you should be able to free them up yourself, there will be a grease nipple on the pivot, pump some new stuff through it and it should work loose, your twist grip, is it a long shaft with a cog on the end, look under the arm to see if you can spray some freeing agent into the casting

Some throttle twist grips have a friction screw. Perhaps this needs loosening slightly.

As Erin said. Some people like to be able to twist to a throttle setting and release, and maintain that setting. I prefer to have the motor return to idle (or close to it) if the pilot releases the throttle, but that's a personal thing (current boat, with remote controls, doesn't do that.) Throttle friction setting is usually a largish knob near the twist grip.

Other than that, it's usually a cam driving a short length of cable. Should be fairly straightforward to lube it up.

why dont you purchase a grease gun and any make of marine grease (not a runny grease) i am thinking Quicksilver 2-4-C or eqivalent and grease it yourself, buy a service manual that will make your job a lot easier.

In the US court system, an "expert" is defined as "someone who knows more about a subject than the average person". Hardly awe inspiring.
