Princess Charlene and Prince Albert, who are parents to one-year-old twins, Prince Jacques and Princess Gabriella, have been captured in a fly-on-the-wall style video released by the palace to celebrate the festive season.
When selecting a propeller pitch for your boat, it is important that the propeller runs at the upper end of your engines wide-open-throttle RPM range. If you want your RPM's to increase, go down in pitch. To decrease RPM's, go up in pitch.As a general guide, for every 2 of pitch, RPM's will change approximately 400 RPM's. For water sports or extra people on board, you should generally drop 2 of pitch to help compensate for the added weight and drag on your boat.emember this rule of thumb: For every 2 of propeller pitch, rpm's will change approximately 400 rpm's. As you drop in pitch, rpm's increase, and as you go up in pitch, rpm's decrease. So if we want to raise our rpm's we should choose a lower pitch prop.
If you don't know, diameter and pitch usually are stamped somewhere on the prop. Also know the engine's rpm at wide-open throttle when your boat is running with a typical load and trimmed for best speed. Perhaps what's most important is your performance goals.
