The tilt relay solenoid allows the engine to trim down and adjusts the angle of the motor in any bumpy situations for smoother boat operations. Trimming works for the first short distance until the engine goes up to 20 degrees way up and starts tilting until the engine is completely tilted in which lifts the boat up to make way from the sea surface.
