Exhaust elbow angle (a) relative to water line,
fig. A should be min 15° (26%).
The silencer should be fitted as close to the engine as
possible. The hose must be arranged with a continuos
inclination into the silencer throughout the whole dis-
tance, see fig. A.
NOTE! The minimun distance (H) between the engine
exhaust centerline and the silencer inlet center should
be 150 mm (6").
Length (A) Height min. (H)

If the hose between elbow and silencer has such a
length or design it must be supported (1) to avoid a
"sack", see figure A.
