Sizing Propellers Those wanting to actually size a propeller for a boat (determine the best diameter and pitch) may find a free downloadable Propeller Calculator program from Castle Marine in the U.K. helpful. We (Polson Enterprises) do not provide assistance in sizing. Prop Calculators on the web. Mercury's Prop Selector Mercury's: prop selector is based off a complex formula to calculate the appropriate prop based on an aproximation of your hull's performance charecteristics.

Find your ideal Mercury Prop in 5 steps or less. Sport Series. Mirage Plus, High Five, Trophy Sport, Vengeance, Laser II, Black Max, Bravo Two Mercury Marine is a. They are engine RPM, prop gear ratio (normally for 1.5 to 3.0), prop pitch (the distance that a propeller would move forward in one revolution), prop slip (the efficiency of the prop, lower at high speed, but perhaps very inefficient at low speed) and the boat speed in mph. Enter any 4 variables and the 5th variable will be calculated Recommended pitch is theroetical as it assumes no slip. For very high pitch props (70-80) the calculated Tip Speed has been adjusted 5%-6% to approximate true helix Tip Speed. Otherwise circular Tip Speed is shown. Ideal Tip Speed varies depending on the H.P. per square ft of the prop disc Vicprop, marine propeller specialists. Propeller Selection . We currently have two prop size calculators (below), along with a collection of conversion style calculators to aid in determining various weights and measures relating to propeller selection

Press the calculate button to display the results. Using the back button on your browser Prop Slip Calculator. Is it important to know your prop's slip? Only if you care about insignificant, little items like thrust. Slip is the most misunderstood of all propeller terms, probably because it sounds like something undesirable. Slip is not a measure of propeller efficiency

Conversely, a two-inch decrease in pitch will result in an increase of 300 to 400 rpm. Going back to the question of performance at WOT, if your engine is under revving, consider a propeller with less pitch. If your engine is over revving, consider a propeller with more pitch. Elevation and Weigh Aircraft Propeller Angle Introduction. Gary Webster (EAA 837 Vice President) and I were having coffee and the conversation eventually came around to the difficulty of deciding on a the proper prop for a LSA or Experimental aircraft Your propeller is a vital link between your boat and the water. Optimize your boat's performance with a propeller from Michigan Wheel, Stiletto, Solas, Quicksilver, or Comprop. When replacing the prop, consider replacing thrust washers, aft washers, and prop nuts. Our selection of prop wrenches and prop tools make changing your propeller easier

  1. You will then be able to filter based on diameter, pitch, material, # of blades, etc. Match my current propeller to what is available (OEM) If you have the current model number of your existing propeller, the prop guide will display all available propeller matches that we carry
  2. The angle of attack is measured from the pitch gauge reference. In most cases this is different from the conventional airfoil datum. The default initial station position and station increment are taken from a Prather pitch gauge. If you have a different way of measuring a prop, adjust those parameters accordingly
  3. Pitch Speed is the Mean Geometric Pitch times RPM, which means the speed the aircraft would make if there was no slip. The Virtual Pitch Speed is usually 20 to 30% higher than the Pitch Speed. Often the pitch angle is not constant along the prop's blade, so it is typically specified at 75% from the center of the blade
  4. Distance from Prop Shaft to Pitch Station (In Decimal Inches, i.e. 3.5) Example of Angle Measurement 28 deg : Prop Blade Angle at Pitch Station (In Decimal Degrees, i.e. 33.5) This calculator is provided by IndoorDuration.co

Note: the 60mph is also the pitch speed of the propeller, which is an underestimate of the actual max thrust-producing airspeed, since I have not yet corrected the dynamic-thrust portion of the equation for the effects of things such as camber of the propeller and the unloading of the prop with increasing airspeed The propellers suggested by our Prop Calculator are based on Honda's extensive experience in prop selection. However, because boats vary widely due to a number of factors, it is not possible to guarantee which specific prop will perform best in any specific boating application get the best drive for your RC airplane! fast & reliable simulation - no more guessing most comprehensive motor database ☆ over 1 million calculations per mont

More accurate information for a particular boat/application may often be obtained from the boat manufacturer. The most effective method to select the proper propeller for a particular boat and engine application (based on usage and needs) is to test various propellers directly on that boat Selecting the Right Prop. The size of a propeller is defined with two sets of numbers, diameter and pitch, with pitch always following the diameter. Diameter. The diameter is two times the distance from the center of the hub to the tip of the blade. It can also be looked at as the distance across the circle that the propeller would make when. The pitch of a prop tells us the maximum distance a propeller will move a vessel forward through the water. Take note of the word maximum in this description. Pitch is often referred to as a theoretical measurement because no prop operates at one hundred percent efficiency
