integral filter is the usual method of doing this. Fuel tanks, particularly if holding diesel, should
be kept full. This avoids the inevitable sludge at the bottom of the tank being stirred up as it
would be if the fuel level was low, and the sea conditions were rough. And for steel tanks, it also
helps to avoid water condensation within the tank, and the consequent risk of breeding the
dreaded diesel bug – though less seems to be heard of it these days.
Some members are advocates of adding a cleaning additive to the fuel, such as Diesel Redex.
This product is claimed to help free sticky piston rings, and at least one member reports positive
results. Some members also prefer to use white road diesel.
Maintenance
All engines require regular and proper maintenance as specified in the relevant owners handbook.
Before the engine is finally 'put to bed 'for the winter, the cooling system should be flushed, first
with fresh water, and then with a strong solution of anti-freeze. The oil, and the oil filter, also
should be changed
before
the boat is laid up, and the oil should be changed again, mid-season ,if
the engine has had considerable use. The primary fuel filter (sometimes called the water
separator) should be changed at the beginning of each season.
