My parents quit using this boat over 20 years ago because the transom rotted out. We did a temporary fix to the transom last summer just so we could make sure the engine worked. Turns out the engine is in great shape, so now we have to do the real repair.

After doing a lot of research we decided Seacast seemed to be the way to go. So, this weekend we started the hard part, the prep work. Cuttung the top off the transom was pretty easy because it was completely cracked in the back. My saws-all worked great for that. I naively thought we could complete the prep without buying a chainsaw. However, I broke down fairly quickly and bought one. I have no idea how you would prep the transom without it.

Of course, we ran into a few snags. Taking out all the rotten wood left some gaps between the existing fiberglass and the good wood. I also made the stupid mistake of cutting a hole in the bottom of the hull. It actually made it a little easier to get all the saw dust out of the transom, but I'm pretty nervous about the hole. Our solution was to use a fiberglass cloth to cover the gaps and the hole I cut. We then put several layers of duct tape to make sure it molds properly.

Based upon Seacast's claims and testimonials on their forum I think we'll be ok. Anyone have any tips/suggestions? The hard part is over now, I think. I'll post some pics when I get them down to size.

Use the search function and search for Seacast and look under the member of Gary H NC

He did a seacast transom and you should read about his. He experienced and air pocket and gives great advice.

Re: Invader Intruder Transom

Have You Considered Using The Nidabond It Is Considerably Cheaper Then The Seacast. It Is About $ 120.00 Per 5 Gallon Pail. From What I Have Found On Iboats No One Has Used It So Far So I Guess I Am The First Time User Of The Stuff Which I Still Have Not Used It Yet. I Have It Aready I Just Have Not Finished Removing The Transom Core. I Am Hoping To Pour Next Weekend If It Is Nice Weather.

I haven't heard of that. Let me know how it goes when you get a chance to pour.

After looking at the pictures of the rotten wood in the transom I can't believe that the motor stayed on there for most of the summer. I'm lucky that it didn't fall off when I was following you on the way to the lake! I can't wait for the Seacast to get here so we can finish the transom and get it back on the water!

I Dont Know If You Ordered Your Seacast Yet But My Transom Is Done With The Nidabond And It Went Very Well And Was Very Easy To Work With. See My Post Under Transom Repair

Whoa, huge images. Sorry about that.

Re-size your images to 640 x 480. That is our size limit here on iboats.

You appear to be making progress!
