May not be relevant, but I installed the Teleflex Extreme control cables on my Mercury Outboard ----- I don't have any clue as to how old the original cables were, but MAN, what a difference! Smooth as butter. I use to have to pull the throttle back darn near neutral just to ease up and slow down. Problem was I'd go from WOT to almost neutral. Now, even slight movement at the controls gets a response from the motor.
I don't have any experience with other brands, but I'd be happy as all get out to buy another Teleflex Extreme product if it's needed on another project. I called and ordered straight from Teleflex. Maybe spent $50.
