If required, a second model of the oil filter support is available.
This enables the replacement of the filers when the motor
is rotating. During replacement, cartridges are alternatively
excluded from the lubrication system in order to guarantee
the continuity of the filtering action through the cartridge
which is kept in the circuit (see figure 4). The replacement
method is described in the “use and maintenance” manual.
1. Connecting element - 2. Commutation lever -
3. Lubricating oil filters.
For the cases where it is required to position the filter in a
more accessible place, a connecting element is available. This
enables the bypassing of the filter in coming pipes (see figure
5). In order to guarantee that the correct pressure value is
maintained in the lubrication system during the installing of
remote filters, do as follows:
CAUTION
the filter must be installed in a vertical position.
the point where the filter is screwed to the support
should always be under the connecting point of the adap-
tor on the engine.
o
For a correct preparation, draw a line from the adaptor
connecting point. The angle between this line and the
horizontal surface must be equal to the maximum incli-
nation which the boat can reach on the longitudinal and
transversal axis. The screwing point must be positioned
under this line (see figure n. 5).

Prescriptions
o
Pipes must be adapted to the temperature and pressure
conditions typical of the engine model.
o
The pressure fall in each pipe, including its connection,
must be lower than 0,05 bar at 20°C under maximum
range conditions.
o
The pipes must not touch engine parts and they must
be fixed at least in two intermediate points between the
ends. The lengths of each pipe must not be more than
1200 mm.
o
Tubes must be flexible.
