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.
You need a prop that allows your motor to reach that rpm range without going over it, when the boat is loaded as it will normally be used, and the throttle is wide open. As big as that boat is, you should probably run a 10 7/8 X11 prop (11 being the pitch, 10 7/8 the diameter.ou will likely only be able to run a 11 pitch prop on that motor. A prop is selected not for the size of the motor, but for how fast the motor turns when running wide open. Your motor has a maximum Wide Open Throttle (WOT) rpm range that is determined by Mercury.
