Abstract
A tilt and trim operating mechanism for a marine outboard drive including a simplified electrical arrangement for operating a reversible electric motor from a DC power source. The circuitry includes four relay switches operated in such a manner as to simplify the cost of the components since four double contact relays can be employed rather than two, three contact relays.
