This is a new or replacement linear drive for almost any automatic pilot.  This actuator has been installed in at least 4 Peterson Cutters.  It is very strong and reliable, having only 3 moving parts in the pump.  Octopus now has a new product which has a remotely mounted motor and longer hoses.  This allows the noisy pump to be located elsewhere (e.g. the engine room).  Jeff on Beatrix has just had his Octopus Actuator re-configured with 14 foot hoses to do just this.  

The Octopus Linear Actuator is made by Octopus Products 660 Derwent Way, Annacis Island, Delta, BC CANADA, V3M 5P8.  For the P44 models or upgrades speak to Dave Shannon.  Phone: (604) 525-0471.  Fax: (604) 540-3650.  E-mail:
