BTW- There were no anodes on the shafts. The had a bonding rider on the shaft but that is it. Will be investing in 130mm ID zincs. Anyone know a good place to get the zincs at wholesale?

Very observant guys. The welding machine is being used for hull plating replacement. The shafts are at F&J Propeller in Miami. They will be machining and welding the deep intrusions and buffing back down on non bearing surface. See attached pictures of test area. They will be doing an overlay on...

She is an Italian built full displacement hull and can be seen at www.goldencompass.biz

Guys thanks for leading me to Brian at Aquamet, it appears the Italians put in the 17 instead of the 22HD or 25. This is why the magnet sticks to it like it does the hull plating. There is Cathodic protection and monitoring which is within the normal range. I will be adding a potable water flush...

The yacht traveled the world but now sits and waits for a new owner. I have talked with F&J propeller in Miami who will look at making new shafts with better material. Talking about turning 5.5" shafts to 130MM. How does that effect the SS once it has been turned down to size. Thanks for all of...

In Italy they supposedly replaced the shafts July 2012 for the same issue. Unless they told the owner they were new shafts and machined the old ones? What do you see that makes you think they have been machined before?

Thanks for responding guys, I like the idea of pumping fresh water through the gland while we are just sitting alongside. There is a fitting from the engine raw water cooling side that goes to the backing of the packing which could be tied into. This would push the salt water out and keep the...

Not sure why the pics didn't upload. Will try again. Behind the packing gland is the first bearing then 4 ft further is the stern tube bearing. It seems as though the bearings are trapping water. Research indicates in time the salinity increases as well as oxidation lowering the O2 content...

Thanks guys for the response. The shafts were replaced in Italy July 2012, I had to use google translator to get the basic information of replacing shafts and bearings. No other info was given on the invoice. If you look at the picture it doesn't even look like SS. I am in Miami would prefer to...

Hello Everyone, I am new to this site and could really use some information. I have two shafts 130mm with heavy pitting that I need to have resurfaced and machined. I am probably not using the correct terminology please bear with me. Some of the pitting is 1/2" deep but I have heard that the...
