An electronic position monitor (10) and readout device (72, 90) for trim tabs on boats in which the monitor and readout device are connected to the trim tab controls. The device is electronic and position display is based on the time required for trim tab movement. Signals from the trim tab controls produce signals from timers (62, 63) which in turn are directed to enabling circuits (58, 60). If the enabling circuits pass the timer signals, they are counted in counter circuits (44, 46) and thence directed to a decoder (64) and finally to the display panel (72-90). The display panel is arranged to show the precise angular position of the trim tabs to the boat operator. |
