I have dual stations, with flybridge controls connected to the lower helm controls. When I move the shifter at the lower helm, everything moves smooth as silk. But on the flybridge, it is very difficult to shift. Why is that? Is it just because I'm pushing two cable from all the way at the end, instead of from the middle? Would replacing the cables make a difference?

Difficult shifting from flybridge

One of my tower throttles is the same way, even after 2 new sets of cable replacements to the tower & have the Teleflex Xtremes on there now. Same deal right away upon professional installation.
On mine , I believe the contortions of the cable during difficult routing is the likely culprit. That is, even though the bends are within specs for that excellent cable , I suspect it gets over-bent during PIA installation.
The upper controls themselves move effortlessly without cables attached, so it is not a control friction tensioner setting issue on the Morse Twin binnacle controls. Very odd though- as you say , all controls move "smooth as silk" at the lower station, but the tower stbd throttle only is stiff ( enough so small RPM corrections are very difficult for manual synchronizing , so this must be done with the port throttle), even though any movement of upper or lower controls moves BOTH upper & lower cables equally & simultaneously. Sooo- why isn't the friction the same at both upper & lower throttle? Everything is well lubed by me, often, and it has nothing to do with the engine linkage.
Hope the oiling trick works for you , Joe.

Interesting, Sandy -- that is exactly the situation with my shifter. Everything moves together, so the only thing I've been able to figure is that there is some mechanical advantage to being in the middle of the run rather than at the end.
I'll report back after I try oiling. May be a while, though, but hopefully before launch in April.

Bill, I've never done it and was just planning on trying out the trick posted by Old Houseboater:
Cable oiler
Planning to start on the flybridge for the upper cables (and pump down), then do it again from the lower helm down for the lower set of cables.
For the equipment, I'm thinking I can get a tire valve from an old bicycle tire, or maybe from a bike shop. The rest at a hardware store.

I have had great success doing mine from the Bridge down. It takes a while for the oil to get down. Disconnect the cables in the engine room so you can work them more easily while oiling them. Make sure they're not going to bind on anything near them.

Get a valve from a tire store and shave it down with your pocket knife. Bike valve is too small in diameter.

When I built my cable oiler I didn't have a tire valve. I did have quick connect fittings like what is on a pnuematic tool. I just clipped that into my air hose and used the compressors adjustable regulator to adjust the air pressure while oiling the cable.
