BOLT HOLES IN TRANSOM

I'm putting on a new transom setback bracket for the outboard motor. The original mounting holes cannot be used do to different mounting bracket hole configurement. My question is what is the best way to fill in the existing holes for the best possible strength to keep the original integrity of the transom? I've been told dowel plugs with JB weld for a sealer works well. Other remedies would surely be appreciated.
Thx

I used Epoxy Resin mixed very thick with Aerosill( ground fiberglass) So thick it wouldn't drip off the mixing stick. I placed the stuff in an empty caulking tube, regular size caulking gun. You should drill the holes for the new plate larger than the 1/2" bolt, it doesn't have to be alot . Then put a very good coat of the same mix in that hole & drill again to proper size if you have too. That way water will pass through without getting in the Transome. Ofcourse there's more than one way to skin a Cat! Good Luck SAWCAT
 
I used the same method when I had to fill the holes in my brand new transom ( don't ask, was not a good day) Works very well.
 
As an alternate, you might be able to use the existing transom holes and modify the jack plate. I've heard of more people doing it that way.............
 
I first was going to refer you to my rig, but it looks like you have a 90's model boat with 90's model motors. What do you have that has a different bolt pattern?

I HAVE A 93 PULSE 211 WITH A STAINLESS MARINE SETBACK THAT HAS A DIFFERENT BOLT PATTERN THAN THE CMC JACKPLATE THAT I REMOVED.
TRYING TO MAKE HER GO FAST,TRYING A 23 INCH SETBACK WITH A 300 PM.
I HOPE THIS WORKS FOR ALL THE WORK TO SET THIS UP.
SEE YA CHECKMASTER
 
i will always recommend cutting a dowel to size and using a filler for a hole any bigger than a n eighth of an inch.
