Mercruiser shifting problem

[Donoway80]

When in the water boat does not want come out of forward or reverse with out forcing it it’s a alpha one gen one I tested the interrupter switch it’s got continuity on it any idea what would make it hard shifting new lower shift cable an new bellows which problem was going on before all this was updated thanks for the help

The bushings on the upper shift shaft, it can bind up..

Where is this bushing located flashback

 

[flashback]

It's where your lower shift cable connects in the bell housing.. not saying that is your problem but a possibility.

I'm no good at posting links but many here are.

With the engine running try pushing the lever that makes the switch cause the engine to stumble.

 

[flashback]

Yep your interrupt switch may be disconnected.

Kenny if it was bad would it have continuity between the wires or could be something else with it ?

You’d maybe have continuity if it was making a circuit, as it would do when it’s triggered. But in this case, your ignition would be cut to half the cylinders usually and have no problem coming out of gear. When you press it manually wirh your finger, does the engine cut the ignition and verve on stalling as it should ?
I’d say that you’d likely need to set/calibrate this mechanism, whilst in the water…should that be what’s required. Pretty sure the dynamics around the operation of such a thing, vary in behaviour, between in and out the water conditions.

Im going to start boat tomorrow an see if can hear differences when trigger switch by hand then try figure out if maybe the cause I thank you for the advice

Good idea, if the switch is working as intended then the motor will stall.

 

[QBhoy]

Yeah. If you physically activate it with your finger for long enough…the engine will stall. Even for a fraction of a second…you’ll hear the engine cut ignition to a few cylinders (as intended when coming out of gear and when set up to do so in the water). It won’t operate as intended when on the trailer though.

Right I got you it makes sense but I do not ever remember hearing it change any when in the water could be the problem I hope so guy really got me good on this boat but I’m far enough in now I can’t give up have to much tied up into it now

the alpha 1 outdrive shift cables ... I was the bellows .. then was the wrong shift cable of rev/fwd .. take it out outdrive and inspect it ... the cable shift shaft is in the bellows ...
the fwd drive throttle and take it out of the outdrive ..

Yes I replaced lower shift cable when had outdrive off replacing the bellows figured while I was there might well replace cable also

the new shift cable is the fwd drive and the engine top of it the brass barrel center barrel, and the stud 6 inches ....
also the cable of the tube turned the cable tighten it up , then ccw 4 turns of that tube ... the alpha 1 ...
also the throttle cable is fwd and the prop is the left ....then neutral the spin no noise , and the rev throttle right counter clockwise the prop .
the throttle cable brass barrel is a prop troubleshooting and the brass barrel did two turns cw /ccw of the barrel ...

I triggered switch herd engine die down so where would I go next with the hard to get out of gear if anyone knows

I was the shift cable brass barrel 1/2 of the cw/ccw ... then the throttle handle shifting fwd /neutral and rev ..of the prop ...
the shift outboard cable is the lube of the penetrating oil ..
the switch is a lube and the switch marker ..

Ok tomorrow I will try lubing everything up it’s got a brand new lower shift cable
