Choosing the right propeller is the single most important decision you
can make to get the best performance from your boat and outboard!
Propeller choice can affect boat top speed by as much as 5 to 10 MPH. A
It also has a direct effect on acceleration, cornering, pulling power, and
fuel economy. With some boats, you may need to change propellers for
different activities, such as high speed cruising, water skiing, or carrying
heavy loads. Using the wrong propeller in any of these applications will
not only hurt performance, but could also cause engine damage.

WHAT TO CONSIDER WHEN SHOPPING FOR A PROP
Several characteristics affect how a propeller will perform. Especially important are propeller diameter, pitch, rake, and cup. Most propellers are
identified by their diameter and pitch. Look for a number like 143/4 X 21. The first number is the diameter, the second is the pitch. In addition, it is
important to understand the effects of ventilation, cavitation, materials, and other application variables on propeller performance.

SELECT THE RIGHT PROPELLER FOR YOUR BOAT AND OUTBOARD
WARNING
For dual-outboard installations, always check to be sure propellers are installed on the correct engines before aggressively operating the boat.
STEP ONE
Choose the propeller type designed for the way the boat will be used:
• Fishing, skiing, cruising, commercial, racing, etc?
• How many people will be on board?
• Is the water shallow, or are there rocks or other underwater objects?
• Will the boat be used for multiple purposes?
Use the propeller family descriptions in the following pages as a guide. For example, a Rebel™ propeller could be a good choice for a large, offshore
boat. In contrast, a Raker® propeller provides bow lift, for increased top speed, on small, fast boats.
STEP TWO
Find the correct sized propeller for your specific outboard, boat, and load combination. When selecting a propeller, start with the propeller charts
in the following pages. These charts group all of the propellers designed for a particular outboard and provide detailed information such as pitch,
diameter, style, and the number of blades.
To complete the selection process, you must perform a water test. During this running test, you will determine the best combination of engine
mounting height, propeller style, and propeller pitch.
Operating Range
All Evinrude and Johnson outboards have a recommended full throttle operating range. This means

that, at full throttle, engine RPM must never be below or above this range. These specifications can
be found in the Operator’s Guide. H 100%

When you have a selection of propellers ready for testing: RPM
1. Use an accurate tachometer to measure RPM and an accurate speedometer to measure boat
speed.
2. Testing should be performed with the typical load—number of people, gear, water in live wells, etc.
3. Make sure that every test is with an identical setup.
4. Test each propeller at wide open throttle (WOT).
5. Engines should be tested at their optimum trim angle. This is the highest trim position the engine can be run without excessive ventilation, either
in a straight line or in turns.
6. If the RPM is too low at WOT, try a reduced pitch and retest.
7. If the RPM is too high at WOT, test a propeller with more pitch. One pitch size usually results in a change of 200-300 RPM.
8. If the boat will be used for two applications, like water skiing and cruising, it may be necessary to test propellers for each type of use.
STEP THREE
Adjust the engine mounting height for peak performance. The ideal engine mounting height provides the fastest boat speed without sacrificing
acceleration, maneuverability, or engine water pressure. It is achieved by a trial and error method.
1. Start with the outboard’s anti-ventilation plate even with the bottom of the boat.
2. Raise the outboard one mounting hole at a time until engine performance is no longer acceptable. Then, lower the outboard back down one
hole. Optimum engine height is affected by propeller style, diameter, and pitch. As you raise the engine, you may need to
experiment with a variety of propellers to maximize performance.
THINGS TO REMEMBER
Check full throttle RPM often. It is possible that the
propeller pitch size may have to change as the boating
application or load changes.
• Adding or removing people can significantly change the
power requirements placed on the engine.
• Changes in atmospheric pressure, temperature, and
humidity all affect engine performance, which directly
affects propeller performance.
• Salt water is more buoyant than fresh water; this may
cause some hulls to run faster when moving from a
fresh water to salt water location.
• The accumulation of marine growth or dirt—moss,
barnacles, lime deposits, etc—is a major cause of poor
boat performance.
