Step 4: Select the Model of your engine. Alternatively, if you have the existing part # that is stamped on your prop, you can find all matching props here. Learn how to figure your power needs for any powered radio controlled boat. Important remarks: The propeller's pitch has a significant effect on the required engine power! Welcome to Graves RC Hobbies – your online hobby store and one-stop shop for remote controlled airplanes, helicopters, boats, cars and much more. There is some testing required here. Boat performance is equal parts power and propeller. Step 2: Select the Manufacturer of your Engine. The calculations and results are based on imperical data and formulas. Surfbaud Freeware Propeller Calculator is an Excel spreadsheet program. Mercury Propeller Selector. Is it important to know your prop’s slip? The calculated propeller sizes are based on standard propeller designs; 2 blade = 30% blade area ratio 3 blade = 50% blade area ratio 4 blade = 69% blade area ratio Usually the ratio ends up in the 2:1 to 6:1. The gear ratio needed depend on the properties of the motor and the type of propeller, pitch and diameter. 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. ... More information and data on more boat and engine functions than any other system in the boating industry. or. Prop Calculators on the Web. To produce the same thrust, a 6x4 prop needs about 156 W at 18630 RPM. Mirage Plus, High Five, Trophy Sport, Vengeance, Laser II, Black Max, Bravo Two. Mercury's Prop Selector Mercury's: prop selector is based off a complex formula to calculate the appropriate prop based on an approximation of your hull's performance characteristics. For instance, a 12x8 APC E prop takes about 86 W to produce 27 oz of thrust at 5000 RPM. Step 1: Select the Type of Engine (Outboard, Sterndrive, or Ski/Wake). Sport Series. Slip is the most misunderstood of all propeller terms, probably because it sounds like something undesirable.

Step 3: Enter the Horsepower of your engine. Get started now, and once you’ve entered your specifications, we’ll … 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. As the propeller (with high-pitch) rotates faster and faster it is stalling more and more. The results are only as acurate as the data you enter. Finding the correct propeller is as easy as 4 steps.. This is a fast boat you're building, and I have to admit I have limited experience optimizing RC speedboat propellers. Enter any 4 variables and the 5th variable will be calculated. Here at Graves RC Hobbies, we carry more than 27,000 different stock items, including almost any and every part of hobby toys you can imagine. It does generate higher inducted turbulent-resistance which takes engine power, preventing to produce enough thrust … A smaller prop requires more power to produce the same thrust as a larger one. Find your ideal Mercury Prop in 5 steps or less. Slip is not a measure of propeller efficiency. Only if you care about insignificant, little items like thrust. These props feature interchangeable Hub Kits allowing them to fit a wide variety of different motors at an affordable price point. Typically, when choosing a propeller you need to get a handful and compare which gives the most desirable result, whether it be highest speed or … Therefore any results in the calculated engine power field should be monitored carefully! With our propeller finder, you’ll be able to narrow your search for the most ideal prop considerably in just four simple steps.
