- What are Sacrificial Anodes and why are they so important ?
In this video I explain what caused this Boat Propeller to erode so badly, including a kitchen table experiment to demonstrate Galvanic Corrosion. I also explain the importance of electrically connecting Sacrificial Anodes to the parts that they are designed to protect against corrosion. This is another video to help motor boat and sailing boat owners undertake routine maintenance and repairs.
Great video, can't wait to see more
Thanks for watching, commenting and subscribing. It's much appreciated. There are other boat maintenance videos on the Channel, which you might find interesting, Check out - ua-cam.com/play/PLHpRqzORk6uONy_f0M0TSPxlstENhj__x.html .
Thank you also for reminding me of, "Mad World by Gary Jules" and introducing me to, "Island in the sun by Wheezer". I hope that's where I'm going when I finally pop me clogs :-).
Excellent presentation and very clear description of the anodic processes. Best
Thank You Mark. You were on the ball today, the first one to view it and barely 10 minutes after it went public. Take Care ... Dave
Yes popped up as i sat down to my post lunch rest and read. Perfect interlude to watch your vid. And agree with other comment you have a great story telling voice. 😊
Who'd of thought sitting at your kitchen table and dangling 2 screws from a piece of wood into a jar of salty water could be so interesting 😊 Great video.
Well I found it interesting :-) Thanks for watching Kath. I'm wondering if there is any mileage in an online, "Screw Dangling Workshop". What do you think ?
Sounds like a winner to me 😊
That was a really good explanation of cathodic protection. Especially about connections to your sea cockspur etc. Really good video. Thans for sharing. ❤
Thank you Graham. It's been thought about for a long time, some of it was videoed a year ago when Zephyr IV was out of the water. Once I started writing a script, it sort of fell into place. I was so lucky to find the distressed propeller at Boat Breakers. It does sort of hone your attention :-) - Thanks for watching, if you haven't subscribed yet, I'd be really pleased if you did.. Best Wishes ... Dave
What a beautiful voice.
Well that's a very kind thing to say, thank you, quite made my day :-) A present from my Dad I guess.
@@davesailing I'm just a random dude on the internet that enjoyed this peaceful 8 minutes.
Your content is enjoyable in the same way Baumgartner Restoration is. Interesting and peaceful.
Well you are very welcome "random dude" @@unpersonableme1805
A fellow Westerly Storm? I tried the eco power and thought it rubbish. Yours appeared to work a bit better.
Hi, Considering the boat spent from December to March static on the Marina then I think it worked reasonably well. If I was staying with that prop, I would really clean it up and abrade it with a coarser paper to get the best possible key for the primer and probably add three coats of antifouling rather that two. It's a shame I couldn't get to take video before they blasted it with the pressure washer. I would like to have seen how much of the primer came detached under normal use. It didn't work at all well on the P bracket. Too hard I think and didn't erode to expose more biocide. Had a few problems here, been a bit poorly, so behind schedule. Hoping to be sailing by end of May. Good to hear from you ... Take Care Dave
Now i'm wondering if i should get one for my car...
Well not unless you have an Amphicar or maybe a Dukw. However it would be a good talking point at the pub. Cheers ... Dave
So, every bronze throughull should be wired to a sacrificial anode?
Great video btw :)
Well the theory suggests that. On my case all the bronze bits are wired back to the big sacrificial anode bolted to the hull. And none of my seacocks have gone pink after 30 years. I have a shaft anode to protect my propeller but now I've upgraded to a Feather Stream it has its own bolt on anode. You can over protect a boat but mine seems about right. Glad you enjoyed the video. I learned a few interesting things, whilst researching it. And it was fun playing around with the jar of salt water and different combination of metals..Best wishes... Dave
@@davesailing Thank you, Dave. I will be looking into non-metal through hulls and seacocks. The idea of regularly checking additional wiring is not very appealing :(
