Maximum efficiency means finding the best relationship between the propeller on the one hand and the boat, engine and buckle on the other.
The engine should reach maximum revs at full throttle. Diesel engines are designed to operate at optimum speeds. To achieve such revolutions, the propeller must allow the engine to achieve the maximum rated revolutions at full throttle. In most cases, the engine does not achieve this, mainly due to an inadequate propeller. This causes a reduction in speed and overloading or underloading the engine.
Overloading causes incomplete combustion which is reflected, along with other problems by the appearance of thick black smoke. This ultimately results in higher fuel consumption and engine damage.
Other factors that affect the reduction of engine speed are: increase in the weight of the ship (displacement), increased temperature of the engine cooling water, dirty air and fuel filters and finally dirty (overgrown) hull.
Vibration and cavitation can also cause performance degradation. By optimizing propellers, Adriatic Propeleri can help you eliminate such problems and improve the performance of your boat. The table on the right shows a visual example of the vibration strength of propellers of different classes.
