" an engine will not run on exhaust fumes"

Might want to advise the EPA , all too many engines have EGR (exhaust gas recirculation) where the engine is forced to eat exhaust by the Air Police.

If any one is buying a boat in Florida with 3208 engines, you might want to hire an engine surveyor who has a phone number that explains his specialty -Bruce Hicks 954-661-3208

My RV 1160 CAT is rated 210hp at 2800rpm.

The 1160 was the industrial daddy to the 3208 , but with real diesel cylinders was too expensive for the 3208 market.

I too worry about 2400 being way to close to constant overload.

That's why I asked what you get on the pin, full throttle. ?????

RPM alone doesn't mean an engine is loaded or not, after all the highest rpm you can reach is high idle and that is obtained with no load.

Overload is defined by the power output at a given rpm, look at the propeller curve, not just the tach alone. After all, isn't that what you are doing when you promote the idea of a "cruise prop?"

That's why I asked for the rpm he pulls at flank underway.

IF he can get to rated 2800 rpm 2400 should be down enough due to the prop curve to not be an overload.

My problem is 3208's are neither strong or powerful and easy to overload.

The cruising prop concept is not for a plaining boat in a big hurry .

It it to rationalize the stoopid sized engines frequently stuck into displacement boats , that are attempting to get better fuel burn , lower noise and a non slobbering engine operation.

Take a look at a "Closed Cycle Diesel" and see how much fresh air it needs.
