Boat transom project - Fritzfishin - 03-18-2022 Some may remember my post from a few months ago about my transom in my boat I thought it was rotted out... finally this weather and pictures of catfish and walleye from this time last year lit the fire under me...  I cut the aluminum top cap off the transom and was shocked to see what was in there,  I pulled out about 2 five gallon bucket of rotten moldy sawdust,  after getting it all out and cleaning it with some 409 I finally today cut my new transom out of 3/4" oak plywood, I predrilled all my holes and screw holes ill need and just got the first coat of waterproofing stain on it, I know it won't last forever but it'll last long enough. Tomorrow ill get another coat on then glue and screw it all together. Its a VERY tight fit I almost couldn't get it out after predrilling the holes, lake point custom fabrication in erda is going to weld it all back together once im finished.  Seemed like this outta do decent for what I need This is what's been holding the motor on RE: Boat transom project - MSM1970 - 03-19-2022 Good thing you done it now, looks like it was about ready to fall off, you will have goo piece of mind now anyway, RE: Boat transom project - MrShane - 03-19-2022 You did it the right way and it looks like you did a fantastic job! RE: Boat transom project - BearLakeFishGuy - 03-19-2022 Since you did not use marine-grade plywood (where there are no voids between the laminations), you really need to seal those edges. I would use a filler and make sure there are NO voids where water could enter the edges. I did my transom like this about 15 years ago and its still going strong on my old boat that I sold to a friend. I did my research and the marine plywood was difficult to find and I had to have it ordered in, but it was worth every penny. I then laminated two, 3/4" sheets together with the 5200 marine sealant. I used stainless screws/bolts to reattach the aluminum "skin" and did not have to have anything welded. The real trick was to seal the ends completely to exclude any water/moisture. You're doing a good job. Did I mention, make sure to seal those edges! RE: Boat transom project - Fritzfishin - 03-19-2022 I have some new silicone type product I was gonna coat all the edges with once it's screwed and glued together. Would it be fine just jb welding the top cap on or should I spend the money and have it aluminum welded back on? I've hit the edges and all the wood 3 times with the waterproofing stuff I figure ill just keep doing it till I run out RE: Boat transom project - Fritzfishin - 03-19-2022 Several coats of waterproof plus extra on the edges, about 30 stainless screws, liquid nails evenly spread solidly through the 2 sheets, then I smeared liquid nails all the way around the edges just thinking it might help. If it lasts 5+ years I'll be happy, I'll silicone over the screw heads after I decide if any need to come out to get my bolts through it to secure it back to the boat using the existing holes. RE: Boat transom project - Therapist - 03-21-2022 HEY DUDE!! Don't seal it yet!!  Go to Home Despot and get some epoxy resin!  It is a two part resin and coat the plywood with that, both sides, both ends, and both edges.  It take 24 hours to cure and you should put 2 coats on.  I had to make a platform for my rig and I used that before I carpeted it.  It will seal the wood and give you a lot less trouble.  Can you laminate your plywood with two sheets??  If so,  I would suggest that.  You transom may be to narrow to do that.  But use the resin on it, seals the wood and gives it some extra strength !!!  Good Luck!!
