Changing Morse control

[adwuk]

I'm thinking about changing the old Morse control on my Nic' 35 as the existing one slips from 1500 down to 1000 rpm when you aren't looking at it. I did read that hanging a hat with beer can to go faster, drink the beer to go slower, was a good solution - but I was looking for something slightly more refined. At the moment I rest my foot on the throttle, but it isn't the most comfortable helming position. I see that there are 2x33C cables to move across to a new control - is it that simple? Anything else that I should consider?
Thanks in advance.

The new Teleflex-Morse control will (should!) come with detailed instructions.

It might be a good time to renew the cables if they are old.

Do you have a tensioner/adjuster screw on the existing control?

You may find your control has an adjustable damper - just needs tightening up rather than replacing the whole unit. Location of the adjusting screw depends on the specific model of control.

Thanks for the replies - I don't think there is a tensioner or friction adjuster. The control is the original 1972 version, and the previous owner had installed a jubilee clip on the throttle cable to add some friction. All this did was cause the cable to snap, and so I can confirm that the throttle cable (at least) is brand new!

I recently installed a new Vetus single lever throttle/gear controller. It came with different harnesses for different types of cables (which was lucky as I didn't realise there were different types) It was simple and straightforward with good instructions. The only mistake I made was the new lever was larger than the previous morse controller, and it fouled on the cockpit seats forward and aft. Not too big an issue as I had the lever machined down to size. The Vetus one seems a reasonable piece of kit, but expensive for what it is, but everything is on a boat.

Thanks - I had better check that as the Vetus SISCO is the one I am looking at as a replacement. Will see if I can take the existing one apart first and find any kind of friction control before replacing.

We replaced Ariam's control last winter for much the same reason. There was a screw which might have been a friction adjuster, but it was seized in the casting. We replaced the cables at the same time, since the existing ones were routed badly (chafing on the fuel tank) and too short to take a better route.

None of it was difficult or complicated.

There used to be cable breaks that would let you put friction on a cable

On a morse cable? Or just an open wire as used on some steering systems?
