[DG] [DG] Rotary Drive selection

[Hg1]

Derek,

I fully understand the curves. I have had no problem with the power of the unit. My problem was a mechanical failure of the gears. As I said, the old Autohelm units used different gear ratios, and the drives were physically different in overall dimension. The new Raymarine drives are of identical size, and identical gear ratios.

My question is this. Are the gears the same inside a new type 1 and a type 2 unit? I'm afraid that more power will equal more stress on the gears. It's important for me to understand from an engineering perspective since a gear failure can lock up the steering system, but a motor failure will not. My steering did lock up while offshore, but luckily, we were able to free it. In tight quarters it would have been a problem. Is there a designer I can talk with?

Thanks
