Registering and Titling Outboard Motors

Outboard motors, regardless of horsepower (excluding electric trolling motors), are required to have a Certificate of Title and to be registered with the state of Missouri.

• Application for a title and for registration must be made within 60 days of purchase or of entry into the state.
• The registration of a motor is permanent as long as ownership is not changed.
• Owners of registered motors are issued a motor registration decal, which should be displayed on the left side of the outboard motor.
