Measuring a propeller's pitch

[@ashishsrivastava6024]

this is the best technical video on you tube which explained so nicely and precisely

[@Caldor101]

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!

[@savingannemarie5938]

I’m glad you found it helpful.

[@methods-SE]

Thank you
Its funny... 420 pages of Minn Kota search results and not one tells you the pitch of the stock prop. Just PN's and Jargon. Thank you for explaining this so clearly. I will try it for my prop.

[@Richard-kz2om]

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

[@savingannemarie5938]

Thanks for the comment. I am glad it was helpful.

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!

[@annemarie1959]

Thanks for the message. I’m glad it was helpful.

[@arsiize]

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. 😊👍

[@annemarie1959]

Thanks for your comment. I am pleased that the video has helped you.

[@fourfortyroadrunner6701]

HOLY COW this is well explained. I didn't think something this useful WAS POSSIBLE on TH-cam!!!!

[@nathanmayo7101]

I get it. What a wonderfully simple and easy to understand description

[@simonhale3641]

Superb explanation - thanks very much!

[@garygeorge4105]

Thanks so much.I was able to work out prop.size and pitch for a model launch I have,so as to order new prop.with more pitch.Gary

@@_Spread_Positivity_ hi I have looked this up and it is complicated. There are some videos on TH-cam that might help.

[@HexterTheJexter]

Excellent explanation THANK YOU!

[@senousyoucef989]

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

[@annemarie1959]

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

[@ken2633]

Would the calculation be same for a 2-blade prop?

[@nitinpai9452]

This is next level explanation ...

[@farmer87yj]

does this math work with any type of prop

[@savingannemarie5938]

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.

[@ChrisKirtley]

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]

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.

[@mamatuja]

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

Hi Hardy. I bought a new one thanks.

I'm going to see what's the pitch on mine is thanks for the video.

[@hardymckinney3298]

it's an 18 inch like the one in your video

[@savingannemarie5938]

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.

[@arvidmartinkat48]

Nice

[@jamesfackenthal]

Your turning it backwards. It's a clockwise rotation propeller. Not counter clockwise.

[@imperialrecker7111]

It depends on what you use the props for

[@craigbielsky115]

YOU WERE TURNING IT THE WRONG WAY LOL...

[@Saruzzu2]

LoL, he was turning looking from the "back", hence3 in the correct way.
