have an effective and simple solution to combat internal corrosion
and help extend the life of the engine.
There are a number of good reasons why saltwater boaters will
want to install the QL Neutra-Salt Engine Flushing System:
• It helps prevent corrosion by removing salt deposits, leaving a pro-
tective corrosion inhibitor on all metal surfaces, including: power
steering and oil cooler, engine block, internal exhaust manifold and
risers, thermostat housing, circulating and raw-water pumps.
• It flushes your engine while the boat sits in the water – there is
no need to trailer your boat or hook up to a fresh-water supply in
order to flush and protect your engine.
How Our Flushing System Works:
1. To operate, simply engage the “Flush” switch by pushing and
holding the dash-mounted switch for 45 seconds while running
the engine at idle speed, making sure the engine has an ade-
quate supply of raw water.
2. Once the Flush switch is engaged, the Neutra-Salt concentrate
solution will be injected into the cooling system, leaving a corro-
sion inhibiting coating on all metal surfaces, thereby neutralizing
the salinity of incoming seawater.
3. Before disengaging the Flush switch, you must turn off the engine.
For best results, use the QL Neutra-Salt Engine Flushing System
after every boat outing. Boat owners will typically get 10 to 15
flushes before a refill is needed.
Neutra-Salt Engine flushing concentrate is available through
Volvo Penta dealers, selected independent marine dealers and
retailers worldwide.
