Introduction to B-Model
The first objective when building a HydroHoist B-Model lift is to become acquainted with the different configurations and
sizes. An example of the nomenclature of the B-Model lifts would be BL-09-2AF-2T-STD. The descriptions for these abbreviations
are as follows.
•
BL = Abbreviation for B-Model Lifts
•
09 = Capacity of Lift in 1000’s of lbs. B-Models come in 9000,12000,15000,17000 lb capacities
•
2AF = Signifies how many adjustable frames the lift has. B-Models can be 2 or 3 adjustable frames depending on size and hull
pad configuration
•
2T = Signifies how many tanks the lift has. B-Models come in 2T and 4T configurations
•
STD = Denotes frame width. There is STD = standard. WD = wide, and XWD = extra wide.
Other examples of commonly used abbreviations are:
•
HP = Hull Pads

Manual Walkthrough
This Installation Manual will guide you through the steps taken to successfully install a B-Model lift. The illustrations are
done in such a way to show how the component being discussed is installed and may not reflect exactly the lift you are installing.
For instance, all of the details in Fig C1-2AF-2T-WD Exploded apply to all lifts but the hull support shown is used in 9000 and
12000 B-Models. The illustration in Fig C2-3AF-4T-XWD Exploded show the hull support that is used on 15000 and 17000 B-
Models. This is one example of how you will have to be able distinguish which illustrations apply to the lift that you are installing
and which illustrations do not. Figures D1-D4 show the most common configurations for each lift to try and clear up any ambigui-
ties that there may be. Also, the optional Centering Guides and Counterweight are left out of the assembly illustrations and are
shown at the end of the Section 6-Assembly.
Important Notice
The Tank Band Settings given in this manual are generic. The distances between any frames with hull pads attached must
be maintained but freedom is given on 3 frame lifts for the front frame placement if another position better suits the boat. Flexibility
is also given for the positioning of the tanks relative to the frames. This dimension should be specific to the boat being lifted. In
general a boats center of gravity (Cg) is approximately 1/3 of the total length. So on a 36’ boat its Cg would be 12’ from the tran-
som. In some cases, such as multiple engine configurations, the Cg is shifted further towards the transom. In these cases the Cg is
usually 1/4 of the total length. So a 40’ multiple engine boat would have a Cg approximately 10’ from the transom. These equations
should be applied to the specific boat being lifted and the Tank Band Settings should be adjusted accordingly. On two tank lifts this
is easily done by verifying that the center of the tanks is aligned with where the approximate Cg of the boat will be when it is posi-
tioned on the lift. The 4T lifts are more difficult but the smaller tanks stay fixed relative to the frames so the outer tanks are the ones
that need to be adjusted to fit the boat. The settings given on a 15B are for a boat with a Cg of 8’ and the settings given for the 17B
are for a boat with a Cg of 9’. Using this information adjust the tank band dimensions “A” accordingly to fit the specific boat being
lifted. It is very difficult to adjust this dimension after the lift is installed so be sure to think these steps through before tightening the
tank bands.
