Re: Year and Model of Evinrude
I belive a Lark II can only be a 1960 40hp, but you should check your transom clamp for a model number (on top of the clamp), or the silver disc on the top of the engine block near the back. At the very least, there's a good chance the cover is not original.<br />Evinrude Models 35520-21, 35018-19:<br />Year 1960<br />HP 40<br />WOT RPM 4500<br />Displacement 43.9 cu.in. = 719.4 ccm<br />Cylinders 2<br />Weight 129 - 139 lbs. = 58.5 - 63 Kg<br />Gear ratio 12:21<br />
Picture <br />Spark plugs: Champion J4C (was J4J) gapped at .030" <br />Fuel mix: 24:1 87 octane gas to TCW-3 rated outboard oil. Check out the oil mix faq in the Engine FAQ forum.
