Yamaha VRO

[spareparts]

the yamaha oil injection does not give as much problem as the mercs and Johnrudes, that doesn't mean they are impervious to failure. AS with anything on an engie, make sure its maintained properly, and when it gets old, investigate which parts tend to fail, replace those parts if its cost effective to do so, if not, yank it off and premix. Investigate using amsoil 100 to 1 if fouling is an issue, Yamahas don't have the spark amperage that mercs adn johnrudes do, so I could understand a plug fouling issue if used with to heavy of a premix
