Michigan Wheel 161004 Aluminum 3-Blade Propeller, 21 x 14-3/8 RH, for Volvo Penta SX/SX Cobra & OMC Cobra I/O

The Michigan Wheel 161004 is a cast aluminum, 3-blade boat propeller from the Michigan Match series, built as a durable primary propeller or a reliable spare for sterndrive applications. It measures 21 inches in diameter with a 14-3/8 inch pitch and turns in right-hand rotation. Every Michigan Match propeller uses a naval brass spindle paired with a rubber-cushioned hub that absorbs the impact and stress of shifting gears; the rubber bushing is engineered to spin free under significant impact, which reduces the potential for lower unit damage. The propeller has a powder-coated aluminum finish for corrosion resistance and comes with the hub kit needed for installation.

Michigan Wheel recommends the 161004 for boats in the 17 to 22 foot range running in the 39 to 50 MPH range, making it well suited to inflatables, aluminum consoles, walleye boats, offshore singles, pontoons, ski boats, family cruisers, workboats, and houseboats. It is designed for Volvo Penta SX and SX Cobra, and OMC Cobra I/O drives, with a 4-3/4 inch gearcase, thru-hub exhaust, and 19 tooth spline, covering engines from 3.0 L through 8.2 L. As a genuine Michigan Wheel part carrying MPN 161004, it is a straightforward replacement for a worn, damaged, or mismatched propeller on these drives.
