2.2 Selecting and Mounting the Propeller

mount the propeller.
Figure 2-1
For NAVY 6.0 Evo, there are two types of propellers are available. Users can select a
proper propeller based on different conditions. For a heavily loaded boat with large
thrust, a low pitch propeller is more appropriate. Inversely, for a lightly loaded boat
with a fast running speed, a high pitch one is preferable.
In the delivery package, there are two sets of propellers, including a low-pitch propel-
ler and a high-pitch propeller. The low-pitch propeller with a larger diameter generates
larger thrust at low speed, while the high-pitch propeller generates proper thrust to
propel boats at high speed. It is recommended to use the high-pitch propeller if the
boat speed can reach 15km/h or above, as the propeller can’t work at full perfor-
mance at low speed. Figure 2-1 displays how to mount a propeller correctly.
