Re: Yamaha 6 hp 2 stroke 1986 model , oil mix ratio?
I have a swedish boat magazine from June 1985 that says 100:1 for the
1985 6HP Yamaha.<br />Also 100:1 for 1985 model of Yamaha, Mariner, Evinrude 5HP and Mariner, Johnson and Suzuki 6HP. 50:1 for the Tohatsu 5HP only.<br />I don't want to confuse anyone, but I can understand why your friend said 100:1. Your dealer can confirm the ratio. I belive the fuel tank and engine decal says 100:1 too. <br />I would go for 50:1 anyway. Why risk the powerhead for a few $ of oil a year?<br /><br />Edit: JB said in another
post "Forget the 100:1 mix. OMC rescinded that almost immediately. Use 50:1 with 87 octane regular unleaded." <br />
