Sunchaser,
This question of continious rating has been in my mind a long time .. for no paticular reason though.

For the 5.9 does that mean continious at WOT or just at that rpm?

IMO any of the diesel engines we have here on the forum should last forever given no overloading and good maintenance. But continious rating (propperly loaded) is another issue. But most diesels should be fine 5 or 10 minutes at WOT. And many are probably good for 1/2 hr or so. But most boats are so overpowered that even WOT for any period of time would be pointless except fot periodic engine check. I do WOT 2 or three times a year or to check a prop.
