anyone have any suggestions as to sources of second hand single lever gear/throttle control? Connects to a Yanmar 1gm 10. Something inside my existing unit has disintegrated and I can get full throttle in forward gear, but barely tick-over speed in reverse - discovered the problem approaching the pontoon with a stiff following breeze and would have had a bad bump but for pontoon neighbours catching the pulpit! I'm sailing an Arden 4 and 4 tonnes at a fair lick would have done both boat and pontoon some damage! I'd prefer not to shell out for a new one at this point in time, so any suggestions welcome!
