Rust on Prop

[VABasser]

When the water was low I hit something awhile back that dinged my stainless steel prop. I think it was a concrete block, luckily I was going at an idle speed and besides some mild scrapes in the prop, there was no other damage. However as time has passed rust has developed in the three places the prop was dinged. It's still surface level but is this a concern? Is there something I need to do to protect it and prevent more rust? Thanks guys, here are some pics below

You should contact a good prop shop and have that propellor repaired. Since you are in VA consider Sanderson Marine 804-706-4100. They are located in Chester VA.

Use a wet stone and smooth off the edge, get rid of all the little burrs sticking up and smooth it off some.  That will also take care of most of the rust you are seeing.  Do Not use a file, or a prop shop will hate you.  Many times when you use a file, fine pieces of the teeth get buried into the stainless on the prop, so when the have to TIG the edges, that file metal can cause all kinds of problems for them.

I use a 41/2" side grinder with one of the heavy sanding disk and keep my leading edge almost knife sharp.  I will say, yours looks a lot better than my everyday prop.  It has all kinds of ugly places on the edge from sucking up stuff power loading on shallow ramps and one hit on a concrete ramp.  If I want max speed, I change props to one of my go fast props, but they are not used to power load or run in shallow water, and have no nicks or dings.  I've seen Just a couple small nicks slow mine five mph. 

Now, would I recommend you go to work on your prop with a side grinder, NO!  When I was racing back in the late 60's/70's I used to tune my own props so I have a little more experience.  Get one out of balance by much and it can play havoc on your LU.

Good advice thanks guys. Would using some steel wool be ok? I don't have a whet stone

Steel wool will not knock the burrs off, an they tear the steel wool to shreds in no time.  Heavy backed 120- 220 sandpaper on a stick will work also
