That's what I've wrote isn't it?

The shift cut out is on top of the engine

ok so here we are, stolen from iboats forum- shhh dont tell'em. in my simple mind if the engine doesnt cut out you dont have a problem, so in my original post why does it not do anything-- its cos is fine-- Brilliant, if only other things were like that,
------------------------------------------
If you study the intermediate shift plate and the linkage. The function it performs is for the upper shift cable to move the lower (both directions) and allow one to move independently of the other. When independent movements occur, the shift cutout switch will sense this and cause the ignition to be cutoff, ignition is restored when the cables synchronize.

So how does this work? The gear design allows shifting into gear quite easily, hence engaging gears is usually not a problem and the 2 cable movements stay synchronized during the engagement cycle, the switch is never actuated. If you have a sticky lower cable, the upper cable movement will result in an out of sync situation if the lower cable does not move. The switch will be actuated and kills the engine.

Cool we all learn something here :) I have a spare control, but I'm thinking mine is not the same as the ones described here.

That might be why then, I'm talking about Mercruiser inboard controls, I've never worked on big outboards only up to 35hp.
