use in brackish, salt, or polluted water to minimize

ing system passages.
The outboard can be flushed on the trailer or at
dockside; running or not running.
IMPORTANT:
The outboard must be located in
a well ventilated area with appropriate ground
drainage during the flushing procedures.
Keep water inlet pressure between 20 to 40 psi
(140 to 275 kPa).
