Hi, I am having trouble when cruising moving from speeds over tickover back into neutral. Basically when in tickover forwards or reverse I can move the control back into neutral, if I go faster than tickover the lever goes back to tickover but won't then go back into neutral. I can clear the fault by turning off the engine, moving the morse back into neutral then switching back on again. I have had engineers check the cables, the clutch and the gearbox and they say there is no problem. I have a vetus 4.45 engine, with a PRM 150 gearbox. Gearbox and drive plate were fitted new a year ago. Can anyone help?
