Seachest Specifications; Electric Hoist Installation; Calculate Length Of Soundome Tube - Wesmar HD825 Series Operation And Installation Manual

Seachest Specifications

The HD825, depending on the model, will have
a 6-inch or an 8-inch soundome. The size of the
soundome will determine the pipe and the flange
specifications. Use one of the included drawings
when fabricating the seachest at the boat yard.
Steel and wooden boats use steel. Aluminum boats
use aluminum. Fiberglass boats use fiberglass.
Fiberglass seachest with flange can be ordered
from WESMAR. (6-inch Part #62.04327.0 or
8-inch Part #62.04329.0)
6-inch Seachest
1. Use 6-inch schedule 80 steel pipe
(5.761 ID nominal)
2. Length between minimum length (3.2.1)
and 40 in (1.2 m)
3. Paint inside with same bottom paint as hull.
8-inch seachest
1. Use 8-inch Schedule 80 steel pipe
(7.625 in ID nominal)
2. Length between minimum (3.2.1)
and 40 in (1.2 m)
3. Paint inside with same bottom paint as hull.
ELECTRIC HOIST
INSTALLATION
Note: The HD825 can be ordered with an electrical
hoist or a hydraulic hoist.
Calculate Length of Soundome
Tube
There are two electrical hoist systems. One for
the 6-inch soundome and another for the 8-inch
soundome. The difference between the two is the
size of the flange and the total travel.
1. 6-inch soundome: measure the length of the
seachest and add 4 inches (10 cm)
2. 8-inch soundome: measure the length of the
seachest and add 5.5 inches (14 cm)
