Our boat has been on the hard
for a few months. When it was stored the bow was sitting a bit low, and this allowed water
to pool on the side decks about an inch deep. The water
was sitting on top of the diesel
plate, and a good amount of water ended up leaking into the tank.
We ended up pumping out about 16 gallons of water in the end. Before we started pumping, we used a product that a neighboring boat had, that allowed us to measure the amount of water in the tank. It is a paste that we smeared onto a metal measuring tape and then dipped into the tank via an inspection
plate. The paste turns red where there is water, and showed us that we had the bottom 11" of tank filled with water (see photo). By our tank chart that figured at about 17 gallons. After pumping the tanks
we used the paste again to check for any remaining water (got just a small touch of red on very tip of probe).
The paste had been picked up from a home heating oil
distributor, who uses this to check for water in heating oil tanks
. Works with Diesel
, gasoline and oils.
Stuff is called "Kolor Kut Water Finding Paste".
Anyway, thought others might find this a useful product. Great for checking fuel tank
