The formula below is for sizing props from "no slip" to "average/expected" slip, so the answer is in the format of 1 + slip. Subtract 1 from answer to get the "average/expected" slip for the speed (be sure to use knots and not mph).‎Propeller slip calculator for powerboats Plearse use this calculator to figure out all parameters in regard to pitch, gear ratio, RPM, speed and slip.

So I was using mercs prop slip calculator because I was interested in seeing where our boat is at with the Maximus 32's. I put in at the info in and came up with between 1 to 2% slip. 32p props, 1.36 gear ratio. Is that even possible? sorry for the pic quality, these are screen shots of a video:Add More Weight to the Boat. One way to reduce prop slip is to add more weight to the boat. This will increase the downward force on the bow and help keep it pushed down into the water. You can add weight by filling up empty containers with water or sand and placing them in strategic locations on the boat.Divide by 5280 = Miles per minute, multiply x 60 = miles per hour. This can be shortened to (Pitch x RPM) / (Reduction x 1056) = MPH. Slip is figured by comparing this theoretical speed to the actual measured speed. By the way, for these calculations, add 1" to the pitch if your prop is cupped. (Just about all hi-performance props are)You can use this boat propeller calculator to determine one of five variables: boat speed, propeller slip, propeller pitch, engine gear ratio, or engine revs. To use the calculator, input four of the five variables. The calculator will automatically compute the 5 th variable. Boat Prop Calculator Boat Speed Engine Revs Gear Ratio Propeller Pitch Apr 28, 2020 · 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. Besides delivering an incredible hole shot and awesome acceleration, the Lightning E.T. also produces natural bow lift, reducing drag and increasing the efficiency of the boat. This adds up to higher speeds and better fuel economy, requiring less engine trim. 14.5″ diameter. 26″- 32″ pitch in even increments.

Large “go fast” boats with special stern drives can use propeller diameters ranging from 15 inches to 18+ inches. House boats and slow moving non-planning hulls may use diameters well into the 20 and 30 inch areas. Number Of Blades. The number of blades on a propeller also affects the consumer’s decision when shopping for a new propeller. I have a x19 with a flashed 200 SHO.
