How to measure the PITCH and tell which hand it is.

I'm a parts guy at a primarily outboard service shop. A couple of our used props were missing the markings. You just saved me so much hassle trying to guess at what these props are. Much appreciated!

Now that was simple! The other guy on KZfaq who says his method is simple just complicates things! Thanks!!!!

Very useful. The last video I saw about propellers was on aircraft but mentioned is was hard to measure the pitch. You made it easy to understand and apply. Thank you!

Thanks for this informative video. On my Yamaha 60 hp it is a composit propeller without any data. With your video I found out that it is a 13x16,59 pitch propeller. 😊👍

Hello,great vidéo, if I understand ,I can reduce the pitch by reducing the angle .

@annemarie1959 2 жыл бұрын

The pitch and radius create thrust which must be balanced to the engine power which affects the max revs available.

You should do this measurement at different diameters to see if the twist is correct.

does this math work with any type of prop

@savingannemarie5938 Жыл бұрын

It should do. It measures the distance travelled through one rotation of a single blade so would do the same for a two, three, four or more bladed propeller. It’s only measuring pitch and diameter. Thrust and power will probably be based on the engine output power, speed of rotation and displacement of the craft. Thanks for the question.

Hardy McKinney hi Hardy. Once you know how to measure a prop it makes you want to do it some more. It’s such a simple technique but weirdly interesting. Thanks for your comments.

@ChrisKirtley Жыл бұрын

Why wouldn't you just have one propeller design that maximises pitch? For example, why are some 2 blades, others 3 or 4? And surely it would be best to angle the blades as much as possible?

@savingannemarie5938 Жыл бұрын

It depends on what you are trying to do. A powerboat that wants to cruise at 30 kn has a different need to a sailing yacht. One will have a high powered engine revving very fast and providing loads of thrust. The other turns over at low revs with a maximum speed of 6 kn and an engine of only 50 hp. It’s definitely not one size fits all.
