T-H Marine CMC 50012 5 Inch Motor Mount Vertical Extension, Up Thru V-6

The T-H Marine CMC 50012 is a 5 inch vertical extension for boat motor mounts, designed to raise the outboard mounting height up to 5 inches above the standard transom mounting position. Its primary use is converting a propeller-driven boat to a jet drive setup. An alternate application is mounting the extension onto a hydraulic Power-Lift, allowing shallow-running boats already fitted with a tunnel extension to run the motor higher for improved performance in skinny water.

The CMC 50012 is built from extruded 6061-T6 aluminum alloy, a heavy-gauge material chosen for its resistance to corrosion and long-term durability in marine environments. It operates as a static mount (no moving parts) and is rated for motors up thru V-6. The unit has a 1/2 inch set back and measures 5 inches wide by 20-1/2 inches high when mounted.
