[Public-List] Foul Prop

[Jay Davenport]

Chris,
I had the same problem last season. The prop had to be dived on to clean off the barnacles. 
This year I have had no barnacles. George Dinwiddie had recommended coating the prop with cold galvanizing, which is sold in spray cans in hardware stores. It has a 93% zinc content. The price is about $6.00 !
Before spraying, I wiped the prop clean with acetone. Then I sanded it, very lightly. This was followed by several light coats of cold galvanizing.

This is not really surpising
I have to scrape the prop regularly from May to Sep or suffer this kind of slowness

Hello All
 
Quick question for anyone on the Chesapeake. Last time on the boat, ~3 weeks ago, the diesel was working hard yet my top speed was not quite 3. No issues under sail, at least I was going faster than 3! This lack of power really made docking tough, reverse was almost non-existant. 
 
I checked for bad fuel and looked at the filters hoping for some simple. Fuel was fine. I took a swim the other day and found the prop so fouled it was hard to feel metal. Wow, it's hard to believe the growth was so bad so quickly; fresh bottom and paint this spring. I usually only motor to the channel and maybe for up to 30 min if the wind is dead. Also, I try to get out every other weekend so I use the boat if not a lot. Prior to ~3 weeks ago I didnt notice a problem but I guess it just wasnt quite as bad yet.
 
Anyone else have similar growth this year? I'll have to read up and see what I can do to hopefully limit this in the future.
 
Thanks
 
Chris
