Tough break for sure, but it does happen. I would highly recommend getting a professional to clean out the tank. Water in Diesel fuel is a very bad thing and engines are expensive to replace. If you have 2 tanks can you run both engines off the clean one and get it to a marina?

If not then I would start by pulling the tank sender, then with a level check the pitch of tank, both for to aft and port to starboard. Water is heavier than fuel oil so it will gravitate to the lowest center of gravity in the tank. get some rigid hose so you can steer the hose to the low spot and pump it out until you get clean fuel. To be safe I would move the hose around to capture as much as possible.

Many tanks also have sumps and for sure water will collect there as well. Remove the fuel withdrawal line from the pickup (not return line) and start pumping until you get clean fuel. I would go the extra step and use the rigid line to get to the low spot of the sump as well.

Make sure your pump is rated for diesel fuel and exercise all cautions with flammable liquids.


Csnt help you with the racor drains, maybe go on their website. Once you figure that out you will want to drain them quite frequently especially after you bounce around a bit.

Add a little biocide to be safe and carry some extra Racors and secondary fuel filters. Do not use any kind of fuel additive that will emulsify water into the fuel (unless you plan on pumping the tank completely dry)

Good luck.
