A drive for a boat includes a gear case and a propeller rotatably mounted to a front of the gear case. The drive also includes a drive support for mounting the gear case to the boat. The drive support allows at least a portion of the gear case to pivot about a trim axis to adjust the boat's trim. A trim plane is formed as part of, or added to, the gear case between a lower portion of the gear case, usually underwater in use, and an upper portion of the gear case. The trim plane has sufficient exposed lower surface area to apply a downward force on the water to assist trimming of the boat.
