Before You Buy
The FX-1 control board was used by many marine manufacturers over the years. All boards have a bar-coded serial number starting with 370. Additionally, the board had a white silkscreen PCB-370 written on it. All boards use a nine-pin terminal block, an 8-pin and two six-pin jacks, and a pressure switch jack. Except for the change to surface mount technology, it has not changed in over 25 years of production. The board measures (7 x 3 3/4) and is a direct replacement for systems containing any version of this board.
