Transom Replacement
The next step in my Jet Boat Rebuild, is to get the new wood for my transom installed. I cover the process that I used to epoxy in the new ¾ marine grade ply wood. If you are doing this repair yourself I would highly recommend that you use marine plywood. It is laminated with better adhesives that will be less likely to delaminate if moisture is present in the wood. Also the wood is made with more veneer layers, which are also selected to have less knotting in them. The wood is a much better choice to use, but it is more expensive than standard wood.
I cover the techniques that I used to get a quality template for the new transom wood, and how I was able to cut that out on the wood. I also go into some detail on how I went about fitting and fine tuning the transom wood to the boat, ensuring a snug and tight fit.
When it came time to bond the wood to the parent fiberglass of the boat I chose to use an epoxy. I used the G-Flex 650 made by west systems. I also used the “403” additive to thicken the epoxy up, so I would not have as much sagging and run out.
Once cured I tabbed the new transom wood in with one large piece of 1708 biaxial cloth with vinyl ester resin. I also applied one more layer of 8’ wide 1708 around the perimeter of the transom.
At this point I will be leaving the transom as is. I will continue with the installation of the rest of the wood in the boat. Once I have all the new wood and stringers installed and tabbed in, I plan to go back and address the cosmetics of the glass work.
The products that I used in this video are listed below:
Fiberlay Vinyl Ester Fiberglass Resin (Used to glass in the 1708): fiberlay.com/pub/media/sparsh...
Fiberlay Fiberfiller Structural Putty (Used to fill voids behind the transom wood, and to fillet the corners): fiberlay.com/pub/media/sparsh...
West System 403 Microfibers Adhesive Filler (Used to thicken up the G-Flex Epoxy): www.westmarine.com/west-syste...
West System G-Flex 650 Epoxy (Used to bond the wood to the fiberglass): www.westmarine.com/west-syste...
My goal is to try to keep the detail high in these videos, while also trying to keep them from getting to long and drawn out. So I will try to break these videos down into smaller segments. So if you haven’t, I encourage you to subscribe to the channel so you can be notified of the new videos coming out. I hope that you find this series of videos to be helpful for your project. If you have comments, suggests or tips that you would like to share please leave them in the comments section!

Sweet job on the transom. I am SSSOOOO glad I found your channel, now that the weather is cooling off I am getting ready to replace my stringers and transom so your video series is SO much help. REALLY looking froward to your next video about the stringers. Liked and Subscribed!!!!
I just found you’re channel. When I saw what you were working on I was like no way. I’ve got an 83 Centurion Warrior which is basically the same boat except with an outboard. Pretty much doing everything in the boat transom, stringers, and bulkheads. So far I’m done with the transom, and cutting stringers today. I was just searching stringer videos for ideas and you popped up. Looking good!
Clear packaging tap works really good, resin does not stick and it leaves a smooth finish when peeled from a repair. You should try it.
Time for a Silver City beer!
Great work. I replaced all the Balsa in my 18 tunnel jet drag boat and am about to start on my 19 placecraft to bulk it up for lake duty. It's a potato chip. Great content brother!
When I do a transom. I use ram board to make a template. I also make the template on the outside of the transom.
Excellent progress and amazing work as always!
Don't complicate it. You'll be filing entire area with thickened resin anyway. Doing great job though. I just finished my 3 year complete restore. So much work.
I know I am way late but I'm thinking transoms on jet boats take alot different stress than a outboards or io s
So is the one sheet of 1708 and then tabbed in the all you are puting ? I am going the try to do the transom in a 76 cobrajet its gone it doesn't look like it had anything over the wood idk 😂 I am just trying to get an idea of how many layers and maybe a ballpark on what it cost you thanks can't wait to see it in the water looks great
U have a stinger install video
Good work man, lots of good tips too, just one question for now, we’re did you buy the fiber glass?
I need your help.
