240 KW and powered by C9 tier3 Caterpillar engines. They are 60 cycle.
Units were manufactured in 2013, and were installed in the boat in 2015.
They have close to 10,000 hours on them, which is why they were taken out of a 230′ yacht.
Engines were running good when they came out. There was an overhaul required to keep them in class, and the work required the engines and alternator ends to come out of the boat anyway, so the owner decided to just put new ones in.
