ABSTRACT:
A tilt and trim control system includes a simply-structured control unit that better protects its electrical components from contact with water and other contaminates. The control unit includes a pair of relays mounted onto to a printed circuit board. The board and the relays are potted within a housing. A plurality of wire leads are also attached to the printed circuit board with the connections between the leads and the board also being potted. The control unit is attached to the lower section of a cowling that surrounds an engine of the marine drive. The tilt and trim control system additionally includes a terminal block that is positioned within the cowling. The terminal block connects the control unit to a motor of a tilt and trim mechanism, and is positioned above the control unit on the engine. This position of the terminal block generally isolates the terminal block from water that may lie within the lower section of the cowling. The small size of the terminal block, however, does not interfere with the layout of other engine components.
