Mercruiser forward to neutral cuts out!

No, it is not. That feature reside in the remote control box and if this was the culprit, the engine wouldn't even attempt to turn because it cuts the power at the key.

I was referring to an installation on the Trojan. Here there was a switch in each shifter on upper and lower helm that immobilised. No low idle facility as shaft drives However does the engine on the Alpha drive still have the low oil pressure cut off as this might need consideration if oil pressure is not maintained during clutch in.

OK im confused now.. So what is this switch for? I have been looking at the engine and having a fiddle and i have come to the conclusion that the gear shift cable needs replacing as its stiff, If you look at the gear plate you can clearly see that if the shift cable (shift plate to drive) was moving freely it would trigger the switch meaning it WILL cut the engine briefly to change gear..

Or am i wrong?
confused!

here are two for starters , worked for me .


Cable Adjustment:

Remove the dash cable from the shift plate.
Adjust the stud in the slot to the bottom of the slot.
Push the drive cable inwards while someone locks the prop.
It is VERY important to make sure the prop is fully locked.
Measure the drive cable so you have a 6" distance between the hole at the end
and the brass barrel. (center to center!)
Adjust the brass barrel so it measures 6" center to center. Don't move it!
I sure hope that prop was locked in forward (the reverse direction).

Place the drive cable onto the shift plate assembly being careful not to move your 6" adjustment!
Now you have the drive in forward AND the shift plate is in forward too!
Adjust the plastic barrel on the dash cable to match the plate studs so the cable will go right on
without moving the shift plate or the drive cable.
Install the nuts and the cotter pins.

You can now do a static shift test.
Place the control in forward. The prop should lock in one direction and ratchet in the other.
Take a notice of the ratchet tension.
Now go into neutral. The prop should turn both ways free and no noise should be heard.

Shift into reverse and feel the ratchet tension. Also make sure you get a good "lock" in the other direction.
IF the reverse is weak in the ratcheting, then adjust the stud in the lever slide on the shift plate.

The final test is how it shifts in the water!

Just go out and have some fun.
IF you need to adjust the shift, ONLY adjust the DASH CABLE BARREL.

Thanks for that info but im 99%sure i need a new shift cable before i can set it up... t seems the switch will only work in water and when shifting into forward, If it stall when shifting in to neutral then its a bad cable

No, you are right about the function and about the cable. Stiff cables are annoying and will most likely prevent the switch from working accurately.

Looks approximately like this
