Boat Lift Boss™ Installation Instructions

For Dutton Lainson® Chain Drive Winch (Kit 3005.7269)

1

IMPORTANT INFORMATION 

Before installation, read and understand all instructions and warnings.  

All 120 Volt units MUST have electrical ground fault interrupter protection.

 Warning: 

Hazardous voltage.  Contact may cause electrical shock and injury. Disconnect before servicing.
• Misuse of this product can result in bodily injury, death, or property damage.
•  Do not overload the capacity of the lift or drive system. When lifting, do not let the cradle or pulleys make contact with the 

lift frame. Serious injury or damage could occur.

•  When lowering the lift, go down just far enough so the boat will come off of the lift. Running the system too long in the 

down cycle will wind the cable backwards and lift the boat, which could cause serious injury or damage.

•  To prevent serious personal injuries or death, do not allow children, swimmers or pets on or near the boat or lift while it is 

in operation as they may become caught under the boat and suffer pinch, amputation or other serious injuries.

•  In the event of unintentional or erratic operation permanently, unplug unit from power source to disable the system and 

contact the Extreme Max service department at 651-357-1862. 

120 Volt Models

120-Volt Boat Lift Boss models must only be used on an electrical circuit that has ground fault interrupter protection. The 

interrupter and its supply circuit MUST be installed to all applicable electrical codes. Any necessary electrical work should 

be done by a licensed electrician. Boat Lift Boss should only be connected to power source by a marine-rated, 3-prong 

grounded cord. Cord should be inspected regularly to insure good condition. Improper wiring or lack of a properly installed 

ground fault interrupter poses a high risk of injury or death.

Loop the electrical cord connection as shown to help 
secure connection.

Instructions

•  Read all instructions and warnings prior to installation and use.
• For use by adults over age 18.
• Wait for the motor to come to a complete stop before changing directions.
• Do not lift anything other than your boat.
• Put one of the two keys on a floating key chain and the spare key in a safe place.

Remote Control Models

•  Remote range will vary depending upon land topography 

and ground clutter (trees, buildings, etc.).

•  Do not use remote more than 15 feet (4.5m) from the lift. 

This will prevent accidentally exceeding the travel limits 

of the boat lift. Never operate the remote out of visual 

contact. 

 Caution: 

120 Volt Models

If the unit will be left unattended, disconnect the unit from power source to prevent damage from lightning and electrical 

surges.

12/24 Volt Models

If the unit will be left unattended, disconnect the unit from the power source or move the power switch to the “OFF” 

position to prevent damage.

Remote Control Models

Never attempt to use the key switch and the remote control at the same time. Do not have the key in the control box when 

you plan to use the remote control to prevent property damage.
