Maintenance
Drivetrain Lubrication
Always replace the drivetrain parts when they are damaged or show
visible wear or injury and damage may result.
Lubricating the driveshaft is vital to the life of the drivetrain. The
lubricant also acts as a water seal, keeping water from entering the
hull through the stuffing tube.
Replacing the Impeller and Wear Ring
We recommend replacing the impeller and wear ring if you notice
wear or vibration in the drive line.
1. Use the hatch handle to open the battery cover hatch.
2. Remove the top screws on the jet nozzle while holding the nut
using a wrench or pair of hemostats.
3. Lower the reverse gate nozzle to full reverse, and remove the ball
linkage screw.
4. Remove the cooling line from the jet pump nozzle.
5. Remove the remaining screws securing the jet pump nozzle.
TIP: Use a 2mm ball end to remove the screw behind the cooling
inlet port.
6. Loosen the rudder quick link from the servo horn, and loosen the
jet nozzle trim from the quick link.
7. Remove the jet pump nozzle, reverse bucket, and linkages
together as a unit.
8. Loosen the set screw on the motor coupler that leads to the
impeller.
9. Using a pair of needle nose pliers or hemostats, pull the impeller
and shaft from the jet pump.
10. Replace the wear ring by pulling it out toward the back of the boat.
NOTICE: The wear ring and impeller may be sharp. Use gloves to
prevent scrapes and/or cuts.
11. Apply a generous amount of marine grease to the stuffing tube
and impeller shaft to lubricate them.
TIP: We recommend the Dynamite ® grease gun (DYNE4200) and a
piece of fuel tubing or cooling line to make this process easier.
12. Reassemble and reinstall the wear ring and impeller in reverse
order. Pull the bellows through the jet nozzle before securing the
screws to insure a water tight fit. The bellows lip should rest on the
outside of the jet nozzle.
