Front 67

Reduction Gears--connection

Back 67

Connected to the Reduction gear via the cardan shaft

Front 68

Reduction Gears--Steering Nozzles

Back 68

The steering nozzles are controlled by the Vector Control System and powered by hydraulics. They have a max range of 30 degrees port and starboard.

Front 69

Reversing Buckets

Back 69

The reversing buckets are also controlled by the Vector Control System and powered by hydraulics. The impellers turn the same way regardless of the boats forward or backwards movement. The buckets are what deflect the forced water in the opposite direction, causing the boat be thrust backwards.

Front 70

Backflush

Back 70

reverses the actual direction of the shaft/impeller (used for clearing lodged debris out of the inlet ducts) Do not exceed 1200RPM’s when backflushing

2 total- one on each engine
Belt Driven from the engine
Creates 120/240VAC
8.5k
W60Hz

Front 73

Generators--How they work

Back 73

• The generators create the 120/240VAC then send it to the ECU/ICS in the AMC space. The ECU/ICS converts the 120/240VAC into 24VDC which is then sent to the battery chargers. Though it may sound strange, the ECU/ICS then inverts 24VDC back into 120VAC which is then sent to the VAC panel under the chart table.
