Interpreting load indication
The reading of the load display can be clarified by the following example, selected at random.
Example 1:
The load indicator shows 37% at a speed of 1720 rpm (75% of rated rpm).
This means:
Because the propeller is only accepting 37% of the maximum possible power at a speed of 1720 rpm, the
engine cannot output more power. A reserve of power of 63% remains available (e.g. for acceleration).
Example 2:
The load indicator shows 80% at a rated speed of 2300 rpm.
This means:
Because the propeller is only accepting 80% of the maximum possible power at an engine speed of 2300
rpm, the engine cannot output more power. A reserve of 20% is available for an increase in propulsion
resistance (e.g. by loading the ship or adapting the propellor).
This does not mean:
The engine is unable to output more than 80% of its power.
