What Octane for 78' 70hp 3cyl. Evinrude?

Just curious as to the octane gas I should be running in my pre-mix? I've been running 93, however, I'm seeing a lot of posts to this site on other horsepower running 87. I'm wondering if that may help with some starting issues I've been having? Any help would greatly be appreciated.

Thanks,

87 octane (fresh), TCW3 oil and Champion plugs. As long as the motor is in good working order you should be good to go. The old motors that have a choke may not start as quick as the ones with primer injection but you shouldn't have any problems.

Good luck!

Thanks for the update Dhadley. Did you happen to see the update to me earlier post on the 1997 Evinrude 150 Ocean Pro's?

Thanks,
