We will be replacing the through hulls and sea cocks on our 2010 400 in a few months, does anyone have a list of sizes for the through hulls? we will do our own count and measuring, before ordering, but it would be good to have a check-list in case we forget one!

Thanks

Thank you very much Stein, we'll do our own count soon. Is there one for engine cooling water?

In page one of this thread you can see a post from StavrosNZ, where this thread is mentioned:
http://www.myhanse.com/sd20-saildrive_topic9673_page1.html,
Stavros informs, that the " nipple (male/male) is not manufactured by Trudesign, (but it's OK to use bronze instead).
I can recommend the "search" -function here on myhanse, new members can find a lot of answers to their questions there.
Trudesign is just one of the topics there, all types of solutions can be found there.

You used the epoxy on the outside? Why not just Sika?

I am planning to change the tru hulls on my Hanse 400 2007 mod to TruDesign. Have anyone gone for the flush skin fittings. Is the hull thick enough without strengthening inside? I will use epoxy for gluing fitting to hull. 

How do I use the router to make a recess for the fitting like on the picture? Any idea?

Hello,

a ship yared just changed my thru hull to flush truedesign ones. I have an Epoxy boat and they told me that the laminate was not thick enough. That's why they glued in stiffening rings on the inside. 

The installation looks good now however the boat is still on the hard!

Ok, I will not go for the flush ones then in fear of being to weak.

Hello all,
I follow this intereresting forum from 2018 when I bough my H400 2007 but I never partecipate before.
Now I'm in the process to replace my seacocks with Trudesign and reading the post from Stein I had a doubt regarding waste valve.
In my boat is installed a DN32 - 11/4" instead Stein mounted a 1.5"-38mm, that in my view it should be an 11/2" - DN42, quite large to fit my 32mm waste pipe.
Stein, did you have originally fitted the 11/2" or did you replace also the waste pipe or I missing something ?
Captain Cook, which waste valve did you install ?
Many thanks in advance.
Alberto

I just did the same on a H400 2007. It was installed a 1 1/4" on mine as well. I replaced it with a 1 1/2" as this is the standard for waste. I had to make the hole a bit bigger by a manual file. Took only 5 min.
I am quite sure the hose is 38mm, at least mine was.
