My
brother-in-law just bought a boat with a 480 hp Cummins with less than
200 hours on it. Recommendations?



Buy an oil company?

The most important thing you can do for the diesel is to FILL THOSE TANKS
every time you're going to put it away.....leave them FULL and they won't
get water in them. There's no water in the fuel, that's nonsense. There's
water in the AIR breathing in and out of a tank with airspace above the
fuel....

Sun comes up...tank breathes out
Sun goes down...tank breathes in all that wet air that rains on the cold
walls all night....

Sun goes down....tank breathes in all that wet air that rains on the cold
walls all night....water droplets slide down wall under fuel to form
water/fuel layer for the algae to grow in.

Algae cannot survive on diesel fuel. They MUST have a water layer under it
to grow. No water, no algae! It's quite simple....

Diesel-fuel-in-a-bottle at $50/gallon isn't the answer. Filling the tank
is!

You'll still need an oil company to feed a 480hp Cummins....(c;
