ENGINE
ENlJ
With engine installed and properly
aligned, it must now be supplied
with fuel, '1ater, and electrical
power, and provisions made for ex-
haust. now these elements are to
be installed will depend to some
extent on the model of engine being
used, location of the gas tank, lo-
cation of the instrument panel and
personal preference as to side or
stern exhaust. In any case these
things should be installed in a
workmanlike manner and certain good
practices adhered to.
5. EXHAUST PIPIKG
Exhaust piping should be at least
a~ large as the opening on the ex-
haust mp.nifold. Either copper tubing
or galv2nized pipe may be used. If

elbows are nece'ssary in the 1 ine,
they should never exceed 45 degrees.
A short piece of steam hose (See
Fig. 8) placed in the exhaust line
close to the engine will help quiet
the exhaust and prevent fracture of
exhaust line due to vibration of
the engine. It is common practice
to direct cooling_ uater from the
engine into the exhaust line. In
so doing, two purposes are served:
the hot exhaust line is cooled be-
low the daI.lg~r point and the ~7ater
quiets the ,,-,.:haust. In this type of
installation, two precautions must
be oTJserved. First, the '"Jater must
enter the exhaust no less than 5"
belm'! the bottoD of the manifold
opening and some provision oust be
made to direct the flm'! of 't"later
away
from the manifold. Tbese pro-
visions are necessary to prevent
cooling water from backing up into

the exhaust manifold and perhaps
warping the hot exhaust valves.
There are several types of water·
cooled elbows on the market '7hicb
't7ill serve both of the above pur-
pose~ ~nd are worth their cost in
labor of fabricating a substitute.
Hm1ever, a subst i tute can be made
by welding a steel elbow into the
exhaust line at least 4" bel0'\7 the
exhaust oanifold in such a T,;rf:'.Y that
the uater '7i 11 be directed avray from
the ~anifold. (See Fig. 9)
6. COOLIh'G r,'ATER SYSTEM
1~Tater piping can best be done with
standard copper tubing. Again, a
short piece of flexible hose should
be used between the intake piping
and the engine. The water intake
scoop should be located as close to
the water intake on the engine as
installation permits. Some engines
are equipped with reversing and re-
