3-bladed or 4-blade propeller for your Honda outboard motor

Most Honda outboard motors are standard of a 3-bladed propeller. In most cases, that also the best result in the combination of slip in acceleration at low engine speeds and good grip at top speed.

As much grip at low engine speeds is desired, for example, to wakeboarding or water skiing, a 4-blade propeller benefits. This will boot faster respond to gas with the throttle. That is especially important at the start, but also the speed is


What is the diameter of a Honda boat screw?

The propeller diameter is the distance between the imaginary circle that wraps around all the propeller blades.

What is the Pitch of a Honda outboard motor screw?

Pitch is the theoretical distance a Honda propeller travels with each rotation. For example; a 21 boat screw pitch would be a boat at each rotation 21 inch (2.54 x = 53.34 cm) have to move on, assumed that there is no slip

What is the difference between a left-turning or dextrorotatory Honda screw?

In most cases, ben in boats with a single outboard engine a right-handed screw used. Left-turning propellers are used in the Assembly of double motors for better handling characteristics.

How do I choose my boot screw?

By default, a Honda outboard motor comes with a so-called standard screw. This one is so chosen that he meets in combination with most boats behind which the Honda outboard motor <./p>

The most important factor for the match between the Honda outboard motor and the boat is the pitch of the propeller. That determines the ratio between the engine speed and the speed of the boat. The pitch is the distance a propeller moves when he finds himself one rotation by the water "unscrew". A boat screw with flat blades made a short distance. If the sheets are placed schuiner is that distance is greater. In a comparison with the data of a car can say that the boat at a small prosperity in a lower gear than if the propeller is a matter of urgency. That affects the speed of the boat at an engine speed, but also on

the pull.

To choose the right propeller must first be measured whatever speed the engine is running at top speed. Then the speed recommended by the manufacturer in the work area. Usually that's anywhere between 5000 and 6000 RPM. It is recommended also to measure the top speed with a GPS.

You go for a maximum speed, then the engine speed in the direction of the maximum value within this area. The measured speed is lower than the indicated operating range then there must be a propeller with a smaller emergency. After mounting the new prop will be the top speed achieved more quickly: the pull is at the same time larger. In addition, the top speed despite the smaller prosperity often slightly higher, because the engine in its optimum working speed. Of course, after changing the propeller always check if the engine at top speed in the specified rows. Conversely, a propeller with greater prosperity the solution when the engine at top speed makes too many revs.

The table below gives roughly to the impact on the speed as the pitch of the propeller. This is related to HP-class of the motor.

That also means that the choice of the emergency depends on the intended use of the boat. If the boat is only used to quietly revving it might be more comfortable to a propeller with a slightly larger prosperity to choose (1 size larger). The engine speed remains lower, the boat is more economical and the engine is quieter.

Conversely, it can be useful for water skiing to choose a smaller emergency: the motor running then more touring and has more pull. The top speed is limited because the engine at it's maximum speed is bounded.
