4J4: Engine Operating Parameters
The following parameters are estimated based upon parameters from Caterpillar.
RPM Speed Fuel Consumption Naut. Miles/Gallon
1200 6.0 Knots 3.5 GPH 1.72
1500 7.5 5.0 GPH 1.50
1800 10.0 8.5 GPH 1.17
2000 10.5 12.0 GPH .88
2400 11.5 16.5 GPH .70
4J5: Engine Synchronizer
The Glendinning Synchronizer located in the engine room overhead
automatically, exactly synchronizes the engine speeds. The port
engine is the “Slave” and follows the starboard throttle (the “lead”
engine).
To engage the synchronizer:
1) Set the engines to approximately the same speed, higher than idle;
2) Pull the switch on the engine alarm panel (the pilot light will go on);
3) Push the port engine (slave) throttle control all the way forward (This will save
stress on the synchronizer as it adjusts the slave engine’s speed).
You now control the speed of both engines with the starboard “Lead” engine.
To disengage the synchronizer:
1) Pull back “slave” lever until you feel resistance;
2) Push in the switch. The engine throttles are now once again independent.
Note: The synchronizer will automatically disengage if an engine
cannot be synchronized; For this reason, it cannot reliably be used if
both engines are throttled back to idle.
