I have a 81' evinrude outboard on a 16.5' older(70's) v-hull I need to replace the steering in it. My question should I get the rotary or rack and pinion from teleflex? My present system is a rack and pinion I believe because of the tube metal rack housing under the dash. Also should I spend the extra money and go for the no feedback system, I really don't think I need it just wondering what the opinions are.
