Two Speed Motor Retrofits


Upgrade your existing 26, 28 or 29 MARCO Powerblock with a 2 speed motor option installed at MARCO.

Retrofit includes installation of new marinized motor, pinion gear, hydraulic hoses, 2 function control panel and testing of the powerblock.

Installation of one additional hydraulic line is required on the boom to control the shifting option.

All hydraulic motors are now marinized for longer service life. Motor shafts and bodies are coated with a corrosion resistant finish to resist saltwater and prevent shaft seal failure.
