  • Patent number: 5171172
    Abstract: An automatic trim assembly (10) adjusts the trim of an engine (14) in a boat (12) based upon the speed of the boat (12). A pressure switch (18) senses the speed of the boat from a pitot tube and switches to a first condition when the speed is below a predetermined speed and to a second condition when the speed is above the predetermined speed. A control circuit (16) trims the engine (14) to a first or low position in response to the switch (18) being in the first condition, and trims the engine (14) to a second or high position in response to the switch (18) being in the second condition. An initiation circuit (62) is provided to automatically trim the engine (14) to the first position upon start-up of the assembly (10). An inhibit circuit (64) prevents trimming of the engine (14) to the first position when the speed of the boat exceeds the predetermined speed upon start-up of the assembly (10).
