Transom issue need help

[Boatboy6]

I could never see how you could get a good bond using a pourable transom, to me it just seems like you could never prep the surfaces correctly.

It's easy. take off the transom skin, remove the mush and prep the inside and outer surfaces properly and you WILL have a good bond. One of the secrets to the Arjay is how they are able to keep the cure temperature at a steady level, I think 180 degrees, not positive of the number. If you poured that much mixed regular fiberglass resin in a closed area the heat would be crazy. When I did my 23 I was amazed how thin the inner skin was, basically a moisture barrier, the transom skin was a different story.

Thank you for the help I'm adding a Hermco bracket and enclosing the transom can't wait to see how she comes out. I will post some pics when she's back in action

I never liked pourable transoms either but do think they work well tho.

Long as you got good glass on either side of the core, the center core don't matter as much. Most of the strength is in the skins on either side.

I started believing in it more after the scarab with the triple 400+ HP outboards did his with that stuff. He has like 1200 HP and over 1500 lbs of outboard on his and can run 80 something and hasn't had issues with his poured transom yet.

Would I ever do one, NO. But are they a method that will work and suffice. YES

I'm about 95% ready to do the pourable transom. I took the outer skin off in order to remove the mush that was there but to also have the inner and out skin that will be in contact with the pourable nice and clean. I plan to go with Arjay and I should be ready hopefully by this weekend and if the weather holds out.

And I agree that it is the prep work that makes the difference ...and on this one I have been more that diligent to the point I may be over doing it.

The main question I have is how much and what kind off glass do I use on the outside to have it nice and strong and smooth ?
