I've never seen zinc's on rudders. Is that OEM?

So, the Cruisers 477 I looked at had them and my 450 EB has them. My only two data points, but I can look around the yard when I launch today and see what the other boats have.

When you Google rudder zincs there are plenty of listings???
 
Kevin,
Your boat looks fantastic! I can’t wait to hear about how it runs with the prop change.
On the rudder topic, here is my boat at haul out. No zincs:

Mine did not. Pic last June on haul-out for bottom job.

Note the water line way to low, raised to 1/4" below boot stripe, also replaced.

Yeah, guess mine were added by someone some where down the line. I am only the third owner.

For sure, assume they can't hurt. I can tell you that my bonding system got some serious attention over the last month.

One of the previous owners did some odd stuff with the rudder logs. They had bonded directly to the yoke that went around the rudder post, which of course breaks often because it moves. I moved them back down to the flange on the post(where the previous two ring terminals were) and ohmed put the whole assembly. I would venture a guess my galvanic isolator is toast and the previous owner was having corrosion issues and instead of fixing the actual problem, they added more zincs???

I need to pull the isolator and check that as I stayed in a marina one night on NYE and my diver said, "I don't know what happened, but your zincs are shot."

Odd is right on the bonding wire but adding zincs no worries. Wonder if a way to diagnose that isolator. I have one, no idea if it's functional, it's just a box .

Had found this article awhile back.

GIs fail grounded so you don't lose ground, but you are no longer isolated from the galvanic cell. I don't spend hardly any time in marinas, so I had been putting it off.

Thanks. I have an IT (prev owner), Isolation Transformer. It's a Charles C-Power Isoboost 50. No indicator lights or anything. Sits elevated in front of the Genset making for very difficult access to the Racors and front face of the engines which face backwards of course. The IT is elevated so to crawl under to access the aft seacocks.
 
FWIW, I've never had zincs on my rudders or shafts of any SR I've own. And no issues <knock on wood>.

Also, mine comes out of the water tomorrow. For the usual, plus pulling the shafts for new seals & cutlass bearings, and a new chirp transducer.

I did seals too, make sure you get the right ones as most boat yards don't realize PYI prescribes an undersized carbon seal for our boats. PN 02-200-312US. It is the US extension that is important. I ordered mine and handed them to the yard to ensure no screw ups, had to special order through Citimarine, $454 each. They are $650ish straight from PYI.

I wanted to do transducers, but not in the budget this year.

Will have to make note. These are shaft log seals, correct?

Yes Sir, shaft logs.

Mine were 1 year old and leaking. Called PYI, gave them the PN my sellers yard used, same as above minus the US.

PYI said, "Yeah those will never work on your boat."
 
So, spent too much money and had to drop floors from this year's spring spruce up. Means I had to keep my carpets good for one more season. Pressure washing 2" at a time. Took a bit.

While they dry, time to polish.

The carpet looks like it is in good shape! I am trying to hold out on replacing my canvas and isinglass until next season. I have one spot on the sunshade for the aft sliding glass door that is deteriorating quickly and may not make it. Crossing my fingers it will hold on. o_O

What color (looks tan) my blue canvas is 4ish weeks out. My helm Bimini top, sunshade, and gap panel are all just two years old and plan on selling.

Not sure if/how many folks would be interested, but since mine are new and curtains are old I guess people do piece-part replacements.

Wish I had snap-in carpet in the SR's & under the dinette. Salon is hardwood with a runner. On my other boat, 1988 Sea Ray Sorrento 25, used snapincarpet.com to replace cockpit and helm carpeting. They sent heavy plastic sheeting to make a tracing. Had 5 sections. Came bordered with a snap tool and snaps to crimp them where needed. Gave three weeks to return the tool. Turned out perfect. It replaced indoor/outdoor dark color (hot on feet) garbage when bought her in 2000.

Yeah, I am confident the master and mid-ship are easily replaced with LVP, but that aft...yikes.

I have left over LVP from my house and when I find some more spare money thinking of getting salon and hall done in LVP. My carpet is in great shape, it's just crushed from having protectors on it for 22 years. Thinking I can wait on the state rooms for a few seasons, thanks to my carpet protectors. Ha, there is my foot print as I ran to the head and my kids rubics cube.

My bimini top is actually in good shape. I'm guessing the shade that is falling apart was exposed to the sun in the covered slip it was in. If your canvas is the same color, I would be interested in it. I would describe my shade as bronze, not tan. In this picture you can barely see the spot to the left where the shade is failing.

Just snapped this for you...linen tweed is what the OEM calls it.
