thoughts on annual cost to run 4 ips 600 pods on an 04 68 Azimut?

I have no experience with the N14's. But I never liked 3208's, the lack of liners and they always seem to have greyish/blue smoke at slow speeds, and the undersized cooling systems on them......I also don't like how they act like GAS motors when docking and you usually have to apply throttle in addition to gears on most boats that had them...…..in that HP range and era I always liked the Cummins 6 B/BT/BTA's or 6-71's (although these are always noisier).

It's very easy to spot. The aftercooler cover on the center, top, exterior of the engine, looks totally different between old and new style.
