cutout switch vs throttle - overview ?

[otgdy]

I am trying to understand the throttle - shift - cutout switch relationships. I don't see how it could work which doesn't help much. If this is posted somewhere please let me know where. My confusion comes from the following.
1. With the shifter parked and locked in neutral the carb is in idle and the shift mechanism has the cutout roller in the bottom of the valley. It starts fine. Doesn't the cutout roller interrupt power when it is in the bottom of the valley ?
One test says to ohm the switch and move the roller slightly out of the valley to get continuity.
2. When I push the throttle forward the throttle cable moves and the shift cable moves after about 2-3in of throttle travel.
Now that is a big delay. Rev'ng the engine that high before engaging the outdrive. That doesn't look right. Yes I am using the correct cable hookups on the throttle.
3. With so much throttle travel in the middle third where the engine throttle is the only thing active. (It travels about the same 2-3 inches before engaging reverse also) why do I need the cutout at all. When I go from forward to reverse the forward gear is disengaged then the throttle goes to idle.. then the engine is rev'd up and then the shift to reverse occurs.

Everything is brand new/rebuilt - cables,throttle,outdrive,carb,cutout switch.

BTW: The engine dies when I put it in gear. So I guess understanding this could help.

Throttle action
<forward engaged and throttle < engine only throttle > Reverse engaged and throttle>

1/3 total travel 1/3 total travel 1/3 total travel
This is without pressing the throttle only button

Any help would be appreciated

Thanks

Ayuh,....

Nope,... Only when the lower cable housing pushes it Outa the V...

BTW: The engine dies when I put it in gear. So I guess understanding this could help.

The lower cable is Junk, 'n is dragging causin' yer Issue...

The shift switch shouldn't move, at ALL,... unless the prop is in the water...

I think you are confusing the shift interrupt system with the neutral safety switch.

The neutral safety switch is in the throttle control. It's only job is to prevent you from cranking the engine over with the starter when not in neutral. Just like your car or truck.

The shift interrupt switch is different, and shouldn't be activated at all going into gear. One note. When shifting into gear without the engine running, you need someone to turn the prop or you will likely hit the high spot of the shift dogs and it will activate the shift interrupt switch. Read this thread on the shift interrupt system. http://forums.iboats.com/showthread.php?p=1930449#post1930449

One other minor question, what are we working on here? Engine? Drive? Year?

Hope your wrong about the lower cable since the lower and upper cables are brand new, however I will definitely check it out. Thanks for the heads up.

This is what is probably confusing me since I have been working it out of the water. Thanks for the thread I am going to read this since I am now curious why being in the water makes any difference. I was under the assumption that all we are working with are mechanical linkages and cam operated switch.. well I guess this isn't entirely true.

The neutral safety is working fine. That's in the throttle itself. Can't start the engine unless it is in neutral. I understand this circuit which is pretty simple I guess.
