CAT C18, C32 and C32B are the current Caterpillar manufactured Tier 3 available engines.

Some of the older CAT non Tier 3 engines may be available for certain situations/installs.

Btw, my CAT mechanic is telling me C12.9 is now good to go, CAT apparently has addressed all the early issues.
Didn't get any info on the smaller engines.
I thought the Iveco marine diesels (FPT) had the best power curve when I was digging deep...but that was about a dozen years ago.

The thing is, the Iveco brand was selling for about 20% less than the Cats. So, that's a lot of $ for a different name badge stuck on there. Yeah, I know there are some differences and service, etc etc. But still.....it's even called "C13" in the Iveco lineup. The C13-770s are where I'd look first for my 52C if disaster strikes.
