What octane for 150 4 stroke?

[tidelee10]

I have a 2011 150 4stroke and run non ethanol fuel....I have been using 87 octane without problem...does anyone run 89 or 93 with better performance? I dont mind spending a little extra $$ if it benefits longevity and performance. Thanks in advance for your input and recommendations.

87 is what is recommended, do not put 93, you cant burn it efficiently,, 89 is ok.. again do not run 93 it is a waste of money and you will not like the results..

Stock 150 will see no benefits from higher octane petrol, just wasting your money
