Parts Desk Insights
The CMX07 covers the 1-1/2" shaft diameter — a size found on larger single-screw inboards, twin-screw cruisers, and some commercial vessels. It’s a less frequently stocked size at local marine retailers, so ordering ahead of a haulout is a good habit. Always measure your shaft diameter with calipers before ordering — the 1-1/2" CMX07 is a distinct size from the 1-3/8" CMX06 and the 1-3/4" CMX08.
For brackish or mixed-salinity water, the CMX07AL aluminum version is the better choice over zinc. For freshwater, use the CMX07M magnesium version.
