    Pitting on s/s prop-gctid405445

    I am looking at buying a second hand 21" high five prop.

    It is too far away to inspect so I can only inspect via photos.

    I noticed it has some minor pitting on the sides of the few blades and a small amount on the face of one blade.

    These props are really expensive in Australia, so I thought I might opt for a second hand one.

    Would this pitting cause an issue or not?

    Can anyone offer some advice on the pitting issue?

      Pitting can be a cavitation issue, or an electrolysis issue.

        This is a prop I am looking at buying.

        It is not on my boat.

        Will the pitting cause any issue with performance?

          Obviously it depends on the severity. If minor it can be polished out. If major it wouldn't be good.

              Either way, take it to a prop repair guy. They can fill the 'voids' with weld and buff it up and tuned to like new. Might as well have the hub changed while your at it.

                Cavitation would be on all the blade tips, a prop repair shop should look at it and give you an estimate of repair before buying.

                  I'm going to go the other way: Based upon your picture, I would not hesitate for a second to run this prop without any further concern. The blade surfaces look just fine, and will do exactly what they are designed to do...take you boating!

                  Happy boating!

                    I agree - especially if you are getting it for a great price.

                    If it is higher priced, then have the owner do the work on it.

                    Either way it would be fine to run.
