PROPELLER SLIPPAGE
Slippage depends on vessel weight, number of engines, propeller surface area and
number of blades.
Slip examples
Light weight high speed vessel average 10-15% slip. Using 15.5 – 16” diameter
propellers.
Heavy medium speed vessel 3-3.5 ton per engine 10-20% slip. Using 15.5 – 17”
diameter propellers.
PROPELLER TESTING AND OPTIMISATION
Choose a propeller for your boating application that will allow the engine to
operate within the specified full throttle operating range. When operating the boat
at full throttle under normal load conditions, the engine RPM should be in the
upper half of the recommended full throttle RPM range. Refer to
Specifications
.
If engine RPM is above that range, select a propeller of increased pitch in order
to reduce engine RPM. If engine RPM is below the recommended range, select a
propeller of reduced pitch to increase engine RPM.
A target of 4,200 rpm +/- 100 rpm at W.O.T during full loaded conditions. This may
need to be adjusted if vessel conditions change.
Diameters between 15.5” and 16” have proven to be the best overall performing
with the OXE diesel outboard.
17-21” pitch have proven to be the best high speed.
13-18” pitch have proven to be the best low speed heavy load performing.
