IMCO Standard Height Extension Box Only

This is the most advanced, easy to install, state of the art standardbox on the market today. The torsional drive shaft helps cushion theshock to the outdrive when shifting in and out of gear, and on and offthrottle operations. Inferior designed competitor’s boxes use a drive shaftthat is solid mounted to the flywheel, doing away with your coupler.Their units literally hammer the internal components in your drive,which rapidly accelerates failure.

IMCO’s torsional driveshaft and the stock MerCruiser rubbercoupler are designed to absorb shock resulting from extreme highperformance applications and rough water conditions.
