. Use extreme caution while operating the engine in
confined areas such as enclosed slips or congest-
ed piers. Operation under such conditions could
easily lead to exhaust gasses (carbon monoxide)

windows, doors and portholes closed.
B. Pitch
Pitch is a measure of helix angle, or angle of attack, of
the rotating blade. Pitch is easily understood if one imag-
ines the propeller rotating through a semisolid such as
butter or jello. The distance the propeller will travel in one
revolutioniscalled“Pitch.” Increasingordecreasingpitch
will also have a direct bearing on engine rpm’s because
of the greater bite taken by the blade with each rotation.

ence. Sleeping while the engine is running is not
recommended. Ifpersonsaresleepingaboardwhile

NEVER operate the propulsion engine while
everyone on-board is sleeping. Fatal carbon
monoxide poisoning can occur.

C. Prop Slip
A. Diameter
When traveling through water a propeller is unable to get
a complete bite because of the fluidity of water. “Prop
Slip” is usually expressed as a percent of the computed
theoretical speed. Fifteen to twenty-five percent prop slip
is common for a sport-type boat operating at cruising
speed.
Diameter is twice the distance from the center of the
prop shaft to the extreme tip of a propeller blade. In-
creasing or decreasing propeller size will have a direct
bearingontherpm’s (revolutionsperminute) anengine
will develop. This is due to the greater amount of pro-
peller blade surface in contact with the water. See Fig-
ure E1.
