Overstroke switch?

[berke99]

I have an 88 Lund Tyee with a 3.0 ltr. IO, Cobra stern drive. What does an overstroke switch do when it is working properly? I have tested the switch and it is working but I cannot make any adjustements of the cams to make any contact. Thanks for any info.

An overstroke switch will make the engine "flutter" briefly to help get it out of gear. (it actually activates the ESA-or electronic shift assist) They are often called shift interupter switchs. As you pull back on the handle to take it out of gear, resistance from the clutch dog to gear lug is sensed through the transom shift cable, causing a cam to pivot into the overstroke switch. This then "interupts" the ignition briefly, helping the C-dog and gear to disengage.
