Fuel Tank Cleaning and Flushing
IMPORTANT: Diesel fuel should not be left in the tank during winter storage, as an accumulation of rust, sludge, and wax
residue will form.
Refer to the boat manufacturer's instructions and clean the fuel tank at specified intervals. Unless specified otherwise, flush and
clean the diesel fuel tank every 1000 hours or five years, whichever occurs first.

Draining the Seawater System

CAUTION
Water can enter the bilge when the drain system is open, damaging the engine or causing the boat to sink. Remove the boat
from the water or close the seacock, disconnect and plug the seawater inlet hose, and ensure the bilge pump is operational
before draining. Do not operate the engine with the drain system open.
IMPORTANT: The engine must be as level as possible to ensure complete draining of the seawater system.
Drain the seawater system before flushing or prior to cold weather (freezing temperature), seasonal storage, or extended
storage.
IMPORTANT: The engine must not be operating during this procedure.
