Greasing And Additions; Gearbox-Oil Change; Adjustment Of Idle; Sacrificial Anode - SELVA MARINE SEA HORSE2,5 Owner's Manual

Greasing and additions

The only part, which must be filled with oil, is the gearbox.
Selva supply the motor already with the oil, which the user will have to
change completely after the first 20 cruising hours
After this change you must check its level every 50 hours and change it
every 100 hours, and anyway each season.

Gearbox-oil change

To change the oil do as follows:
Keep the motor in vertical position.
Place a container to collect the used oil under the gearbox.
Take out the oil-level plug and the oil drain-plug.
They have a different size and after the oil change they must be
replaced in their proper seat.
Wait until the oil has drained completely, (during this operation you must
check, if water or other foreign bodies are to be found in the drained oil.
They are signs of anomalies which must be identified and repaired by
qualified staff, before using the motor again).
Protecting the leaning parts, put the motor horizontally, with the oil-level
plug and the oil drain-plug holes upwards.
Inject the oil into the oil drain-plug hole.
The oil must agree with the characteristics listed in the
greasing chart, and must comply with the quantity pointed out
in the technical detailed list.
Insert and tighten the oil-level plug and the oil drain plug.

The used oil must be given to the proper collecting centers or
to a SELVA service point.

Adjustment of idle.

To adjust the idle speed of the motor, remove the top cowling and act on
the idle regulation screw
(cross side) in the proper area of the intake manifold. By
turning the idle screw clockwise the idle r.p.m. increase, by
turning it counterclockwise the r.p.m. decrease.
By increasing the idle r.p.m. of the motor, the propeller may be
engaged and start turning.

Sacrificial anode.

To protect the motor against electrochemical corrosion, due to the
presence in its structure of many different materials, a sacrificial anode
has been applied.
The anode will be subject to a strong corrosion, so you have to remove the
scales from the surfaces of the anode periodically.
Failure to clean it, will affect its effectiveness.
Do not paint the anode, for this would render it ineffective.
When the corrosion compromise its functionality, you have to replace it.
