Boat Fitment
Take care to clear shafts, through hull fittings, chines, etc. The boat
’
s keel must NOT rest on a cross beam
and should clear the beam by at least
1”.
The boat
’
s Center of Gravity (CG) must be in the center of the
lift (unless AUX tanks are used) bow to stern and port to starboard. This evenly distributes the load over
the lift, allowing for maximum lift height and level operation.
For boats with AUX Tanks, the goal is to have the same lifting forces behind the CG of the boat as in front.
To achieve this, ensure there is the same amount of tank forward of the CG of the boat as behind the CG.
For AUX tank lifts, adjust the
8’
long center tanks to accomplish this. Additional adjustment can be made
by shifting the boat fore and aft. The main tanks have a total length of
43’ 4”
for an 8 main
-
tank unit. A
12K lift has an additional
8’
of tank available, and the 15K and 18K have
16’
additional (18K are wider,
deeper tanks). The CG of the boat, when located with the transom at the end of the lift, should never be
forward of the center of the lift. If this occurs, another set of Main Tanks may be needed. If the AUX tank
is completely behind the CG of the boat, moving the tank farther back amplifies the lifting effect of the
rear. If you need to move the AUX tank back farther than the end of the lift, verify that you have enough
space available between the outdrives and the tanks to avoid damage to either.
It is the responsibility of the End User to ensure that:
•
The lift is installed by a certified HydroHoist Installer
•
The lift is operated in a safe manner
•
Regular inspection is performed on the lift components
•
Customer has read and understands all safety and warning labels
No alterations or modifications may be made to HydroHoist equipment without the express written con-
sent of HydroHoist. Re
-
installation, adjusting the bunks, and/or adjusting the tank beam spacing must be
performed to the standards of HydroHoist. It is the obligation of the End User to inform all equipment
operators of the above conditions. Additional Owner Manuals and Safety Warning Decals are available by
request.
