ENGINE COOLANT
Recommended Engine Coolant
Always use ethylene-glycol antifreeze con-
taining corrosion inhibitors specifically for in-
ternal combustion aluminum engines.
Cooling system must be filled with BRP Pre-
mixed Coolant, P/N 460777, or with a water
and antifreeze solution (50% distilled water,
50% antifreeze).
To prevent antifreeze deterioration, always
use the same brand. Never mix different
brands unless cooling system is completely
flushed and refilled.
Refer to an authorized Rotax Jet Propulsion
dealer.
Engine Coolant Level
With boat on a level surface, coolant should
be between MIN. and MAX. level marks for
each coolant reservoir when each engine is
cold.
IMPORTANT: The boat is considered level
when it is in water. When boat is on a trailer,
block the wheels and raise the bow slightly
with the trailer jack (if so equipped) until the
bumper rail is level.
Add coolant to have the level between marks
as required. Use a funnel to avoid spillage. Do
not overfill.
Properly reinstall and tighten filler cap.
IMPORTANT: A cooling system that fre-
quently requires coolant indicates leaks or en-
gine problems. See an authorized Rotax Jet
Propulsion dealer.
Engine Coolant Replacement
The coolant replacement should be per-
formed by an authorized Rotax Jet Propulsion
dealer.
