Good To Know
Q: Does this valve include the solenoid or cable? A: No, this is just the valve assembly. The solenoid and cable must be reused or purchased separately.
Q: Will this fit Ski-Doo 600 HO models? A: No, this is specifically for non-HO models. HO models use a different valve design.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
