GENERAL
CAUTION : All hoses and fittings of the
cooling system have calibrated inside di-
ameters to assure proper cooling of the en-
gine. Always replace using appropriate
Bombardier part number.
The Serial Cooling System is utilized on the 717
and 787 engines, which offers an efficient cooling
of the combustion chamber to prevent the possi-
bilities of detonation.
1, Clamp
To cut or secure non-reusable Oetiker clamps of
cooling system hoses, use pliers (P / N 295 000
070).

2. Securing clamp
2, Fitting Spigot
The fitting spigot is used to flush cooling system.
Refer to MAINTENANCE 02-02.
NOTE :
The HX model doesn’t have a fitting
spigot. It has a hose adapter located at the
rear of the watercraft.
3, Elbow Fitting
Water injection used on exhaust system cools the
exhaust gases to obtain maximum performance
from the tuned pipe. The elbow fitting has a cali-
brated inside diameter to optimize water flow in
tuned pipe.
The water injection also helps in reducing noise
level and cools components of the exhaust sys-
tem.
CAUTION : The elbow fittings are calibrat-
ed and can not be interchanged with one
of a different size as severe engine damage
could result.
The elbow fitting can be identified by using the
number stamped onto the fitting or by measuring
its inside diameter. Refer to the following illustra-
tion and chart.
