What fuel type for 1967 motor?

[Tinkerer2]

1967 60 HP V4 Evinrude<br /><br />Unleaded or lead replacement?<br /><br />I've assumed lead replacement given the age of the motor, but maybe there's some reason why not.<br /><br />I'm more familiar with the issues of valve seat recession etc in 4 strokes and I'm not sure how unleaded can affect 2 strokes.

Unleaded, 87 oct. MOT (equals 92 oct. RON) and TWC-3 rated oil is what you need.<br /><br />A 4-stroke would benefit from lead (valves), but not a 2-stroke.<br /><br />Getting higher octane will have effect on nothing but your wallet.<br /><br />TWC-3 oil is desinged for marine use & running conditions and will provide optimal lube under such conditions.
