Annoying throttle behavior

[camoto]

2014 AR192:

I've read the other threads about "throttle drop" and this doesn't appear to be my problem. When I put the throttle in the 2nd position (TDE, still idling), it often slips back on it's own to the first position. I've increased the tension and it makes the throttle stiffer, but only past the TDE position in forward and reverse, everything in between is still really loose.

Is there another adjustment I need to make to keep the throttle from pulling back out of TDE?

Thanks in advance for any help!

Adjusting the slack on the throttle lever comp maybe:

Thanks for the reply. The first link shows how to adjust the cable which I have done and the adjustment is correct. The 2nd link I have read a few times and I am of the understanding that it addresses a condition where you experience an RPM drop after putting the throttle into a given position which is not the issue I am having.

Let me try to explain it in more detail:
I put the throttle into the 2nd detent with NO increase in RPMs (only utilizing TDE) and often times the throttle lever slips back to the first detent (forward no-TDE). Any other throttle position it works perfectly.

Nothing useful to add, but kickass avatar you got there @camoto !

I see. Do you have the service manual, maybe there is something else that can be adjusted? (Im thinking aloud, don't mean to be annoying!)

Unfortunately I don't. It's strange to me that the friction adjustment only affects forward of TDE.

I have the AR190 one, shoot me a PM with your email if you want I can pdf a copy to you. Not sure it would be helpful...

Thanks! PM sent.

I have the same issue with my 15 AR190. Only when idling in TDE 2nd detent the lever drops back to neutral. This happens when I am utilizing the No Wake mode also.

Sounds like something for the dealer to fix. The dealer won't be able to work on the boat without being able to reproduce the symptom and get approval from Yamaha. My advice is to take video of this happening before you bring it in to the dealer so that they don't waste your time when they take your boat out for a water test and don't find anything wrong. I've used this approach with my dealer and eventually built some trust with them so that they use my video and/or pics as the basis for their warranty claim.
