Jack Plate Install - Gap Issue
Posted on 9/13/21 at 11:11 am
Posted on 9/13/21 at 11:11 am
I'm trying to put my jack plate on an old Alumaweld I bought over the weekend. The transom is aluminum on both sides, wood is welded up inside the layers. When I tighten down on the bolts the outside is not sucking in tight to jack plate. I haven't put any caulk or 5200 on it yet, just fitting it up to see if it works.
I know the correct way to fix this would be to cut it open and put a new piece of wood in there then weld it back up. I'm trying to go hunting this weekend, though. Any ideas? It's rock solid with no flex on the transom. Could I put a few rubber washers in between?
I'm kind of leery of running it with the jack plate only making contact in a couple of spots.

The transom is bowed?
What about a layer of that horse matt you can get from Tractor supply?

Looks like the transom has a curve, jack plate does not. You have 4? bolts, I'm guessing. If there's a gap at a bolt interface I'd shim it with something; you don't want that thing flapping around. If there's a gap in between the bolts, which is what it looks like in the picture, just caulk it. As long as you have 4 snug contact points with no gap what happens between the bolts is just cosmetic.

Good deal, that's what I was hoping. It's snug and doesn't have any give in it. I'll shim it with rubber washers and liberally apply 3M 5200 around each bolt. I'll fix it up right after hunting season.

DO NOT use 5200 if you're going to take it back off to fix it after hunting season. If you're just talking about sealing the bolt holes for water intrusion use plain silicone. I've seen 5200 delaminate fiberglass, tear plywood trying to take stuff off, etc etc. Don't use that stuff unless you want it to be permanent.

Good point, I had to pry it off of my other boat.

4200 is for stuff you may want to remove later. Both are sealers and adhesives, but 5200 is more adhesive than sealer and 4200 is more sealer than adhesive if that makes sense. Both do great jobs for their intended applications.

My first thought is your bolt holes through ransom aren't large enough.
If they were and proper washers are used, the transom is going to pull to the jack plate at, at least the 4 bolt locations when tightened.

I think you will be OK running it minimally. after using try to cinch down on it more. may just need a little torque to pull it flush

Usually you'd be right. This transom is wood welded between aluminum. The wood has rotted away and an extra piece of 1/4" aluminum has been added to the inside to reinforce it. When you tighten the bolts the aluminum on the outside does not pull in.
I guess i could get elaborate with it, drill a bigger whole in the inside later, put a washer and spacer inside to push the outside to the jack plate.

I wouldn't run it like that, but I have seen worse out on the water.

It feels solid, just not sure if it'll hold water.

Drill holes for additional bolts in the bend to try and pull it together.. Big washers on the front side of transom.
My transom looks just like that.

so you drilled oversized holes and put extra bolts in that pulled against the outside?

Drill a slightly larger hole on the inside than the outside hole. Cut a piece of aluminum or stainless pipe the thickness of the transom. Place that through the inside hole until it makes contact with the back. On the inside place a 1/4 thick plate of aluminum over the holes with the holes the same size as the holes in the back. Run your bolts through and you would not be able to crush the transom no matter how tight you torque the bolts. Seal everything from water intrusion with 5200 or 4200.

[/img] crude drawing of what I thought of doing with bolts/nuts but I like your spacer idea a lot better.

Drilled an oversized hole on the inside of the transom and slipped a washer and a piece of half inch pipe over the bolt. It tightened the transom snug against the jack plate. I'll find out if it leaks tomorrow morning.
Hopefully this gets me through hunting season.
