Just finished refurbishing everything in the motor and lower unit and am ready to fire it up. To confirm, what is the recommended fuel mixture, I believe it is 24:1. Also what octane fuel should be used, high test, or regular?

Thanks for the advice.

24:1 is what is recommended. I run regular 87 octane in my outboards, e10 and all... Some folks prefer the ethanol free stuff. Your call...
