Abstract: A transmission for a stern drive planing power boat having an engine (18) inboard of and adjacent to the stern (16) of the boat and connected through the stern of the boat by means of a universal coupling (32) to a steerable outboard drive leg (30), comprises an epicyclic gearbox (50) mounted inboard on the rear of the engine with at least two alternative selectable gear ratios, and an output shaft (54) connected to the universal coupling. The lowest of the said ratios is a direct drive ratio permanently connected to the output shaft by a one-way clutch (64). Gear change control means may inhibit the selection of a higher gear ratio below a predetermined engine speed, automatically select the gear ratios in response to engine speed, and/or inhibit the selection of a higher gear when a reverse gear is selected.
