If you have a Raymarine Autohelm drive unit the cause may be a faulty clutch. Whether you have the Raymarine linear drive or the rotary drive, they take a 12 Volt DC clutch. Care has to be taken on a 24 Volt boat to wire this clutch correctly. All of the Raymarine Course computers I have seen have a method of selecting the voltage for the clutch...I know this because I mistakenly selected 24 volts and burned the 12 volt clutch up.

When the clutch fails, the clutch will slip when hot and the heading will move off course until the computer alarms. The fact that yours is infrequently failing, makes me assume it is the clutch. You can replace the clutch in the drive unit or send it to a Raymarine repair depot and have it replaced. I noticed an "exploded view" of a Raymarine Linear drive (Raymarine autopilotdrive.doc)in the files section of this website. I converted the Word file to a PDF: Raymarine autopilotdrive.pdf and added it to the same section at: http://groups.yahoo.com/group/amelyachtowners/files/AutoPilot%20Tech%20Info%20%26%20Maint./ Hopefully Jose or Gary Silver can delete the larger MS Word file. Hope this helps. Bill BeBe, SM2k, #387 Currently Kas, Turkey --- In amelyachtowners@..., "belitbh" <belitbh@...> wrote:
