Other Things to Remember
Absolute cleanliness is required when installing the fuel line. As fuel line material 1/4 in. Plastic
hose may be used (check local requirements and with insurance company, if acceptable). The
ignition cables must not touch the hot engine parts as this may damage insulation. If the engine is
installed in a confined space (e.g., a sailboat) adequate ventilation has to be provided (fire hazard).
Battery is to be installed in a well ventilated space which is protected against moisture and
preferably insulated. The battery is to be fastened securely. Electric equipment and wiring are to
be installed so that vibration and moisture cannot cause malfunction.
The electric wiring diagram is shown in Figure 5.
FUEL AND RUNNING
Fuels
Any regular grade of gasoline may be used (preferably 92 oct.). The gasoline should always be
mixed with two-stroke engine oil mixture: 3 to 3.5% (1/4 pint) of oil to one gallon of gasoline or
1/4 pinto of oil, 1-2/5 pints of gasoline and the rest of the gallon kerosene. Starting, however,
requires gasoline-oil mixture. More soot will form when using a mixture of kerosene-gasoline-oil,
as opposed to a mixture of gasoline.
Starting
Refer to
A
Maintenance - Beginning of the boating season
@
page and the starting checks are as
follows:
1. Check fuel level in tank
2. Check that the gear lever is in neutral.
3. Turn on the fuel cock. When a mobile tank is used, prime the carburetor by operating hand
pump until definite resistance is felt.
4. Move the choke lever into a vertical position.
5. Open the throttle approximately one third.
6. Start the engine by turning the ignition key. (Manual Start - Wind the starting rope evenly but
vigorously until free.)
7. After the engine has fired, remove the choke gradually and adjust engine RPM.
8. If exhaust gas cooling has been installed as shown in Figure 4. C, open the cooling valve cock
sufficiently to change all water entering the exhaust pipe into steam. The cock has been
sufficiently opened when exhaust gases are accompanied by steam only and no water drops.
Starting (warm engine)
The starting operation is conducted as above with the exception that no choke is to be used.
If for some reason the choke has been used, and the engine does not fire, proceed as follows:
Make sure that the choke is not on, open the throttle fully and turn the engine a few times. After
the engine has started, adjust RPM. The best way to ensure firing of a very warm engine is to
have the throttle fully opened.
