That indicates that the mechanism is in some way 'grippy' as opposed to smoothly increasing friction with adjustment.
The greasing of the cables I've checked all OK......
I wasn't referring to the cables. The friction mechanism is likely to be nylon and the ones I'm familiar with are either nylon washers squeezed to increase the friction or some form of screw with a nylon pad which presses harder on the moving mechanism as the screw is tightened. If the nylon is dry, it seems to take more effort to get it to move than it takes to keep it moving. Consequently, you have to apply more pressure than you would like to get it moving but your control is then lost in the rush and you over move the throttle lever. If the nylon is greased it does reduce the friction overall but it can make the whole operation smoother. However, I have also come across the situation with the screw type of adjustment where, because the pressure is so high, the grease appears to squeeze out from the pressure area and there is little improvement.
Given that your one is crap at the moment, it may be worth a try.
My own throttle is the type that uses two nylon washers which are squeezed together by the pressure of a nut and greasing them was very worthwhile.
My previous Suzi was the screw type and was also greased and worked fine. It did occasionally fall back a bit after a hard landing.
I don't know how you operate your throttle lever when going into gear but, if you don't do this already, it might be worthwhile moving it by tapping the lever forward with the palm of your hand rather than gripping it. For fine adjustment when in difficult seas, rest your hand on the side of the housing and use a couple of fingers and thumb front and back of the lever to balance the forces as you make your lever movements. As usual, if you know this, just ignore me.
