    Default Thru hull bulk head fittings

    When using thru hull bulkhead fittings, thru things like the transom plates, for fittings like the water suply, do You Guys tap and tread the fittngs to thread into the plates or do You just drill a hole to fit and seal? what is the best method of sealing?

    Default Sealing transom plates

    Is there any good tips for making sure the TA plates get sealed really good. Do You silicone the plates on the outside only or do you silicone in and out sides? Do you run beads around and circle all the bolt holes?

    Silicone the transom then the plate, around all the holes etc. then bolt it up. clean off excess. Then lay a bead along the jet where it meets the plate and that is all you need. You shouldnt need to do inside but if it leaks a little you may need to. A good tip is to make sure you get silicone pumped into the gaps it really helps.

    We try use bulkhead style fittings (with o'rings seals & retainer nuts , no "goo" 'cept for the plates ) or we actually drill and tap fiberglass or aluminum for threaded with positive seals , makes for a very clean leak free installs , Josh makes a dozen different configurations of these Tom

    Chris thanks for the tip. I will make sure i get all the gaps nice and full.
    Tom That is what I did. I drilled and taped the plates and the fiberglass for all the thru hull fittings. On My dumps I used AN bulkhead fittings and an O ring to seal the hole. I hope that works. The an fittings are pretty slick. I fitted some an fittings on a couple of lenghts of garden hose and they conect to the dumps so I can route the water out of the garage without macking a mess and having to pull the boat all the way out. I also made a hose with a valve and an an fitting to hook up to the water inlet at the transom.

    Tom do you carry the blue anodized fittings like in the first picture and are they long enough to go thru 1/4 plate and +- 1/4 glass and still get a back up nut on?
