I have worm gear steering/backward wheel. I'm not in love with it either - I'd rather have a tiller but it is what it is.
I contacted Monitor
about the same question and was told the straight skinny - as long as you are no more than 4 turns lock to lock, dont have too much drag,binding, slop, etc. You should be alright.
I bit the bullet and bought a used Monitor/wheel drum and hooked it up.
I even have alot of slop in my steering and it works great!
I hooked up a simrad
tiller pilot to drive it when no wind or motoring.
Works great! Takes a little playing with and it's not as easy as flipping a switch but it works in all conditions -FOR ME - no guarantees it'll work for you. Depends on the boat - mine's a 48' canoe stearn, DE ketch
, cut away fore foot, long keel
, barn door rudder
, 5 1/2' draft
, 12' beam.
I got lucky - I've got less than $2500 wrapped up in my auto pilot/vane combo and I'm very happy with it.
