Default Sloppy Rotary Steering

I seem to have a fair bit of slop in my steering. Its a Teleflex single rotary helm about 20 years old. I replaced the cable 2 seasons ago. Pretty sure I'm going to replace it with the NFB 4.2 Helm. How much play is normal for these steering systems? It's on a 21' SeaPro with a new 150hp Mercury. See video!

Time to replace. No need to put up with that. New system cost about $200

...and to be clear, but the entire system, not just the helm.

If you don't have NFB helm now , you will appreciate the upgrade if you don't opt for better hydraulic system. .
But in the meantime, check to see how much of that play may be loose linkage connection between cable end and engine steering arm.

A lot of that type of slop is from trying to force a semi-seized ( previous in this case) cable to move for too long and helm parts get worn or loose. . In some cases one can open the helm and tighten things to help ( with the new smooth-moving cable.).

Play is definitely at helm. No movement at motor. In the video all that movement never caused any movement at motor. Guessing the gears must be gone in the rotary or maybe a bushing? In any case guess I'll slap a new one on.

Last much play should I expect when it's replaced.
