Sorry, I mistakenly read the post before your first post and thought you were saying you were smelling fuel. My bad.
I don't know what your boat has but my tank is poly. I didn't replace my tank, I replaced rotted hoses and that fixed my problem. I don't know that I have any foam in contact with my tank, but I doubt it would have any adverse effect on a poly tank.

The fuel fill hose can be looked at via the starboard side round hatch just below the fuel fill. If it's not cracked to hell, I'd pump out whatever is in the tank and add some gas and see. You could do a redneck leak down test by pulling your fuel vent hose (accessible from the same hatch) and blow in it, wait a minute and let go. It should blow back at you. My 2000 210cc has an aluminum tank.

Lmao, never heard of that and wouldn't even know where to start and that would even work. But what I have seen someone do is stick a latex glove into the fill tube then zip tie it, make sure all other ports are 100% sealed, and in 1 port pump 3psi of pressure until the glove expands just before it were to pop, and then leave it over night in a controlled temperature (heat will cause the glove to become smaller) and of the glove is still the same size then there was no leaks. I think the hardest part in miami, fl is making sure the temperature doesn't go up lol The fuel fill hose can be looked at via the starboard side round hatch just below the fuel fill.

I've read somewhere that it's a good idea to make the cut at 45 degrees around the tank, this will give the deck a good surface to sit back on when you reinstall, makes sense to me. This is true. One should do the same if working with Sheetrock so the patch has something to hold onto.

Id throw 20 gallons in there and see what happens. If you have any gas come out the drainplug, pump it back into some 5 gal gas cans

I have a 1998 190cc with a 2019 Suzuki 115 and have a similar issue. I don't smell gas in the bilge but I keep getting water in the fuel. I've had the tank drained of water by tilting the boat and pulling off of the bottom until only gas. We keep checking the fuel/water separator every hour or two and water keeps showing up. Also there is a separator on the motor (very cool) that has a sensor and alarms when it is full of water. The boat has a new sending unit. Where the heck is the water coming from? You would think if a crack in the tank and water getting in, Gas would be getting out into the bilge.

Is the fuel vent mounted on the outside of the hull? If so, is it broken or facing the wrong way? btw: Welcome to the forum

I think Juan is spot on. Check your fuel vent. Just to make sure I understand, you are finding water in the separator, and if you don't check it soon enough, you get the alarm? Are you using ethanol free fuel?

Juan, I apologize, I didn't see your post until now. I was thinking maybe would have received an email or something. Yes, it is on the outside of the boat and I'm not sure it broken or facing the wrong way. I'll check. That would be awesome if that were the issue. This one has been brutal. So, it could cause the tank to take in a good bit of water? Interesting too. I thought it was just me (my son too) but it seems to happen more we think when using in choppy water.

Exactly, I am finding water in the separator and emptying every few hours. Depending on the day, yes if I don't do it enough, the Suzuki separator (I'll call it) fills to the point where the alarm goes off. I empty that one on land because if I attempt it in the water I will lose something.

And oh yea, non-ethanol fuel only. There was a few gallons of ethanol fuel in it last winter and I thought that was the issue. But after pulling the water off of the bottom and many separator empties I'm pretty certain it isn't from that. BTW, this has happened before this year as well but seems to be worse. Also, before the ethanol gas last winter, we were non-ethanol only.

That would be awesome if we don't need to start cutting into it. Hopefully the vent isn't too hard to get to? Can't wait to see if this is it! Thanks guys!

I think you guys are on to something, hopeful anyway. While pumping gas yesterday some water spewed out of the vent on the outside. Probably a 1/4 cup. I can get to the top of the vent hose next to the filler line via an access hole. The vent line led straight down to foam and I assume through the foam to the tank. The vent hose doesn't have an upward bend at the top to stop water from flowing freely down to the tank. What do you guys think. Thanks for the help!

Can you post a picture of the vent fitting on the hull?

I agree. I'd like to see what he has since with the amount of water getting in, I'm guessing it's been replaced it with a clam shell.

I think you guys are right. I don't have a pic, it's in dry stack at the moment. But its round and silver and sticks out of the boat about an inch with two holes at about 4 oclock and 8 oclock. There's no clam shell. inside, it makes almost a 90 degree turn down with the hose attached down into the foam. It appears there's nothing at all to stop the water from getting in.

Yep, that's your problem. 10 minute fix via the access hatch you've already found.

Great! Are you thinking the quick fix is a new vent, loop the line, or both? I also see the clam shells used around. Can't wait to get it fixed and try it out. Thanks for the help!
