Problem with Morse dual control lever

[maksp]

I have a side-mount morse control lever, the sort which, when in neutral, you move the entire lever outwards from the control unit in order to increase the throttle setting whilst remaining in neutral. The problem is that suddenly the control lever will no longer move outwards. It is not just stiff, it is immovable. Has anyone else encountered this problem and found the reason for it? I cannot see any obvious breakage or fault.

Thanks

Only thing I can think of is are you in nuetral? try waggling the stick about and feel the detent for nuetral.

Controls for Many diesel engines ensure they won't rev over 2500 unless in gear. (prevents over-revving )

maksp, on my boat you need to pull the top of the handle up to enable you to pull the level out before you can rev in neutral (easier done that described.) I had it apart on Saturday trying to figure our how water was getting in through the control, looked like a very simple mechanism but with the potential to seize up. If yours is similar, could you dismantle the controls to enable you to free it/ lube it? (Again on mine, you need to flip off the circular cover on the lever to access a single screw that holds it on.)

Thanks for the suggestions, but none of them seem to fit the problem. There is still a very definite engagement with neutral, and very little wriggle room, although I have tried that. The lever is required to be pulled out before starting the engine, whilst the lever is still in the idle position, so a rev limit does not enter into it. On my control the handle should simply move outwards, there is no release mechanism that might have seized. So, any further ideas still welcomed.

Thanks

My Morse MT-3 lever pulls out at the boss and can then be freely moved to more or less throttle without engaging gear.

It's a simple sliding mechanism with one tube inside another with a spring pulling the central tube back into the body. There's a cross piece, a short solid tubular bar, which drops into a detent in either wall of the outer tube which re-engages the gear change mechanism.

The first thing to do is remove the allen keyed grub screw on the underside of the lever. On mine this is not a metric size but is imperial. It's very close to 5mm but is actually 7/32 I think. Be careful if you have to use a 5mm allen key and use plenty of easing fluid as it is easy to strip.

Once you have removed the lever try and squirt the easing fluid into the rotating tube mechanism as it sounds as if it is corroded into place.

If that doesn't work you will have to remove the control unit and check out the internals. Usually just four cross-head screws.

we had to take ours apart (it was stuck in neutral. just after casting off. ho hum)

aluminium gears, in a seawater environment. they were pretty corroded

managed to save the throttle part of it, but the fwd/reverse cable we had to disconnect. this was 5 years ago, its still disconnected!

it may be saveable, take it to pieces

i got a 2nd hand one in fair nivk, just need to fit it. inside a cockpit locker so i stop kicking it/wrapping mainsheet around it etc. and to keep the salt water off it a bit
