Shift Switch - 200 Oceanpro

I have searched the threads but aint got no satisfaction.
The engine is sticky getting back to neutral. It has new cables and lever.
I have the book but not much on this switch. It does close circuit when pushed by hand per book test, but not in actual use when shifting.
Idle speed is good.
Can anyone say exactly how it works - when and how it closes? How to adjust?

Sticking in gear and needing some force and panic to get back to neutral takes all the cool out of docking!
 
Sir, the switch momentarilly disables one bank of cylinders (interrupts the spark), to allow easier shifting and less stress on the clutch dog assembly. When you move the control lever into either forward or reverse the arm it is mounted under momentarilly depresses and it interrupts the spark.
As far as adjustment, from your post it sounds like you are also having problems with your controls or problems in the gears. I would suggest trying to adjust you control, shift cable assembly. Hope this helps.
 
Thanks pops68. I tested the switch again and I was wrong. The switch does not close properly ( high resistance- intermittent ) and sometimes remains closed. I disconnected it last season as it gave me intermittent loss of 3 cylinders ,but it makes getting out of ahead very hard , as you approach the dock. It's all coming back to me now.
My next problem is i searched here, BRP GoTo etc and can't find the switch anywhere.
Anyone know where there is a switch - its pretty much unique to the job and would be hard to botch around.??
 
Re: Shift Switch - 200 Oceanpro - mystery deepens

Thanks all for the info. I got a switch last time I visited usa, and put it in.
I still don't understand it. The switch closes when forward is engaged - a small gear lever arm intercepts the top of the switch to do this. It is then closed ALL THE TIME your are in ahead gear. There is no obvious way this simple mechanism could close the switch for a short time, only when coming out of ahead.
The book is totally slack on this aspect. No picture - no test for actual switch function when shifting.
So I speculated the p/pack does the short off period for 3 cylinders when the switch opens ( back from ahead to neutral.) in the software.
But that theory is no good either because when that switch is closed I believe you only get 3 cylinders full time.
I am up in the yard right now
Any more details out there? I am an electrical engineer - I can handle the truth.
 
When the shift cwitch is closed, you are correct in stating that it shorts out three cylinders on your engine.... the starboard bank.

However in normal operation, that switch is engaged only when shifting out of gear, and this switch engagement period is so short that the momentarily loss of ignition to those three cylinders is hardly noticable..... it's only a blip type thing which allows the shifter dog to disengage from the gear.

Frankly I've never heard of that switch sticking in the closed position since their existence.

If it is actually sticking and causing the loss of ignition on the starboard bank, either the nylon bushings in the shift linkage are salt corroded resulting in stiff linkage/shifting, OR the shift cable is out of adjustment but I've never heard of this causing the switch to stick, OR someone has had the lower unit off and turned the shift rod out of adjustement but I've never heard of this causing the switch to stick either but these are areas worth mentioning.

I assume that the shift switch has functioned properly in the past, and if so, either someone has changed something to interfere with it OR the most likely cause is that the engine shift linkage is sticking especially if you installed a new switch and the problem continues to exist.
 
Thanks Joe. Have you ever watched the switch action while operating the shift lever? (cable removed),
As the shift lever reaches the ahead position , mine will close the switch. and continue to hold it closed as long as the shift lever is ahead.
,It is held close by the gear lever arm as long as the shift is into ahead. But it is not stuck - if you return to neutral ,the switch will open.
There is no picture or explanation in the book & am wondering if something is missing or not assembled right on mine, In Antigua this is always possible.
As far as I know it has never worked since I owned th boat.
I've stared at it until blue in the face and can't see how a momentary action can take place with the mechanism I see.
 
Yep, for that switch to be held closed, either something is missing or assembled wrong. If the year of that 200 is listed above, I keep overlooking it..... what year is it? Hopefully someone here will have a detailed picture of the switch that will be of help to you.
 
Joe I think I see it. On the Bombadier parts diagram there is a thing called 'pin' which seems fit into the plastic switch button. I don't have one. There must be something to this pin because it costs $31.
Will have to order from USA,
Thanks for steering me in the right direction.
 
Yes, that pin has slots so that it rides sideways in the upper portion of the shift lever. Without it, the switch won't function properly that's for sure. I retired around 1991 and my books only go up to 1992, but I looked in the 1992 parts to refresh my memory as I doubted that the shift interrupt switch had changed any..... strange that pin is missing.

Look closely in the engine pan, perhaps it was dropped unseen and is laying there somewhere.
