Several embodiments of automatic trim controls for marine outboard drives for maintaining the optimum trim angle under all running conditions. The velocity of the watercraft is determined and the outboard drive is trimmed up as long as the velocity continues to increase and then is trimmed down so as to maintain the highest velocity possible for a given running condition. Several different computer programs are illustrated and described for achieving this purpose and a number of different embodiments of power units for controlling the trim condition are also described, some hydraulic and other mechanical.
