Does anyone know the size thru hull I need to, get I am adding the merc water pressure dump valves

Here is the link to the ones I just ordered and install for my pressure valve on my Fountain.I went thru the side right next to the bilge dump.If you want to go out thru the transom then you will need a longer threaded part.

I did go through the transom, but don't remember the size. Certainly took care of my water pressure problems.

Any picturess of your install

Just left the Lake. I'll try to get a picture the next time down.

Did you end up bitting the bullet and buying new? Sure as heck don't look like they should bring the high price, but well worth it once all is said and done.

I think I posted pics before of mine where I welded bungs into my silent choice valves so I wouldn't have to add thru hulls for the valves.
