Random Quote: A bad day on the water is still better than a good day at work...(:
I can't really tell from the pictures, but it does not appear the aluminum fuel tanks have been zinc chromate primed or have any kind of protective coating at all.
As the tanks are obviously foamed in place, this means the bare aluminum is in direct contact with the foam. When the foam absorbs moisture, and becomes wet, something called poultice corrosion happens, which is a chemical attack on the tank. This is not good and can cause a tank failure (leak) down the road.
Normal practice is coal tar epoxy coating, zinc chromate primer, or some type of epoxy paint system. I think the construction of aluminum tanks at YF is relativley new, they have always made their tanks out of FRP, so I'd be very curious as to their thinking on this.
Again, it's hard to tell from the pictures, but if I were you I'd be asking about it.

BINGO!
I was about to make the same comment and read all the posts first- you are absolutely CORRECT.
"TOP TIER"?
Gimme a break. For what that boat's gonna cost- foaming in unprotected fuel tanks is unacceptable. I'd be a little less concerned about "fit and finish" and more about the important issues like this.
I'd demand they rip the tanks out and do it "right". Or, have fun cutting out the decks and replacing those tanks in ten years.

Thanks darbikrash for your comments, tobnpr, no need to call someone's baby ugly unless your just looking to be inflamatory. Thanks for your constructive criticism none the less.
Nice SeaRay in your signature, I had the 37 express back when they had the 14' beam.

Please don't misunderstand- I wasn't trying to be inflammatory in the least. Granted, my tone may have been harsh, but I was upset over what is, IMO, a REALLY big deal for a guy (you) that's spending a small fortune with the anticipation of getting the very best money can buy. I've never been aboard a YF, and don't have a dog in this fight. You're spending the coin- and you have every right to get the quality you're paying for.
Epoxy-coating an aluminum fuel tank- that's going to be foamed in place and inaccessible, is not "optional". It should be SOP for a boat of this quality. The foam will eventually separate from areas on the tank, allowing air to enter and condensation/moisture to form and become trapped against the tank. It WILL eventually corrode the tank, it may be ten years, it may be a little more, maybe a little less, but it will happen.
There's obviously going to be a large inspection plate over the main center tank, as well as smaller ones over the others- and as you know these things can tend to leak as well. The tanks need to be protected from trapped moisture by the epoxy coating.
You really need to push this with YF- it's really not fitting for a boat of this caliber.
Sorry if I came across as a d***- I wasn't trying to pee in your cornflakes-I just hate to see people get ripped-off, and that's what I think is happening in this installation. For a very small amount of money, those tanks- and there looks to be six of them- will last twice as long.
Congrats on the new boat- she's gonna be a beauty . And thanks as well for the compliment on my SR.
Just another FYI, Fountain used a different quality filler hose than the hose going back to the Racors. The filler hoses weren't designed to have fuel stay in the hose, and deteriorated fairly quickly. It was one of the first things I had to do to my boat when I got her was to replace those hoses. The way those filler hoses are laying they will stay wet, I'd look into that too. You have to remember they've got a thousand items to put on the boat, and they often rely on manufacturers to give the right advice...and sometimes that doesn't happen.
She's a beauty, wish I could afford to run her, much less own her.

lol..as if he'll own this boat in 10 years.
I wouldn't care about the tank foam, either. If I could afford this boat, what aging might do to it in 10 years wouldn't even be on the radar.
Thank you aain for your comments tobnpr, I will be making a call and checking into it Monday. I will also ask about the filler hoses fooltain. I plan on naming her, "The Office". This is a laim attempt to have at least a little truthfulness for when the wife calls and asks me where I am again.... "I'm at The Office hun..... really."
Let us know what they say about the foamed in tanks, I am curious my self. Im not sure its something id worry about my self cause those tanks are sealed in there pretty good in their own compartment. Also now days some of the foams on the markets are very good and absorb no water.
. And thanks as well for the compliment on my SR.
