Maximizing Efficiency...

Maximum Efficiency means finding the best possible match between the propeller and the boat, engine, transmission combination. There are a few things you can do to make sure your vessel is maximizing efficiency:

Make sure the boat is able to achieve the wide-open-throttle RPM at your desired vessel weight. Diesel engines are designed to operate at an optimal speed. In order to achieve that speed, the propellers must allow the engines to operate at their wide-open-throttle. In some cases the engines do not turn up to the rated RPM because the propellers may be the wrong size. This causes the engines to run slower and become overloaded. Overloading causes incomplete combustion that, in turn, causes excessive carbon build up (among other problems) leading to premature wear and ultimate failure. Other factors that decrease RPM and overload the engine are increasing the vessel weight, higher water temperatures going through the vessel’s heat exchangers, increased ambient air temperatures, dirty air and fuel filters, and a dirty hull.

Vibration and Cavitation are two common propeller-related problems that can be major reasons for not obtaining performance. Adriatic Propeleri can help by either altering your existing propeller or by providing the correct design to reduce or eliminate propeller induced vibration or cavitation.

 

Vibration and Cavitation can also reduce boat performances. Optimizing and tuning the propeller, Adriatic Propeleri can help you to eliminate such problems, increasing the overall performances of your boat.   The table right, shows a visual example of the vibration amounts of different class propellers	Prop Scan Class 0
