CMC 50012 5" Vertical Outboard Motor Extension

The CMC 50012 is a 5-inch vertical extension designed to raise outboard motors higher than standard transom mounting height. Constructed of extruded 6061-T6 aluminum alloy, this heavy-duty extension provides the additional clearance needed for specialized marine applications.

Key Features:

• Allows the motor to be mounted 5" higher than the standard mounting height on the transom
• Essential for conversion from prop to jet drive
• Rated for V-6 and smaller boat engine applications
• Made in the USA by CMC in Duncan, OK
• Dimensions: 5" W x 20-1/2" H when mounted
• Can be used with manual or hydraulic jack plates

Applications:

• Propeller to jet drive conversions requiring proper motor positioning
• Mounting on a hydraulic jack plate to raise the motor higher on shallow running boats equipped with tunnel extensions
• Shallow water operations where additional prop clearance is needed
• Compensating for transom height when using longer shaft motors

This static vertical extension provides a durable, corrosion-resistant solution for boats requiring increased motor height. The aluminum construction ensures strength while maintaining a reasonable weight for installation.
