STARTING THE ENGINE & RUNNING-IN ('Breaking-in)
The somewhat violent changes of hull attitude
that occur in running, combined with the fact
that, in boats the fuel tank is often located
some distance from the carburetor, means
that fuel 'head' at the carburettor can vary
and upset running.
Therefore,it is recommended that a muffler
pressurized fuel feed system be used.
PRESSURIZED FUEL SYSTEM
!
Before starting the engine, always check
the tightness of all the screws and nuts
especially those of joint and movable
parts such as throttle arm. Missing
retightening the loose screws and nuts
often causes the parts breakage that is
capable of harming you.
The following procedure is suitable for these
engines when the fuel containing up to 30%
nitromethane are used.
Fill the tank completely with fuel.
