I think that's the bigger hpdi engines (200 or 250 hp and above). We push our engine pretty hard, cruising rpm at around 4.300-4.500. My problem with Yamaha is that spare parts are so expensive.
The previous owner of our boat got the hood for the engine stolen and didn't think about putting a bag over the engine when it was raining so our engine is pretty much ruined (but running) and it's really not worth it to change all the electronics in the engine, almost cheaper to just buy a new engine...
Sorry for being off topic...
