Does anyone know which specific size drive gear I need when
installing Raymarine Type II rotary drive.
I'm replacing my original NECO autopilot in my 1987 AMEL
Maramu #231. I have all new Raymarine electronics and instruments and will add
the evolution with the rotary drive.
Problem is the boat is in Mexico
and I'm in Alaska
planning the install.
Hoping someone knows the correct size gear to use.
