They are still making the Series 60, however it will no longer be available from 2010 on as it does not meet the new emissions standards and MTU doesn't want to spend the money and research to get it there. The series 60's are good motors for both torque and longevity.
DD/MTU actually pulled some of the test engines apart at 500k miles. I spoke to the mechanic that dyno'ed it and pulled it apart, the engine made more power with 500k miles on it then when it was new, had no wear inside, and when they installed new rebuild parts (rings, bearings, wear parts etc.) it made less HP on the dyno. He has seen some go well over 1million miles.
2. CAT still produces C18's (1015hp version) and they are installed in many new boats. CAT's first priority is supplying manufacturer's with them and contracts, then selling engine's to the average Joe comes second.
Thanks Capt J and K1W1. That's the info I was looking for. Trying to sift out the most current and correct info off of Google can be a challenge at best.
