Although not exactly "plug and play," installing the autopilot was not a difficult job. A bit of research and planning were required. Choosing locations for the components and configuring a strong enough mounting arrangement for the drive unit required the most effort. Already having a fluxgate compass and a remote control saved $500 or so. The Octopus drive was a bit less expensive than the proprietary unit, but more importantly provided utility and convenience with its longer travel and remotely mounted pump. Seamless integration with our existing instrument system was a major benefit, as the autopilot can now do about everything a human helmsman can do except keep a lookout.
