Interesting. I have Centroid senders but they have the flange/gasket mounting setup. Is it common for fuel tanks now to be manuf with that 1-1/2" NPT setup for senders? Never seen that before.

(I have Centroid flanged senders as well. Love 'em..)
Centroid now also has both flatted and hex top sender mounting styles, along with the original flanged.
YF does not put a coating on their aluminum tanks. They said that there are a myriad of concerns with fuel tank placement and installation, and that the coating were not the silver bullett to aluminum corrosion. Several coating were named, I remember coal tar epoxy coating and zinc chromate primer. In all instances it was possible for moisture to get between this barrier and the aluminum as well, in which case the corrosion occurrs. I was told it was at least as important to keep the compartment away from moisture and vice-versa. The foam is closed cell foam, the tanks are in compartments designed specifically for that purpose and nothing else, the inspection ports are silicone sealed. Finally the tank itself is 1/4 inch aluminum significantly thicker than the industry standard. They finished up saying that they had been using aluminum mains for 9 years, and had not had a problem with corrosion on any tank to date.

Thanks for the follow up on the question. I'm pretty sure you can guess my reaction to this excuse, but in the end it does not matter what I or anybody else thinks. What's important is that you're happy with the process and it sounds like you are.
I dont see the need for coating the tanks either. They are in a sealed compartment and will not see moisture on the outside of them. Best thing is keeping the moisture away from the tank to begin with. Bottom line is in my opinion if the outside of the tank is seeing moisture its gonna corrode eventually even with a coating it will find a pin hole somewhere and get behind it.
Good Job on your part Detour not getting drawn into a school yard arguement.
As a YF owner too, I will attest that I have not found any short cuts in YF hardware or processes....I doubt you will either.
24/7 is correct, tanks are in a dry area. I think coatings and foaming in gets more important when you have a tank mounted on the center line and forward boxes drain under the tank to the bilge. in those cases moisture is very prevelant.
Have fun with you new toy. please post back completed pics and performance #'s.
24/7 How does your anchor locker drain? ALso find me a pinhole! I would like to know how moisture could get to the tank considering these samples were removed with a air chisle and the method second from the left does not even have a shiny spot anywhere!
Here is a fighting lady yellow tank going in a Andros! cost $300...
Oh whatever dude, talk about overkill. Give it a rest will you, no need to make a mountain out of an ant hill.
Dont you understand. People always try to see the problems instead of the nice things. Hell if you ask the yellowfin haters they would swear that even though yellowfin is a semi-custom semi-small company they have the biggest propaganda ministry ever. They hired the guy that the Third Reich used. hahaha.
People kill me how they will point out every flaw they see to try and discredit something they are ultimately just jealous of.
That is a beautiful boat and it could have a gas tank made out of old condom wrappers and it would still be one of the best boats on the market.

the devil is in the details....most here are passionate perfectionists and want the best possible product. Here's another appropriate cliche......An ounce of prevention is worth a pound of cure. Sweet boat.

You have it wrong, dude. Why do you assume that because someone points out a potential design flaw in a high-end boat they're "jealous"?
The fact is that aluminum fuel tanks that are foamed in place should have a protective coating to prolong their lifespan. PERIOD. If you can find me an article by an accredited marine surveyor or marine design professional that says otherwise I'll pay you $500... post it up...
It is understandable that entry level, price-point boats may forego this step. For most of us here, it's an inexcuseable shortcut for this particular boat. Even those that own YF's should be able to take off the blinders and admit it just shouldn't be.
We've beat the horse to death. It's still a beautiful boat, and I wish her new owner the best.

This is absolutely phenomenal stuff here. I am a fan of overbuilding, and these tanks make my rev limiter kick in. Great pics, and that is an awesome finish on the fuel tank.

And the guy that has provided these pictures of his work is right down the street from YF.
Moisture???? Did you ever hear of condensation or the marine environment???

I am not knocking YF here I am wondering why a boat company that is building the top of the line CC right now couldnt find a better way? They went old school that basicly decertifies the boat both coast guard and any new boat certifications such as nema or any surveying organization? I have a few Ideas if any one from YF wants to ask of a better way. The tank will last many years the way it is but that doesnt make it right?

Guys, I just wanted to restate that I was told they had 0 failures of their aluminum tanks, each one is in a sealed compartment, with no exposure to the bilge or any channel leading to the bilge. 0 failures and it still needs to be fixed?
