"NEW" |
For
smaller inboard craft, the 3-blade DJ355 offers the best value
for smooth, reliable, and quiet performance. This constant pitch,
zero offset series is low maintenance, but meets the performance
design criteria of a wide range of applications.
In the same design as the 3-blade, the 4-blade DQ469 may be a
more suitable choice for a particular application. Under certain
loading conditions, or where full keels, tunnels, or pockets
affect the water flow to the propeller, a 4-blade may be the
better choice to maximize thrust and minimize noise and vibration.
Both
DJ355 and DQ469 are available in certifiable manganese Bronze or
NiBrAl material. Standard SAE or metric bores are readily available.
"Cupped" trailing edges are available in NiBrAl material.
The DJ355 and DQ469 are hand crafted, carefully inspected, and
balanced to close tolerance. The designs offer exceptional service
life, and contribute to trouble free enjoyment of boating.
