This series is globally sourced as the economically advantageous standard series propeller line. The “M” are manufactured to Michigan Wheel Marine tolerance and hub dimensional standards. The material used in manufacture is certifiable to ABS type 2 in manganese bronze, and to ABS in NiBrAl. Hale MRI computerized inspection equipment is utilized in manufacturing and final inspection.
0.56 E.A.R. - Diameter range: 9" - 40"
For smaller inboard craft, the 3 blade DJ355 offers the best value for smooth, reliable, and quiet performance. This skewed, constant pitch, zero offset series meets the performance design criteria of a wide range of applications and is a good alternative to the Michigan Dyna-Jet.
0.70 E.A.R. - Diameter range: 9" - 40"
The four blade DQ469 uses the same blade design as the DJ355. The fourth blade provides additional thrust in diameter constrained applications and can help minimize noise and vibration. Like the DJ355, the DQ469 provides good value for smooth, reliable, and quiet performance and can be considered an alternative to the Michigan Dyna-Quad.
0.86 E.A.R. - Diameter range: 17" - 44"
The 4 blade DQ486 comes into consideration when there is requirement for more blade area than offered by the DQ469, due to loading or diameter restiction. The increased skew also helps minimize noise and vibration in situations with limited tip clearance. The DQ486 can be considered an alternative to the Michigan DQX or the Federal HX-400.
1.06 E.A.R. - Diameter range: 22" - 46"
The 5 blade M-506 is intended for highly loaded applications with very tight diameter constraints. Typically, more blade count will contribute to smooth and quiet operation. The 21 degree skew is ideal for tunnel installations. In pronounced keel applications, the 5 blades in rotation will break the synchronization of 4 blades, and thereby reduce vibration.
0.53 E.A.R. - Diameter range: 9" - 40"
