The Duoprop, Earlier Model; Changing The Direction Of The Propeller Rotation - Volvo Penta AQUAMATIC 280 Workshop Manual

The Duoprop, earlier model

Check the speed range of the relevant boat and select
the correct propeller. See Propeller recommenda-
tions .
NOTE! The propellers are supplied matched in pairs
and must not be mixed.
Install the propellers as follows: Grease the propeller
shaft and install the fishing line deflector (1) and the
propeller (2). Then install the folding washer (3) and
the nut (4). Tighten the nut in a way that any of the
tabs of the folding washer can be folded into the cor-
responding recesses of the nut. Then install the sec-
ond fishing line deflector (5) and the propeller (6),
which is locked with the nut (7). Insert a washer (8)
on the screw (9) and tighten the screw in the propel-
ler shaft center.
Marking:
The propellers are marked on the hub side with
the part number and a size code from A1 to A10.
Changing the direction of the
propeller rotation
The upper gear is designed in a way it does not have
to be changed if you want to change the propeller ro-
tation.
With the standard rotation – left hand rotating propeller
– the lower gear wheel is operating as 'forward' gear
and the shift rod is located in accordance with "A" on
the picture. With a right hand rotating propeller the up-
per gear wheel is operating as "forward" gear and the
shift rod is located in accordance with "B" on the pic-
ture.
In order to reverse the rotation the shift rod between
the yoke (3) and the lever (1) on the shift mechanism
must be moved as follows:
a) Remove the cover over the shift mechanism.
b) Move the shift rod 2 from position "A" to "B".
NOTE! Changing the direction of rotation by revers-
ing the levers in the control is strictly forbidden. With
a left hand as well as with a right hand rotating pro-
peller, the shift cable movement is "pushing" in posi-
tion "forward". Check and adjust the control in accord-
ance with chapters Checking and adjusting con-
trols , page 127 and Checking the retaining pawl
when test running , page 127!
