It makes perfect sense. More weight = more drag = more prop slip. Prop slip IS the variable in boat performance. It accounts for weight, drag, aerodynamics, etc. complied into one variable. That’s why if you’re testing props, to compare performance accurately it needs to be done on the same day, same body of water, same weight etc.Propeller Slip Calculator Revised 20-APR-2013. Propeller Slip Calculator (PDF Preview) Propeller Slip Calculator (Excel Spreadsheet) (Index) Theoretical Speed Table. We have devloped a Theoretical Speed Table which calculates theoretical speed for various RPM, propeller pitch, reduction and overdrive ratios.From memory having the tip speed running at 1-3 times the the air flow speed is not efficient, but at least the propeller works over a wide range of air speeds. Highly tuned propeller tips are moving at 6x the air speed. However, their effectiveness at moving air disappears rapidly if the air flow is too slow. (The propeller blades are stalled)New Prop Availability. Availability of new propellers is difficult right now. Many models are on extended back order. Call or email for status prior to ordering.

BBLADES 4-SPEED.Slip is the most misunderstood of all propeller terms, probably because it sounds like something undesirable. Slip is not a measure of propeller efficiency. Rather, slip is the difference between actual and theoretical travel resulting from a necessary propeller blade angle of attack. If the blade had no angle of attack, there would be no slip ...BAM's online boating mega-catalog. All the parts and accessories you need to get on the water FAST!

Currently have a 17p prop on. at 2500 rpms on a 1.3 ration (mc-1?) we were doing about 18-19 mph - I entered that into some online calculators and it told me slip was 36%?!! That seems incredible - only a cruiser / fish boat - nothing manic. There is a 18" prop under the seat - or shd i go for 19?Slip is the difference between actual and theoretical travel through the water. For example, if a 10-inch pitch prop actually advances 8-1/2 inches per revolution through water, it is said to have 15-percent slip (8-1/2 inches is 85% of 10-inches). Similar to the airplane wing, some angle of attack is needed for a propeller blade to create thrust.The calculated value is indicated by the shaded heading in the table. This useful calculator computes the speed-of-advance of a propeller based on: propeller PITCH, in inches. The potential boat speed is then calculated from the speed-of-advance using SLIP, a percentage of lost speed, and unit conversion to boat speed in statute-miles-per-hour.BBLADES propellers prices are subject to change.

Using a prop slip calculator with the Viper prop at 5800 rpms and 47mph it shows 6% slip. When I plug in the Cyclones numbers it shows -2% slip. Using 6% slip in the calculations it says the cyclone would be 18.5" pitch.Rake is the angle of a propeller blade face relative to its hub. If the blade face is perpendicular to the hub, the prop has zero-degree rake. As a blade face slants back toward the rear of the prop, blade rake increases.

By using known values for the weight, power and speed you can come up with a more accurate constant for your boat. You can then see what effect changes to weight or power will have on top speed. Using the calculator in this fashion will produce surprisingly accurate results.kmclemore Site Admin Posts: 5934 Joined: Sun Feb 08, 2004 6:24 pm Sailboat: MacGregor 26X Location: Ambler, PA -- MACX2018A898 w/ Tohatsu 50D -- 78 BW Harpoon 4.6 -- 2018 Tahoe 550TF w/ 150 MercWhat would yall consider to be expected prop slip for a lightly loaded, riveted 1648 flat bottom with a 9.9 or 15 hp motor? I'm asking because I have this boat paired with a 1982 9.9hp Evinrude and am seeing prop slip anywhere from 20-25%. This is based off inputs of 5400 max rpms, 2.42 gear ratio, 10" pitch prop, and top speeds of 16-17 mph.Address BBLADES Professional Propellers N5007 Highway 73 Princeton WI 54968-8666; Phone Phone: 920-295-4435 Fax: 920-295-4436 Store Hours Monday - Thursday 8am to 4pm Friday 8am to 1pmPropeller slip calculator for powerboats Plearse use this calculator to figure out all parameters in regard to pitch, gear ratio, RPM, speed and slip.

Maybe the prop slip thing is a carryover from the nautical stuff. https://www.mercuryracing.com/prop-slip-calculator/ Page 148 in the ...the vessel’s speed. The propeller is operating in a wake. In practical terms, the wake fraction comes about this way: Suppose the open water thrust of a propeller is known at a given U and np. Behind a vessel moving at speed U , and with the propeller spinning at the same np, the prop creates some extra thrust.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. .
