Page 8: Wheels With Wooden Spokes
Wheels with Wooden Spokes Proceed in the same general fashion as for metal-spoked wheels. If preferred the spokes can be padded to prevent crushing the wood or damaging the varnish under J-bolts. Clear vinyl tubing cut to length and slipped over J-bolt hooks works well. If you prefer not to use J-bolts, you may screw the pulley directly to the wheel using self-tapping or wood screws (Use pan-head screws with washers, not flat-head screws):... -

Page 22: Electrical Connection
Connect motor box power line to a good 12-volt power source with 12ga cable. Even though current draw is low, the CPT will compensate for voltage drop from small wires by increasing current draw. Be sure to use a good quality 10-amp circuit breaker, or attach the 10-amp inline fuse that is supplied. A 10-amp circuit breaker is recommended to avoid a slight 0.04 mA draw when the unit is off. -
Page 23: Setting The Magnetic Reference
The cable exits the bottom side of the box. If the control box does not face the bow or stern of the boat, the autopilot heading will be affected by the boat pitching and heeling. © 2018 CPT AUTOPILOT INC. VERSION 21... -
Page 24: Mounting The Control Box
MOUNTING THE CONTROL BOX The control box MUST NOT be mounted too close to anything magnetic that will influence it, and the location should be checked with a handheld compass before placing an order. See “How to check for magnetic interference” below. Only use included 316 stainless fasteners for mounting the control box, other stainless alloys and fasteners can have a magnetic field. -
Page 25: Testing The Control Box Before Final Mounting
If the magnetic field is too strong the autopilot will not be able to keep the boat on heading. The CPT is able to steer on some steel boats but not all. The electronic sensor in the control box is more sensitive to magnetic fields than the older CPT models that used an optical compass. -
Page 26: Troubleshooting
HOW TO CHECK FOR MAGNETIC INTERFERENCE The CPT heading sensor is built into the control box so the control box mounting area must be free from magnetic influences. The helm area of most boats will be free of magnetic fields, but this should be checked. Use a hand-held compass, preferably a needle-bearing hiking compass, to check for magnetic fields near your pedestal. - Page 27 Steel boats should do a careful magnetic survey, and have a mounting location at least 6 ft from the nearest steel. If a suitable location is not available for the control box, use of the CPT is not recommended. © 2018 CPT AUTOPILOT INC.
