Post Operation Maintenance
Daily Care
Serious injury and damage to the watercraft will result if the jet pump
and impeller are cleaned while the engine is running. Always stop
the engine, remove the lanyard lock plate and disconnect the battery
before servicing the jet pump and impeller.
11. Stop the engine and disable all starting mechanisms. Clean the jet
pump and impeller of any weeds and debris that may have
collected during operation. See page 24 for locations.
12. Inspect the area for damage. If damage is found, see your Polaris
dealer for service.
NOTE: Whenever possible, avoid operating the watercraft in weedy
areas. If it's unavoidable, vary the watercraft speed, as weeds tend to
accumulate more rapidly at steady and trolling speeds.
