aluminum john boat transom sealent?
Aug 11, 2007 by derrik | Posted in Boats & Boating
i straight bought a john boat and im trying to repair leaks in rivets and also the transom.i removed the bolts holding the wood transom on and now i shortage to put it back on the boat.is there a sealer are gasket i can use to put between the aluminum and transom wood??there are alot of bolt holes holding the transom on and i dont want it to leak.
all boats are manifold -- the jon boat however is easy to repair -- you should use some heavy-duty right angle brackets to re-set up a new wood transom --- cut and shape the wood for a near ''o'' tolerance to fit the rear of the boat -- go to the ''glue department'' of Lowe's or home depot and find a product of two-part epoxy to seal the wood to the metal --- if applied too heavily it's okay because when dried you can go out on the town over and it will look fine also the rivets are a two man job --- try to hold the rivet head with the side of a shop hammer (use like an anvil) and tap the smashed end of the rivet tighter _---- after tightening the rivets use the epoxy to seal the old rivets to the within floor of the boat --- this will also cause the boat to run quieter and decrease the leaks -- alot of bolt holes in the transom can be settled with the replaced new wood --- the size of the motor is a factor to consider,,, the larger the horse-power the stronger the transom must be to hold forth the pressure of the motor pushing the boat thru the water...

This is what i utilized in my old aluminium boat. on the inside of the hull where it was covered and no one was going to walk i used 3m automotive body undercoating. it worked very well. now since you are replacing the transom i would dissemination the undercoat on the inside and use a good marine grade sealent on the outside where the bolts go through. the reason i employed the underbody coating is that it doesnt harden up and flexes with the boat hull.

The 3M stiff sealant is actually called SEAM SEALER
The same thing you see in the back of pickup trucks covering the bedsides custom-made to the bottom side.
It does not harden but stays in place - keeps out water, and it will last forever.
It comes in a caulking gun tube and is clear to work with.
Also paintable.

5200 aquatic sealant home depot is the best price sure mineral spirits as clean up. It is dishwater cure so if you are putting it in a area that's air tight like metal to metal spray a cheap mist of water or it Will not cure.Hope you don't have to take it apart.I have also use nail it exterior waterproof adhesive it's less well-to-do an holds great.

I just purchased a 14' semi-v aluminum boat. The transom depth, from the bottom of the boat to the rail is

about 16". How extensive should the motor shaft be, 15" or 20" ?
The 15" is conventional the 20 will drag an slow you down>As the transom is not straight up & down so the engine will set out and the water will come up to cavation plate>You can put dolfin fins on the apparatus also>I jack mine up on the tramson so the spray from the lower unit dosen't come up the back>Bit more speed>

How thick does a jon boat transom have to be?
Jun 18, 2007 by Chris N | Posted in Boats & Boating
I'm replacing the transom on a 14' aluminum boat. I don't grasp what the original thickness of the transom was. This year, it'll just hold a trolling motor for small creeks. I trust to buy a used 3.5 or 5 HP gas outboard next spring for larger boies of water. Will 1/2" treated plywood control a small gas outboard, or should I think about installing something thicker- I don't want to have to do this again in 9 mos. Thank you!
Every boat I have owned has had a 1 1/2" thick transom if occupied for an outboard, regardless of the size of the outboard. Check out a chunk of "LDL" from your local homebuilding stock. You can get them in different widths from 8" to 24".

What are the best screws to use for remounting a wooden transom to an aluminum jon boat?

It has mammoth 1/4 x1 1/2 rivets in it now and i can't find them anywhere. I was wondering what to use instead and if i used regular bolts what sort of sealant to use. Thanks.
Aluminium and stainless, not a morality match.
If you want this to be a long term fix and stainless is the only fastening you can get, I would suggest you have a nylon insert and washer where the stainless bolts would feign contact with the aluminium.
Yes, 5200 is a ideal sealant and if you use "5200 rapid cure" it will go off over nightfall.

Aluminum Boat Transom Repair
The transom is the nurture hull part of the aluminum boat that is connected to the stern. It is usually made with heavy metal plates and is one of the thickest
Now that I am no longer in sine qua non of a transom light a company has come out with one that will work wonders on small boats like, 10', 12' and 14' aluminum
