Buying Guide

Propeller is one thing where you don’t want to invest without research. This hefty thing might not work correctly if you get the wrong one. So, in this case, what do you do?

You look into the necessary stuff first and then go fishing for enhanced features. Now, this leaves people wondering what are the main features of the Mercury 4 stroke propeller.

Well, here’s the list-

OEM Number

What makes it easiest to buy a propeller for the 40 HP Mercury 4 stroke is if you know the OEM number. Hold on, what is an OEM number?

You see, OEM stands for Original Equipment Manufacturer. Basically, it is a number that tells you whether the propeller is genuine or not.

Moreover, based on the OEM number you can determine easily which propeller will work on your boat motor. So, that’s one way to go for the propeller. However, there are other factors to consider too.

Material

Yes, the material of the propeller matters too. Like any other equipment, even the propeller has to be made out of premium materials. Otherwise, it won’t be able to serve its purpose. 

In general, propellers are made of 2 things. Aluminum and stainless steel. Now, both of them have their own special features.

For instance, aluminum is comparatively cheaper but it’s less durable than stainless steel. However, the blades aren’t that stiff and you can repair the aluminum propeller quite easily.

Whereas on the other hand, while stainless steel might be a bit more pricey it sure is durable. So, stainless steel is a good investment in the long run. But you should be aware that they are harder to fix if damaged.

Size

When talking about propellers we mainly address two numbers. One is the diameter and the other one is the pitch.

Now, diameter is the distance from the center to the tip of the blade. Whereas, the pitch is the circumference of the path that the propeller spins in one round.

Propellers with smaller diameters are meant for smaller motors whereas the bigger ones are for the bigger motors.

Coming to 40 HP Mercury 4 Stroke you will need the right size. However, there are a few sizes of propellers that will suit the motor that you have. So, before buying make sure that the sizes are compatible.

No. Of Blades,

One more aspect that you should keep in mind is that propellers have different numbers of blades. The most common number is 3 or 4. Meaning that the propeller may have 3 or 4 blades.

So, is more blades better?

In general, the propellers with 4 blades are faster. However, propellers with 3 blades tend to be available more in the market. Plus 3 bladed propellers come in multiple sizes. So, you can get the right size without much of a hassle.
