Re: johnson outboard motor
24:1 with 87 octane gas and TC-W3 rated outboard oil. Forget about SAE 30W if it's printed anywhere on the engine, that was good 40 years ago.<br /><br />A little more info:<br />Spark plugs - Champion J6C (replacing the old J6J) gapped at .030"<br />Lower unit lube - OMC/BRP "HiVis" or equivalent 90 weight outboard gearcase lube.<br /><br />Great little engine those 3hps!
