, Thanks for your latest input guys and sorry to dissapoint tommays its not quite that bad!.<br />Don I have just gone over my motor ect and can confirm evrything is "exactly" as your first pic of the thunderbolt ign set up and they are useing the omc interupter switch in place of the shift cut-out switch in the diagram. They have left the "overstroke" out of the loop and have pulled those wires from the plug.<br />The wires used are...<br />"A"&"B" are not used.<br />"C" is grounded & "D" goes to white/green on distributor.<br /><br />I also have noticed releasing the power of the spring that holds tension on the activating arm that operates the switches it now operates when placing "in gear" also?. PLEASE NOTE..this is without engine running and as don has said before this should only activate when coming "out of gear" with boat in water under normal loads!. To which I will try this weekend at the lake. This leads me to believe I have released a little to much tension from the spring causing it to be far more sensitive but is an easy fix to change back.<br />And Rodbolt, yes I agree if it works ok there is no need for change its just that I dont believe it was working at all when the boat was purchased hence me haveing to turn the idle down to make out of gear changes easier.(my cables are all fine so at this stage are keeping them out of this)<br />Untill now I didnt know much about how it "should have worked" but after all this good info you guys have given, now can put it all into practice and see what a few tools and a day at the lake can produce.<br />So after all this I know what has to be done and what I need to do to try and sort it so at the end of the day if I accomplish nothing mechanicly I have learned allot from your input and will continue to run it as it is and hope for the best

.<br />Also one last thing as Rodbolt said....<br />""for captnemo's benifit.<br />the cut out sometimes will remain ON when in gear and moving the throttle. the overstroke switch opens the circuit to allow normal ign operation.""<br />yes it activates at begining of movement and clicks off in a split second (guess this is good and how it should work!) but half way through throttle it "re-activates" and would hence cut the engine at 1/2 throttle so guess this is where the overstroke comes in to "over-ride" the grounding from the interrupter switch untill comeing off the gas.<br />I will wire in the other switch Don as per your pic and go from there
