Water on top of fuel tanks

[major hattitude]

Hi guys been trying to find out why
I keep getting water coming in on
My 1989 65 My
On top of my fuel tanks between
Engine rooms under floors
Clean up with vacuumed and less
Than a minute water is back
Haven’t rained in a couple days
And water tanks have not been
Filled yet so no fresh water on
Boat wondering anybody has any
Ideas were might be coming in
Any input would be greatly appreciated
Thanks for reading John

If you disconnect the outside waterline and shut your water pump off do you still get the leak?

[major hattitude]

Nope no water has been supplied to boat yet
And water keeps accumulating on top
Of fuel tank

So I’ll clear, water pump is also off?

Try closing ALL your thru hulls, sounds like you have a leaking hose that crosses your fuel lines and the water follows fuel limes to tank. A few gallons an hour is a decent leak.
