FRESH WATER COOLING SYSTEM
The standard cooling system for Supra boats is an open
circulation cooling system with intake water. This is preferred
for lakes and reservoirs with low salt content. If the engine is
occasionally operated in salt water, the cooling system should
be flushed with fresh water periodically and always before
storage. If your boat is regularly operated in salt water, it
should be equipped with the optional salt water package.
SALT WATER COOLING SYSTEM
The optional cooling system for use on salt water is a closed
system with a solution of 50% antifreeze and 50% fresh water.
The coolant is left in the closed system and replaced once a
year.
Cooling Systems
Normal use of your Supra causes metal to metal movement
at some parts in the boat. Driver seat track should be
lubricated with a water resistant chassis lubricant such as
silicon grease.
Lubricate rudder grease fitting located below the engine, once
annually.
