There is a clutch system inside the helm behind the dash that makes it no-feedback...

i have 1975 v20 and want to stick with the hydraulic set up. any idea here to find the part?

first time i've disagreed with spare. I may have missed it but I feel the trick is to have your motor set up & trim tab adjusted to minimize torque. Hydraulic is sweet, I have them at work (thanks taxpayers!) but my no feedback single cable costs so much less & I can turn my 200 merc offshore with a finger.
