Steering Trim

Use the 

ST. Trim

 knob on the transmitter to adjust the 

steering trim to center the rudder. If the servo arm is 

not close to its desired neutral position after the binding 

process and the rudder cannot be centered using trim, 

please take the following steps:

1.

  Make sure the 

ST. Trim

 knob is set to “0” or neutral.

2.

  Adjust the linkage to the servo so the rudder is 

centered when the steering is at neutral.

Throttle Trim

Adjust the 

TH. Trim

 so the carburetor is completely 

closed when the throttle trigger is at neutral. If throttle 

can not be closed using 

TH. Trim

, please take the 

following steps:

1.

  Make sure 

TH. Trim 

knob is set to “0” or neutral.

2.

  Use needle-nose pliers or ball link pliers (RVO1005) to 

remove or install a link on a control horn.

3.

  Turn the linkage clockwise or counterclockwise until 

the throttle is closed.

4.  Attach the linkage to the control horn after 

adjustment.

NOTICE:

  Throttle trim change may affect engine 

operation. Carburetor settings must be set correctly or 

damage may result.

After Boating

•  Drain water from inside the hull using the drain plug
•  Wipe exhaust residue from the boat
•  Rinse the deck, hull, and metal hardware with fresh 

water, then dry them with a clean towel. After 

cleaning, coat metal hardware with a silicone spray 

lubricant to help prevent corrosion

•  Fully dry the inside and outside of the boat, including 

the water cooling system. Remove the hatch before 

storing your boat

•  Apply a wax coating for automotive finishes to your 

boat to prevent oxidation and to protect against 

damage caused by fuel or other harmful chemicals

•  Repair any damage or wear to the boat
•  Lubricate the flex shaft 
•  Make note of lessons learned from the trimming of 

your boat, including water and wind conditions

NOTICE:  

When you are finished boating, never leave 

the boat in direct sunlight or in a hot, enclosed area such 

as a car. Doing so can damage the boat.
