USING THIS GUIDE PROPULSION ENGINES For propulsion engines, the application ratings reflect various boat operation needs. Knowledge of the engine’s operating requirements is therefore essential to establish a proper match of engine rating to boat operating requirements. Consider the expected annual operating hours based on the annual 12-month period. Also consider the duty cycle, which refer to the amount of time the engine is required to be operated at rated rpm during a period of time. Then review the presented application ratings and decide which rating best defines the application. Also foresee...

DIMENSIONS & WEIGHT Dimensions and weight may vary according to the configuration selected. More detailed information is included within the specific installation schematic for each product. Stated weight values are based on dry engines including standard equipment without coolant, oil and transmission. Sizing is defined according to the following schematic diagram: Length clutch For propulsion engines, performance data are provided in accordance with ISO 8665-1, as follows: kW: Rated engine power in kilowatts hp: Rated engine power in metric horsepower rpm: Rated engine speed in revolutions...

Nanni works with various marine classification societies to allow the use of our engines in vessels designed and built to a society’s particular requirements. For more information, please contact your local Nanni representative. The SOLAS (Safety Of Life At Sea) is an international treaty that prescribes several rules regarding the safety of ships. Our SOLAS approved engines are designed and manufactured to meet these regulations for use in life, rescue and crew tender boats. Special features do include: ■ Immediate starting in very low temperatures (down to -15°C, and -25°C with additional heater)....
