Propellers
For best performance and fuel economy the engine speed should be within the maximum RPM range: See
chapter
“ Operation ” . If the engine speed at maximum RPM falls outside the max. RPM range then the propeller
should be changed.
WARNING! Make it impossible to start the engine when working on the propellers. Take the starter key
out of the starter switch.
IMPORTANT! Damaged propellers should be replaced immediately. Operating the boat with a damaged
propeller should be undertaken with extreme care and only at reduced engine speeds.
