Just recently purchased a 25 hp 4 stroke Yamaha motor and wonder if it is alright to use 89 unleaded octane gas.
need to check your warranty…my yamaha warranty is voided if found anything under 87 is used.

Check min octane rating. Four Strokes don’t see much difference. 2 strokes you can feel the difference in 4 points.
