3. Tools and Instruments
1) Test Propeller
P/N. 3B2-64110-1
Outer diameter : 164mm
Width : 12mm
(Reference value)
Model
Speed at WOT
(Wide Open Throttle) (r/min)
F 4B/5B 4,500 - 5,500
F 6B 5,000 - 6,000
This test propeller has been designed for break-in
operation and load test operation.
The engine speed at WOT varies depending on
the conditions such as the level or water or air
temperature, and thus, the measurement is not
for confirmation or power of the engine.
