On my 53 Evinrude (15-1 mix) inside the cowl it stated to mix 1 qt of oil to 5 gallons of fuel. I carried a 5 GI can & exchanged & filled the remote tank. Always had the same mix & never carried a leaky half full oil bottle. Made it easy + had a filter on the GI can for clean fuel. Used a pair of nylons.
Never filled in the boat too. Fire scares me.
