Howdy, Farmor.<br />Welcome to the board.<br /><br />To get the proper 50:1 ratio you would use 20ml of TC-W3 rated outboard oil to one Litre of petrol.<br /><br />The Johnson and Evinrude small twins are among the best outboards ever made. There are hundreds of 40 and 50 year old examples still in regular use.<br /><br />If you can supply us with the Model number from the tag on the mount we can verify the year of manufacture.
Hmmm.<br /><br />Model CD19 is a 1962!! CDL would be a long (20")shaft. You should be using a 24:1 to 32:1 mix for fuel, Farmor!!<br /><br />Change the oil recommendation to 30ml per liter of petrol. <br /><br />Grumps:<br /> <br />You really ought to post your questions on a new thread rather than piggybacking.<br /><br />Your '64 should be able to use 50:1 mix. I believe '64 was the year they changed the spec. on mix.
Hello, Farmor.<br /><br />Yes. I think that the distance from the top of your transom to the anti-ventilation plate is about 20". That is known as a "long" shaft. A "short" shaft would be 15".<br /><br />Ideally, the height of your boat's transom should be about the same as the shaft "length".<br /><br />Your engine should weigh about 60lb.<br /><br />Good luck.
