For smaller or slower recreational 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 can be considered a good alternative to the Michigan Dyna-Jet.

The four blade DQ469 uses the same blade design as the DJ355. On recreational boats, 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.

The 4 blade DQ486 comes into consideration when there is a requirement for more blade area than offered by the DQ469, due to high blade loading or diameter restriction. The increased skew also helps minimize noise and vibration even with limited tip clearance, a common situation on today’s performance demanding recreational boats. The DQ486 can be considered an alternative to the Michigan DQX or the Federal HX-400.

The 5 blade M-506 is intended for recreational boats with very high blade loading and tight diameter constraints. Typically, more blade count will contribute to smooth and quiet operation. The 30 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.
