Thank you toholthe,
Said that my waste hose is still in good condition, yes one option is to change also the hose and I'm not afraid to enlarge the hull hole, instead I would not open a new window just below the waste tank to have access to the hose connection, how did you replace the hose?.
Nevertheless, if the current waste hose is already 38mm ( and it should be because I read that tank output is 38mm)  I wouldn't have problem to use a 1 1/2" but what look strange to me is that I don't see tapering on the hose connection on my current 1 1/4" (32mm) valve.
Unfortunately I'm not near the boat to take measure.

Hi Alb_mo,

you can have a 1 1/4" valve with a 38mm hose connection. I believe that is what is installed originally.

Worried by the horror stories of through hulls and valves breaking apart, I finally replaced them with trudesign. Used a (real) bronze 90 degree for wastewater (inner diameter of trudesign too small).

Just for information, all the low quality std. fittings Hanse had used were still in great shape.
See pictures. No dezincification at all. I actually decide to hit the wastewater set up with a hammer repeatedly to see if it would break/crack, it didn’t, only showed a dent.

2007 400e, in fresh water year around, salt water 2-3 months of the year.

Surely many people had real bad experience, just wanted to balance this by mentioning it’s not all bad everywhere.

I’m happy I did the work, for peace of mind, but with hindsight it wasn’t really necessary.

Regards,
Peter

I would like to change the valve on my SD50 saildrive to TruDesign. Not able to find male to male connector in reinforced plastic here in Norway. Only in NZ, but postage is crazy. Is there problem with using a trudesign thru hull, cut off flange and use the threaded part as male to male connector?

Btw, anyone can confirm dimensions of male to male connector for SD50?

That is exactly what I did on my SD20, replacing the standard Yanmar gate valve which only lasted a couple of seasons before seizing up. I did it two years ago and had no problems yet!

I have finally changed the cooling water intake to Thru design on my 370 with SD50. There has been numerous post on this, I did it this way: I have not found a male to male connector to go into the SD50. Instead I used a male to female 90 degree connector. I had to cut away approx. half of the threads on each side to be able screw the connector into the SD50. Then I used a brass male to male connector between the bend and the ball valve. The brass connector is an ordinary one that is used for plumbing. According to specifications it should not release zinc, hence less corrosion. I had to remove the ball valve handle when mounting the valve (there is a center screw on the handle).

If you read the post from Rock, it seems that sailors from the fresh water in Ijsselmeer have no problems with corrosion of the thru-hulls.
But if you are sailing in salt water like the most of us, things are different.

HPNielsen DK from Denmark today has posted a picture of the seacock from his holding tank. This photo clearly shows, that if you are sailing in a boat from 2006-2010 with the brass seacocks installed by the Hanse werft, you are gambling with your life as well as with the life of your passengers. The price of Trudesign seacocks for a Hanse 400 is €350. Is your life worth that?

I changed the seacocks in 2013 when they were 7 years old. Look at the pictures of those seacocks, compared to the seacock in HPs Hanse 400, which is 15 years old.

Does anyone know what the 2007 Hanse 400 had? Also, any way to test the things, preferably without banging on them?

My H400 2007 had:

 Waste:
1,5" throughhull
1,5" 90 degree
1,5" valve
1,5" hose connector for 38 mm hose

Toilett inlet:
3/4" through hull
3/4" 90 degree
3/4" valve
3/4" hose connector for 19mm hose

Shower out:
3/4" through hull
3/4" 90 degree
3/4" valve
3/4" hose connector for 19mm hose

Galley:
1" through hull
1" valve
1" hose connector for 25mm hose

If you originals on a 2007 you should change them. It’s a quick job and gives ease of mind.
