Unlike rudder steerable boats, jet boats must have
power applied to the motors in order for the boat to turn.
When making turns, decrease the throttle to reduce the
probability of flipping the boat over. The boat will not
steer when coasting off power.
Never operate your boat in less than 3 inches (7.6 cm)
of water.
CAUTION:
Running your boat in shallow water
increases the chance of debris entering the jet
pump. Verify that the jet pumps are free of debris,
as operating the boat with a blocked jet drive for a
prolonged period will damage the motor and ESC.
If you need to retrieve your boat from the water, use
fishing equipment or another boat.
CAUTION:
Never operate your boat in extreme
temperatures or turbulent water.
CAUTION:
Never attempt to retrieve a downed
boat by swimming to retrieve it.
You can install a servo that allows you to adjust the
boat’s trim via a 3-channel radio.
IMPORTANT:
This option is not available with the
included radio system.
The servo tray fits a 1/18-scale or 1/16-scale servo
(SPMS401). To install a trim servo in the servo tray:
1. Use a 1.5mm hex driver to loosen:
• the set screw holding the steering link push rods
to the servo arm, and
• the set screw holding the trim link push rod to
the servo tray
2. Disconnect the steering servo wire from the
receiver.
3. Use a 2mm hex driver to remove the 4 screws
holding the servo tray to the jet pump.
4. Insert a 1.5mm hex driver into the servo link end
nut and use it as a handle to loosen the link end
nut from the radio tray.
5. Install the servo in the radio tray.
Tip:
Servo hold down screws are not included. We
recommend M3 stainless steel button head screws
with a 2mm hex head.
6. Attach the servo link end nut to the trim servo
control arm.
Tip:
Over tightening the servo link end nut can
cause your servo to burn out prematurely. Test the
servo arm movement by hand to ensure there is no
drag or excessive friction.
7. Use a 2mm hex driver to install the servo tray on
the jet pump using the 4 M3 screws removed in
Step 3.
8. Power ON the ESC, allowing both the steering
servo and the newly installed trim servo to center.
9. Center out the steering nozzle and tighten the set
screw using a 1.5mm hex driver.
10. With the trim servo powered and centered, install
the servo arm perpendicular to the servo.
11. Slide the trim link push rod through the rubber
bellow and into the servo link end nut.
Tip:
Use marine grease on the link for smoother
installation.
12. Set the steering nozzle trim to its desired position.
Using a 1.5mm hex driver, tighten the set screw.
This is now the default trim setting until you make
adjustments with the new trim servo.
13. Using your transmitter, actuate the servo up and
down to find the maximum travel. Ensure the servo
end points are properly set.
NOTICE:
If you do not properly set the servo end points
damage to the servo and/or the jet pump will result.
14. Test the servo trim function in calm water and
adjust the settings accordingly.
