shouldn't matter what kind of Yamaha it is, the throttle should be the same.

It is not a "type" of engine related problem, it is a installed cable quality and routing issue. The condition of your cables was / is in better shape or routed different than on my old 210 and mine (as I denoted in the other thread) finally bound up so tight they would not move. This though has happened to others and my boat was only 6 months old when it happened from what I can recall... After the cable replacement / upgrade they worked as smooth as glass just like my present 190 system and that is why I made sure the higher quality cables were installed on the new boat "before" I even took it home...

A throttle friction screw adjustment in your present shifter housing though can correct your falling throttle condition in short order
