Thru hull fitting

[Bouba]

Yes or it could end up a tale of woe. He can use his cheap but order a True design one and fit it later.

Yes..that’s the plan

Don't know wether things have moved on but,
1 11/16" is about 42.8mm
and googling seems to suggest it's quite a common size

This afternoon’s test fitting will tell me all I need to know...

Not to cause you any more angst but it has been suggested that someone asks you how you feel about Harry Kane moving to Bayern Munich

 

[LittleSister]

only Bouba can get a thread to 125posts on such a bleeding simple and obvious issue and STILL haven't even removed the effing flexhose...

And most of those posts are about replacing the through-hull, upon which Bouba has become fixated without any clear rationale or relationship of that to the 'rust' he observed and originally reported as the problem!

He has even made replacing the through-hull unnecessarily complicated for himself by insisting on using only a Trudesign brand one, which is neither in stock nor clearly easy to connect to the particular hose he has.

I do hope it all works out for him, but it would not be beyond the realms of possibility for all this to result in launching of the boat being delayed, and yet the source of the original problem (if there really was one) still being unidentified and unresolved.

Wot he sed.

C’mon Bouba. Deal with the rust. It’s the only serious problem here.

Better than Man United
Anyhow what do you know by the way you were right it’s 38mm

Was there ever any doubt?

I have had Trudesign on my wish list for a long time. I’m pretty sure the existing fitting is good but I am happy to change it while it’s on the hard..and next year I hope to change some more..the Onan engineer is coming as soon as the boat is launched..so not worth me tinkering with it

 

[Bouba]

The forecast for Saturday launch is very windy so I will possibly delay it

 

[Bouba]

This is the water pipe that goes to the thru hull…you can see the rust was coming from the generator side not the seacock

Those fingers need to develop a few calluses.

Nothing wrong with sensitive skin
Ok I have my angle grinder and am ready to remove the old fittings

Nightmare getting the old fitting out
Test fitting of the new set up

I am also planning to replace all the fittings with Trudesign and all my anodes to aluminum...it would have all been done by now in a leisurely fashion but we only just came back from England

It will be interesting to see how the aluminium anodes work in your situation. Might be slightly less active than zinc in a marina environment?

In the sense that they last longer (according to my research) but I am hoping they are just as effective

I’ve never tried them but I have read that, whilst they’re less toxic and capable of being very effective, they can oxidise and stop working so well if they don’t get a decent flow of water over their surfaces.

 

[Fr J Hackett]

Aluminium is slightly lower in the galvanic series than zinc so will not be as effective but whether it's effective enough I don't know. Aluminium is oxidised within milliseconds of being exposed to air and is passivated but in a strong electrolytic solution such as sea water this will be removed almost instantly so it will not impair the reactivity.
Personally I would continue to use zinc anodes for the small benefit over the cost.

My motivation for getting aluminum is the long life... I am tired of that end of year worrying about the anodes when it’s too cold to get in the water and look
