Transom problems with older G3's ?

Has anybody heard of this?

I have a transom that is popping corrosion holes in the transom.

Found out this is a common issue due to the chemicals in the marine plywood used.

My buddy who has the exact same year hull has it too. 2002 1756

Seems from what I read G3 knew about this issue, but stayed quiet hoping the 5 years would expire before it "came to the surface". If that's true, shame on G3!

I was quoted $1100 +/- to replace this by a reputable metal boat builder.

Funny how G3 quit using plywood, unh?

I have heard this before, I believe on tinboats.

Contact G3....Those boats have a lifetime hull warranty for the original owner.....they should make it right. They replaced a boat for my neighbor.

I, like many, am not the first but third owner. This boat was in excellent condition. It still is as no dents or cracked welds, just a deteriorating transom due to no fault of mine.

Still I would contact G3..and talk to them,, they might do something.....you have nothing to loose

It only costs a phone call.

These boats originally had a 5 year hull warranty as stated. At 6 years G3 replaced one for me with a small crack. They sent me a new boat after I brought to a dealer asking how I could repair it. He called G3 and they sent me a new hull within two weeks I was shocked. They are a great company and stand behind their products. That being said it sounds like either saltwater or electrolysis on your hull. Plywood was used for many years on aluminum boats and I have never heard of an issue due to plywood treated or not. They quit using plywood due to weight and using a thicker aluminum and also made these rigs all welded. I would consult G3 on proper repair, they may offer help. Though, the boat is 13 years old almost three times the warranty period. Sorry to hear of your problem and hope it's a easy fix.

I always wash the boat down after a flats trip. There is NO corrosion anywhere else.

There are WAY too many identical transoms with this same problem to be isolated.

The plywood is completely surrounded by welded aluminum. The holes forming are not near any penetrations in the transom.

Use google and you will see. I believe they neglected a recall that should have been done.

And salt will eat anything. I lived in the North and fought salt corrosion on my cars my whole life. Salt is nasty. just sayin'

I'd be amazed if they fixed a 13 year old transom, but like was said earlier, it's definitely worth a phone call. Product Liability insurance is expensive, and it might be cheaper for Yamaha to fix it opposed to having a future product liability suit.

Being a great company, they usually will help. The age of the boat, and you being the third owner will affect their decision tho.

I've fixed many of these over the years (not just G3). Aluminum boats have been made with wood transoms for a long period of time. In earlier times, they didn't even use treated lumber. Later, the treated materials they used contained chemicals that caused issues with the aluminum. In the boat manufacturors defense, they usually have no clue of the chemical materials or compounds they get when they purchase the wood materials. Each company that makes the treated lumber uses slighly different compounds that can oxidize aluminum.

We stopped using Marine Grade plywood on our replacments a couple of years ago. The price, weight, and material compounds just didn't make sense. Besides, reading the fine print talks about the sunlight directly effecting the shrinkage of the materials. Marine Grade tends to have more moisture in it. Couple that with sun, heat and humidity (all things found on a boat) and you can see the problems.

We switched to the newer AC2 treated materials. Lighter, stronger, less harmful chemical makeup.

Like others said, it doesn't hurt to ask them. They might have a fix for you. If not, you could do it two ways. Do the work yourself and change out the plywood with new material or..... purchase the metel and replace it with metel. Another good option is to utilize polymar material. Good luck.
