Removing bronze portlight interior oval ring?
« on: February 04, 2016, 02:10:33 PM »
Anyone tried to do this? I'm thinking of updating/improving the oak interior panel on the aft bulkhead in my cabin. I removed the nuts and tried to gently pry off the oval ring but it had a lot of resistance. Were these installed with a sealant? Any information would is much appreciated, especially from someone who has done this.
Thanks,
Doug

Doug,

I have had all of mine off, cleaned and reinstalled/sealed and they do come off fairly easy, although mine were on the fiberglass. It sounds like yours is on some wood??? I would go real easy with a thin putty knife and slide it in behind and see what happens, remember be patient. Sometimes a little heat from a heat gun helps loosen things as well.

Good luck and keep us posted.

Doug,

I'm having a hard visualizing this, because my ports have the oval ring on the outside.  The inner part is all part of the main porthole, which could have been originally installed with a bedding compound or sealant and later have been re-done by a previous owner.  Hopefully 5200 was not used!

Mike's right that heat could help make the sealant softer.  Putty knife will help too.  You may also be able to give it a tap with a rubber mallet from the opposite side to help break it free.

Regarding the new sealant, I have had excellent results on installing portlights with a bedding compound called Dolphinite. It can be removed at a later time with no fuss.  I used 5200 once on a previous boat, and the portlight was impossible to remove and permanently attached as far as I was concerned!  Lesson learned.

Doug,

We took all ours off about 18 years ago for cleaning, sealing and regasketing.  All were installed with white 3M 5200.  Some were relatively easy but a couple were near impossible.  The one I still remember is the one in our WT engine room which finally came out with with a lot of effort and a big crow bar.

Heat from a hot heat gun helps release the 5200 and there is also a 5200 release compound you can buy.  The problem with the release compound would be getting it to all the stuck joints.  I wouldn't put them back in with 5200.

We have replaced most of our old 1/4" oak paneling with either bare white painted hull in many cabinets, or in the case of the aft and fwd staterooms varnished wood strips.  This gives a nice finish to those large hull sides previously covered with oak ply.  If you want to have a look, see the interior pics on our Soggy Paws For Sale ad off the homepage on our website.

Doug,

Mathew is correct the ring is on the outside and the main body is from the inside.

I reinstalled/sealed mine with butyl and have installed my “new” New Found Metals ports in the aft cabin with butyl as well. I really think it the best sealant to use for this application. Check out www.compassmarine.com about using butyl. He will probably make a believer out of you.

Thanks all for the help. After a little more research, it does appear that the body of the portlight is on the interior with the oval ring mounted from the exterior. This adds a bit more work to the project but offers an opportunity to make a more dramatic change. Dave and Sherry, I like the look of the varnished wood strips. I will probably go with that. Thanks again for the help!
