Would like some ideas on sealing transom keyhole for outboard bracket.

[Croge]

I am in the process of converting my 84 Islander to an outboard and am almost at the stage to get the bracket made but am wondering what some ways are to seal the old I/0 hole. I have a new transom put in that does not have the hole in it but am curious about the hole still in the aluminum. I was thinking of riveting a piece of aluminum smothered with 5200 over the hole on the outside and just make it small enough so that it fits inside the outboard bracket. I am not sure if I should put a piece on the inside as well because the transom is very tight sliding in as it is. Was thinking of welding in a patch or plug but was nervous about warping (and I already have the transom painted). Does anyone have any ideas? Thanks!!!
I can post pics if needed when I get home.

I saw on here someone put a outboard bracket over the keyhole without filling it in and just smothered 5200 on the bracket flanges. Not sure on how it turned out though.

Few conversions are posted as successful, some as you found, are started, but no followup @completion or performance.

I cant think of 1 well documented successful conversion.

Maybe this 1 can be the 1.

Jasoutside did a working conversion and one other member as welln but I don't remember who it was.

I think Jason's was one of his Islander re-dos. He went through a few versions before selling it. The buyer, alipinski397, finished her up.

So anyone that followed Jason's most recent update on his thread for the 22 Islander build, you now know it found a new home with me. Given the epic build thread and history on it I felt i needed to start a new thread continuing the legacy. I think a little back story on how I ended up with...

Hey, fellas... Look what I found! I ended up having a snow day on Friday so I decided to go down and check it out. She was located at a scrap yard and the asking price was $700. The owner was a heck of a nice guy and we chewed the fat for a bit, haggled some, and I almost walked away from...

I think Jas passed thru Islander was an OMC to Mercruiser conversion not an I/O to OB conversion wasnt it?

But I suppose OMC hole treatment could be considered similar.

OMC Stringer 2.5 4 cylinder to Mercruiser 4.3 V6 to Mercruiser 5.7 V8 to a bracket that was finished by alipinsk1 with an Evinrude 175. It went from an Islander cuddy to an SS clone with Jason to a center console with alipnski.

You sir are correct, thanks Don. JC

Now that its percolated thru the fog, Marmaduke did a big ole boat to OB bracket he built himself. Dont recall him coming back to finish it, did he?

 

[GA_Boater]

Marmaduke doesn't ring a bell. I wanna say the other one I'm thinking about is by a member name starting with a "t". The one I'm remembering was a bought bracket and it was finished.

Something is coming through - Was Marmaduke in Alaska?

 

[jbcurt00]

Marmadeke maybe.

IIRC, Michigan... had a giant shop. Had his son & daughter involved a bunch.

Scrapped his 1st SC project. Cut it up into 2X2 pieces to maximize per pound price.

His I/O conversion was also a 26ftr cab/cuddy cutoff conversion I think

Yes alipinski397 was the one I saw and one of the few builds that really made it to the end. He just told me it works well so I am very happy to hear that. I think then with a plate over the hole on the exterior riveted with 5200 on it and then the bracket over it bolted through and 5200 on it I should be good to go. It is a slow build that I work on when I can but I hope to be one of the ones done and enjoying it some day!!

No wonder I was kicking my PC for not finding marmaduke. LOL

I remember him maxing out the scrap price with the small chunks. I think some of it ended up in the new build. He kinda tapered off like too many do.
