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 Light Series HarborHoist™ li takes between 8 to 12 man-hours to assemble on average. Review all parts, hard-
ware, 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
It is wise that the following determinaons be made before installing a HarborHoist:
• Locaon of li assembly (remote or on-site)
• 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.

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)

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. Install underneath gasket with recesses facing top side of tank. Secure with 1/2” stainless steel at washer and
1/2” brass Nyloc Nut
4. Evenly ghten the Brass Nyloc Nuts so that the assembly pulls together without binding. Hold top side of at
head bolts while ghtening the Nyloc nuts.

STEP 5: STUB TUBE INSTALLATION
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 dra is shallower than that of the vessel. To increase the dra 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 el-
bow 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, on each side, spacing them so the mooring rings are 68.25” apart 6600 and
8800 models and 104.68” on the 4400. You may want to use the full-length hull pad as a straight-edge to align
the tanks. The hull pad 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).
The minimum beam of the li is calculated by adding 34IN. to the beam of the boat. If the li uses AUX
tanks, the minimum beam of the li is determined by the width of the AUX tank. Refer to Table 1.
When sizing the li this way, it will leave a minimum of a 4IN. gap between the boat and the walkway on each
side. (See gure above) Dock fenders are recommended to prevent the li from catching on the edge of the
dock while raising or lowering. See Chart 1 for minimum li widths.

STEP 6(b): TANK AND WALKWAY ALIGNMENT AND ATTACHMENT
1. Place the Spacer Tubes between the outside set of U-Bolts on rst and last tank sets. 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 the center tank set (tank set 2 or 3 on 8800), 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 walkway supports from the inner tanks sets to the outer ones with a spacing of 1.75”. 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 may be removed in a later step. Do not
ghten the U-Bolts fastening the walkway over the spacers. Refer to STEP 15: TIE-OFF MOORING.

STEP 7(a): HULL PAD ALIGNMENT (V-HULL ONLY) - Straight Cross Beam
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 cross 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, ns, etc. The hull pads can be placed on the li so that the front
is narrower than the rear if needed. 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.

1. Aer conrming the proper spacing, place the Hull Support Bracket for a Hull Pad to the I-Beam. Hold it
in place with an 18” bar clamp.
2. Mount the Hull Support Bracket to the I-Beam using the U-Bolts, Lock Washers, and Brass Nuts. Drill a
7/16" hole through the Hull Support Bracket to connect the U-Bolts to the Cross Channel.
3. Center the Hull Pad from bow to stern.
4. When placing the Hull Pad, rest it on the Cross Channel against the Hull support bracket. Secure it with an 18”
bar clamp.
5. Drill a 7/16” hole through the Hull Pad under the internal web, and then fasten it to the Hull Support
Bracket using the 4” bolt, a at washer, lock washer, and brass nut.
6. Repeat these steps for the opposite side Hull Pad.
