It was great to catch up and put more faces to names, and to share anecdotes. And yes, I am delighted with my systems refit.

At the John Deere stand I was surprised to be told that the new tier 3 4045's are smoother than the 6 cylinder engines, thanks to wonders of CAD, and two balance shafts. They are also rated up to 225 HP.

But I still would have chosen Tier2 6068's - no aftercooler or high pressure common rail complexity.

The other interesting comment was that the tier 3 engines are not as fuel efficient as the tier 2 engines. So, lower emissions come with a cost in fuel consumption. Although I suspect only high useage such as commercial boats or farmers would do enough hours for it to become significant.
