For thos that have done pourable transoms?

I also used Arjay and had excellent results. It is easy to drill and shape, but be sure to resin and cloth those holes as nymack suggests, I tried the duct tape and it did hold on all but two holes. The two holes it didn't hold on created one heck of a mess. As for the cap and up the sides, I used some old paneling to form up the top and poured from the highest point and it worked very well. I found Arjay very easy to work with.

I've only got the one hole to really worry about where the livewell pump went, and I think I will do a wooden dowel through it then some sealer around it to prevent any from leaking out around it. The other small holes I can go ahead and use some fiberglass filler patch on as they are only #6 screw holes, and the 4 1/2" engine mount holes I may try som,e metal ducting tape on as it holds tighter than duct tape does.

Ferm the heat will peel it off it gets very hot, seal it with resin plus the fresh resin creates an excellent chemical bond between the skin and Arjay whatever way you go remember this stuff flows like honey :)
Here is an example how this stuff bleeds through even with resin and cloth on the inside ..

Heavy duct tape. Don't forget both sides of the holes. Yo udon't want to fill your bilge up with this stuff. Seal even the smallest holes or it will ooze out. No need for dowels. You can drill it out very easily. Two years into it I am very satisified with the results.

I ran into some serious snags on this transom so it is on hold for right now. The wood in it was sandwiched together with 3 layers of cloth and screws every 6"s across the bottom, sides and top. I got most of it out, but the bottom portion has turned into a nightmare so I am going to have to cut the skin off from the outside and clean it out.
