Propeller
For best performance and fuel economy, engine rpm
must be kept within the maximum revolution range;
refer to the Technical Data page 112 section. If max-
imum engine rpm exceeds the maximum recom-
mended engine rpm the propeller must be replaced.
Damaged propellers must be replaced as soon as pos-
sible. If a boat must be driven with a damaged propeller
it must be done with extreme caution and only at
reduced rpm.
