Abstract: A trim tab control apparatus includes a switch housing that mounts to the lever of a throttle of a boat. The switch housing provides a socket that holds a dual trim tab switch arrangement in front of and below the handle of the throttle. This enables a pilot of a boat to operate either or both of the switches that control the port and starboard trim tabs. The pilot of the boat can operate either trim tab by depressing a selected of the switches or both trim tabs can be raised or lowered at the same time by operating both switches at the same time with one finger, wherein typically only the index finger of the pilot is required. The apparatus of the invention enables the operator of a boat to operate both port and starboard trim tabs without even having to view the switches because they are in such close proximity to the user's index finger while the pilot is driving the boat, holding onto the throttle.
