Which Raymarine autotohelm spares should I carry?

[Mike Bryon]

I’m planning a Madeira, Azores sail next summer using my unknown age Raymarine autopilot system (with ST6002 controller and type 1 linear drive). Would welcome advice as to which parts are most likely to fail and therefore I should prioritise as onboard spares.

Already have a spare rose joint, linear drive and controller but what of the other components reliability?

Trying to avoid the obvious answer of take a complete spare system, so which should I prioritise?

The belt inside the ram is cheap insurance. And carbon brushes for the motor, an old thread was resurrected recently.
I had also the final "connecting ring" (ball joint?) at the end of the ram arm, Dunlop make one at a fraction of Raym price.

Why don't you just tow a spare boat behind you ;-)

Do you have a link to that joint please?

It may be worth your while converting the gears in the type 1 linear drive from plastic to metal - I believe there's a kit from Raymarine to do this. And perhaps carry a spare kit too.

Well worth the cost, friend had gear failure half way across the pond and wound up hand steering.
