Cavitation

Does true cavitation ever occur with an outboard? Under what circumstances might it occur?

Love the avatar!!! How fast does it go. You probably could go with a 14 x 100 prop. That would be one heck of a ride. To bad you wouldn't live to tell

Re: Cavitation

I am. There's a Boaters World on Kingston Pike. As for lumber, I've never looked for any marine. In the yellow pages I found Jeffries Wood Works (advertise fine hardwoods), 573-5876. If you're looking for marine plywood, about any lumber co. can get it, but expect to pay dearly wherever you get it.

Re: Cavitation

Cavitation is when water separates from the prop blade and causes vapor, which boils in the transformation and can erode areas on the face of the blades. In most cases, cavitation is induced by a nick or bend in a blade, or in some cases, even the wrong application.

Re: Cavitation

And yes, it can occur with any prop, whatever motor drives the prop.<br /><br />Slower the prop, the less likelihood of cavitation. It varies with water depth too - that's just one of the reasons why subs have big, slow-turning props.
