Any prop shop can order you what you need:

Bay Propeller- PROPELLER SHOP - Welcome to Bay Ship & Yacht Co.
The Prop Shop- San Francisco Bay Boating: The Prop Shop

Or if you want to look for something used:

Blue Pelican Marine Consignment- Blue Pelican Marine Nautical Consignments - Home

If the prop is pink.....there must be no zinc!

Sounds like a good case of electrolysis. Unless I'm missing the punchline. ???

No input on the prop but congratulations on the new baby!

Thanks,

I think the story is the bilge back up, pump failed, frayed wires sat in the water and corrosion ate up the water cooling exhaust valve and through haul, zincs and prop. 9mths layoff. I' m surprised she didn't go down. She now on the hardball waiting on a new prop and is back in tip top shape for an 72 cal 34.

Pink mean dezincification, not electrolytic corrosion (often mistakenly called electrolysis, which is a different process.) Dezincification occurs when the the zinc component of bronze is depleted due lack of protection by a zinc anode, rendering the bronze part much more like brass, which quite brittle.

Like the old AAMCO commercial, "You can pay me now, or you can pay me later."

Good to know. If its pink electrolysis was not the cause.

Is my shaft zinc only protecting my prop? I've gone thru 3 this season and have been trying to isolate the cause. Could be external but most likely not.
Thanks.

It is protecting whatever underwater metal parts that it is in direct electrical contact with. Typically your shaft and prop.

Fast Bottoms can you put me on your automatic sch. for zinc replacement. Kyle@pasair.com
