A 100:1 Oil For Yamaha 2-Stroke Outboard Motor?
A readers asks: I’ve got a 2009 Yamaha 20MLHH 2-stroke, 20 horsepower outboard engine. Yamaha recommends a 100:1 mix ratio. I see that AMSOIL HP Marine has a recommended premix ratio of 50:1. I feel that this ratio is too rich for this engine. Is there any way I can get the 100:1 AMSOIL Saber Outboard…
