Just picked up one of these in great condition from a local swap shop paper for $140 complete - I'm happy. The previous owner bought a lobster boat with this "installed" on a wheel steering system - I didn't see the installation but it must have been interesting. I have Raymarine ST-40 Wind and Bi-Data on the boat now, so I think this should be a good addition. Having never owned a tillerpilot I have a couple of questions if anyone has first hand experience:1. Maintenance - anything I need to do? The unit seems to work well in my garage, I'm thinking some lubrication of the shaft may be in order.2. Power consumption - I have no on-board charging and rely on two deep cycle marine batteries: how long can I expect to run this thing before I kill one?3. Anyone with experience using this to hold an apparent wind angle in conjunction with a wind instrument - what kind of reliability can I expect? I'm thinking light air will be more challenging maintaining the proper course.4. Any general usage suggestions - I like to singlehand my O'Day 25, and I'm thinking this will make my life significantly easier. My first thought is running the outboard, I can head up and set the pilot to keep me into the wind while raising sails (I do this from the cockpit so the safety police can relax).Really looking forward to getting on the water - winter sucks. As always, thanks to all who respond, I've learned a lot from you guys over the last couple of years.
