I have a 2005 2-stroke 90 Yamaha won't go in reverse. Was out Sunday and everything was fine. Stopped to net some bait and when we went to leave the motor wouldn't turn over. Suspected the shifter wasn't quite in neutral.
Checked shifter and it was in neutral but noticed it wouldn't go in reverse.
I mean the shifter will not move to reverse... stops hard like something is broken or preventing it from moving. Shifts into forward with no problems and a spin of the prop turns the flywheel so it shows it can get into forward OK. Prop spins freely in neutral as well.

Strange thing is the motor will not turn over with the key while in neutral. It seems like the neutral switch is telling the ignition it is in gear when mechanically it is not.

Looked at the linkage in the cowling for issues and everything looks fine.

Any ideas would be great before I drop the lower unit.

Thanks

Sure it is the problem in the engine?the first control, Disconnect cables that go to the engine and check the box remote control:)

I disconnected the control cable at the engine and the cable shifts fine. It is definitely in the lower unit. :mad:

Any help please???

But the engine is the 2005?
The warranty? Yamaha has 3 years
Better contact the dealer
Disassemble the lover casing drive requires special tools and a bit of experience!

In any case unless it is warranted, can dismantle the lower shaft and verify the inverter run manual

Dropped the lower unit and it still did not shift.

Found the nuetral switch has a piece of spring steel that acts like a ramp for the lever on the shifter linkage to close the switch was bent up and out of position.

Pulled the switch bent the piece back into what i think is how it is suposed to be and it now shifts fine. :)

Put lower unit back on and now the plastic piece that rides in the guide that the cable attaches to doesn't seem to move all the way back into reverse. :mad:

I does engage the transmission out of the water but it doesn't feel or look right.
