanks and the Spacers are in the proper posion.
Wait to ghten all hardware on the walkway unl you have completed Step 6(c).
If you use a Single-Sided Tie-O method for mooring, the Spacer Tubes must be removed in a later step. Do
not ghten the U-Bolts fastening the walkway over the spacers. Refer to STEP 16: TIE-OFF MOORING.

1. Place the Receiver Spacers, two per tank, on the rear bolts that are poinng up. Be sure to place them on
the opposite tank that you are connecng.
2. Connect the facing tanks by placing the Cross Channels on top of the Support Channels between the U-
Bolts. Install the Top Clamp to the tank frame assemblies.
3. Finger-ghten the U-Bolt nuts to hold the Top Clamp in place. Repeat for each set of tanks.
Do not fully ghten unl you verify that Step 6(a), 6(b), and 6(c) have been completed.

STEP 7(a): HULL PAD ALIGNMENT (V-HULL ONLY)
Before installing the hull pads, it is important to determine the bunk spacing: how far apart the hull pads should be
mounted on the cross beams. To calculate the proper spacing, refer to the table below. Consult your boat manufactur-
er for dead rise informaon.
How to Use the Bunk Value Table
The chart shows pad separaon and max dead rise angle to maintain 1” minimum clearance to the cross channel
listed top to boom.
Aligning the Hull Pads
Place the hull pads as wide as possible while maintaining clearance between the hull and I-beam. Be sure to check
the boat, boat trailer, or consult the boat manufacturer to ensure the locaon is clear of underwater obstrucons,
such as speedometer sensors, water pickups, etc. The hull pads can be placed on the li so that the front is narrow-
er than the rear if needed to support sharper dead rises at the bow of the vessel. If you do this, verify that the hull
pad does not cross a stake or other feature on the hull that would result in a concentrated loading condion. The
chart below is based on the dead rise angle and separaon distance and is provided as a starng point only.
IF YOUR VESSELS DEADRISE FALLS IN BETWEEN TWO NUMBERS IN THE CHART. ALWAYS, MOVE TO THE
NARROWER HULL PAD SEPARATION FOR HULL PAD PLACEMENT.
