Propeller selection,
DP-S drive
Propellers for the DP-S drive are classified together
and are marked with a type designation (size code
for size and pitch). D0-D7 for aluminum propellers
and F4-F9 for stainless propellers.
IMPORTANT! The propellers on a DP-S drive
must have the same designation, i.e. the same
diameter and pitch. The part numbers differ, ho-
wever, since one propeller is for left-hand rota-
tion and the other one is for right-hand rotation.
In twin installations, both drives must have pro-
pellers with the same type designation.
IMPORTANT! D-series aluminium propeller
sets used on Duo Prop applications, are not re-
commended for use on boat and engine combi-
nations that are capable of speeds in excess of
35 knots. E-series stainless steel propeller sets
should be used in these applications.
Propeller identification,
DP-S drive
The type designation (A) and the FRONT and REAR
identification (B) are stamped on the end of the pro-
peller hubs. When replacement of the propeller is re-
quired, either a forward or rear propeller can be pur-
chased to maintain the matched set. Always order
replacement propellers by the part number.
Propeller care
A damaged or unbalanced propeller will cause ex-
cessive vibration and a loss of boat speed. Under
these conditions stop the engine and check the pro-
peller for damage. If the propeller appears damaged,
have it checked by your local Volvo Penta dealer. Al-
ways carry a spare propeller and replace the dama-
ged propeller as soon as possible.
NOTE! Never continuously run with a damaged
propeller. Running with a damaged propeller can
result in drive unit and engine damage.
