Post Subject: Creeping throttle control

When cruisng in our narrowboat, which has an Izuzu 35 engine and controller, the engine "throttle" control lever gradually creeps back, eg, if I set the control at 1400 revs, it gradually slips back, over a minute or two, to the 1200 revs position. Is there any adjustment I can make to the control lever mechanism and or cable linkage system to ensure the lever stays where it is set. The engine has just 280 hours running time, the boat is just about 2 years old.

Some controls have a friction adjustment to stop this and the manual that came with your boat should have the control's paperwork with it. If there is no adjustment on the control then remove and non-return spring from the engine end, but I suspect there will not be one. If not try fitting a light spring between the engine lever and the the block so the new spring is trying to open the throttle. If this is not possible please email me your email address so I can send a simple diagram of something that might help.
