Yamaha 75TLRD fuel injected has an idle problem

[Panama Ron]

Hola from Panama - I can start and idle my motor fine when cold but it stalls when going to neutral entering a dock. Also will not idle afer it is warm. I suspect it is the throttler controller. If I start it with the throttle lever up it starts fine. If I have a buddy manually hold the throttle so it stays above 800 rpm I can put it in gear and off I go. What else could it be? How do I adjust the idle? No boat mechanics on my island! Thanks, Ron

Re: Yamaha 75TLRD fuel injected has an idle problem

as your posting from panama this may or may not be a US market motor.
is it an EFI 4 stroke or a 75 2 stroke.
if its the 4 stroke EFI there is no idle adjustment. it either idles like it did new or its broke/way out of adjustment someplace.
when was the last time it ran correctly?
