Original equipment control unit feels sloppy, worn as I advance throttle switching from forward to reverse, like when going slow to dock it is particularly noticeable. The cables look ok and probably were changed by a previous owner. How difficult is that unit to replace? any tips are welcome. I had it all apart last summer in process of recovering the sides vinyl on the boat. It was a pain to figure out how to get it seated correctly again so that I could start the engine!
Looking at a Uflex B183. My OD has no electrical tilt/trim so I just need the basic throttle advance/transmission control unit. Thanks

Cables wear from the inside. The moving wire wears on the housing making the moving wire have to find something to push against in places like bends. Try shifting and advancing the throttle with someone holding the other end from moving then seeing how much play is in the cable.
Just saying

I will try that. The feeling of the control is hard to describe. Advancing the throttle to speed responds normally like you would expect. Its the docking maneuver requiring small bumps forward and or reverse that I notice the play in the control. Hope that makes sense.

Yup, I have eight new cables in the back of my Exploder right now. I bought our 1988 3818 last August and the throttle cables from the lower helm are so worn that I have over an inch of play at the handles. I'm guessing they are original. Getting the engines to near a matching cruise speed is an exercise in bump this one, oops, the other backed off. Shifting the transmissions is mushy and there is confirmed excessive slack in them too.
I had the Uflex controls on my last boat and the only reason I replaced them was because of salt pimples in the chrome plating. At the time I was doing a total repower and the old engines had over 1800 hours on them.

I like that idea.

And yes..... the inner cable (which is actually a flexible yet stiff wire) will wear against it's inner glide sheathe (a rather thin whiteish colored liner) .... especially at points where the cable makes tighter turns.

1985 Capri AQ125a/275 will be equipped with the Morse 33C style cables.
These are typically good cables.

The problem with the single lever controls, is that they first make the gear selection prior to operating the throttle.
Due to the mechanical mechanism that creates the transition, there is an enhirent lag between these two functions.
Even with a new control unit, you will most likely never be able to completely eliminate the lag!

But..... let's back up for a minute.
Take a look at all points of the 33C cable connection.... both at the throttle cable area and at the stern drive shift cable areas.
There is a small cable clamp at the front of the AQ series Intermediate housing. Make sure that this clamp is securing the 33C cable correctly.
Remove the shift mechanism cover from the drive, and take a look at where the shift cable attaches to the gear yoke. Make sure that you have a good solid connection here. Also make sure that the vertical linkage piece is secure.
