Changing out my water pump and noticed it was ripped apart. Didn't know why till stumbled across this video. My propeller has all kinds of nicks and wear and tear all over it. Now I know why ! Thanks for the video !

Been boating for years good explanation

Great video and explanation mate!

Thank you for this. I’ve found myself confused trying to understand this concept. Makes perfect sense now!

very well explained by you and understood well on this end because your explanation of a complicated physics situation was applied and demonstrated on the prop with your fingers on the edges. I've heard this explained a 1000 times by very well informed and knowledgeable people, your explanation visual demonstration best by far. thank you.

You taught me something new, ole timer! Thanks for the video

Wow man thank you, super informative

Thanks for the great video! How will I know if my engine is mounted too high? What are the clear signs that the propeller is getting air, even a little bit?

Yep. It helped. Thanks!

Great explanation. Thank you!

Very well explained.

You have cavitation a little backwards. The vapor bubbles are formed at the leading edge of the blade and collapse at the trailing edge. Cavitation happens when there is a lack of net positive suction head NPSH. In the case of a propeller, NPSH is obtained by the speed of the water, towards the leading edge of the blades. This is why high pitched props, cause cavitation during hard acceleration. Once the boat is up to speed, the cavitation goes away.

Thank you. Best explanation I found.

Great explanation! Thanks!

really enjoyed the information thanks for sharing

Much Thanks 🙏🏼 from down under 🦘

Great job. I am a newbie and you explained this very well

Best video on KZread!

I like people like that smart and simple and knowable not too many people left like that

Good Stuff...Thanks
