(single prop drives on planing boats is usually 12-15%) This indicates that your tach might be off by more than 200 RPM. Since you KNOW the ratio, prop pitch and speed, you can use the calc to figure your theoretical speed (zero slip)When calculating slip only consider pitch, not cupping, diameter, or # blades. You do not add pitch for cup when determing slip. Cupping loads the prop more and can reduce slip, but so does adding diameter. % slip depends on vessel type and slip will vary differently throughout the rpm range.Prop Slip Calculator; Used Propeller List; Contact BBLADES Today!

Propeller slip is a term used to describe the difference between the theoretical forward speed of a boat and its actual forward speed. Propeller slip is a result of several factors, including the design of the propeller, the efficiency of the drive system, and the water conditions. Understanding the concept of propeller slip is ...The boat was fast enough on flat water, about 33 mph and almost never hit the rev limiter. About 5 years ago I decided to do something about the performance. I installed a Bob's Machine Shop Anti-Ventilation Plate and at the same time purchased a Propulse 4 blade propellor, which I set to an 18 Pitch.How To Calculate The Prop Slip? If you don’t want your prop slip to extend every now and then, do the right calculations. You can easily calculate the prop slip while lubing the steering cable on the boat. You can also calculate it any other time. A propeller for a boat has two fundamental dimensions. The first is diameter, and the second is ...Mercury Racing has released a new propeller-slip calculator app for Apple or Android smartphones. The app has all the functionality of the calculator at mercuryracing.com, which makes propeller testing easier and much more accurate. It can be downloaded for free from Google Play or Apple iTunes. Mercury Racing’s propeller guru, Scott Reichow ...When there is "more slip" it is easier for the propeller to move water out of the way, but when there is "more" slip we move a slightly shorter distance for each revolution of the prop. A smaller prop will usually display a bit lower calculated "slip" ratio, but may or may not be a sufficient advantage to generate the result of higher measured ...Re: prop slip calculators and boat speed calculators I agree, getting 40+mph out of a 150 on a toon is tough work. Hell, a 3000# mono hull boat won't reach much past 40mph with a 150 on the back.

Boat Prop Calculator Boat Speed Engine Revs Gear Ratio Propeller Pitch Nov 7, 2018 · So, a prop described as 15 x 18 x 4, is a prop with a 15" diameter, an 18" pitch, and has four blades. Pitch is not so easy to measure. Then, there is slip. Propeller Pitch. Pitch is NOT measured the same way as is diameter. It is NOT the distance from the leading edge of the blade where it meets the hub to any part of the trailing edge. Plug in your info, and click "Calculate" on the item you want to compute. 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.The Lab Finished MAX5 provides a measurable reduction in propeller slip, (up to a staggering 12% in some applications).

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.When they talk about "prop slip", they are not talking about the prop physically slipping on the hub. Prop slip is the loss of bite in the water. No prop is 100% efficient, so therefore it will "slip" in the water not grabbing all the water that it can theoretically push. My prop slip is calculated at around 7% which is extremely efficient.There are several prop slip calculators on the web, search for one and plug your numbers in. You should get around 10-15% slip. R.
