The old adage of "buy more motor and use less of it" may apply to some boats, while other boats actually run better with less than the maximum rated horsepower
These models bring new features such as Pivot Pro, independent float, an industry-leading 260 rated horsepower

Normally, all that is given is the rated horsepower
of the fan motor.
I believe most aircraft engines are set up to produce their sea level rated horsepower
at a fuel flow resulting in EGT that is 150 to 200 degrees rich of peak.
Deutz has invested in two dynamometer rooms, with 150 and 250 kW Taylor dynamometers to run every remanufactured engine through a 20-minute quick power pull test during which high and low idle are set and the engine is run up to its rated horsepower
"Unfortunately, machine performance is typically the result of the rated horsepower
or engine output of the unit," he says.
Today, it's much more common to see motors with lower rated horsepower
and higher service factors.
The new series consists of the smaller indirect-injection 2TNV70 and 3TNV70/76 with rated horsepower

In its Performance Handbook, Caterpillar notes: "Specification sheets show how much pull a machine can produce for a given gear and speed when the engine is operating at rated horsepower
. When a standard machine is operated in high altitudes, the engine may require derating to maintain normal engine life.
