Propellers
For best performance and fuel economy the engine speed should be within the wide open throttle (WOT) range:
See chapter “
Operation”. If the engine speed at wide open throttle (WOT) falls outside the WOT range then the
propeller should be changed.
WARNING! immobilize the engine before starting work. Remove the ignition key and turn off the power sup-
ply with the main switch.
The line cutter (DP) has very sharp edges and must be handled with care.
IMPORTANT! Damaged propellers should be replaced immediately. Operating the boat with a damaged pro-
peller should be undertaken with extreme care and only at reduced engine speeds.
