Stainless Steel Duo Props

taza

Both props have holes on the inside, will this effect the performance, looks like a casting issue

These are 2007 Volvo Props

any help appreciated

Giving the location, I do think so.

Just out of curiosity, what do your anodes look like and is your bottom paint touching your outdrive transom plate?  

With shot anodes, paint touching the outdrive and salt water corrosion happens quicker than an old toyota rusting on new englands salted winter roads.

Anodes changed every year,no paint touching the outdrive,for the last 2 years 5he boat has been on a swinging mooring for approx 5 months per year with no hook up, before that the boat was on a pontoon 6 months a year with electric hook up at weekends

They look kind of dangerous....

With thru hole corrosion like that, you can bet other places are thin too. Those are seriously compromised: replace. Unusual to see the SS take the hit like that though.

I can't imagine that...I'm not super experienced but I've never seen aluminum props like that...

I think if aluminum props ever got to this point, they would get wadded up pretty quickly. There wouldn't be a discussion of whether or not to replace, it would be mandatory haha.

Thread title says, "Stainless Steel Duo Props", but I have to agree with others, looks like aluminum. Were Duo props available in aluminum? I thought they were all SS. I'd get rid of those, pronto!
