Any advice on what oil and what ratio to use in the AD11 57 model Johnson Seahorse?

Re: evinrude and johnson year model needed.

24:1 (one quart TCW-3 rated outboard oil to six gallons 87 octane fuel)

Re: evinrude and johnson year model needed.

DJ,<br />I have an AD11 and the manual specifies 1 qt. SAE 30 outboard motor oil to 1 gal of gas. That would be 16:1. Was the specification revised after manual was printed or does TC-W3 make the difference.

Re: evinrude and johnson year model needed.

If your manual says 16:1 go with that, but 16:1 means 16 parts gas to 1 part oil. therefore 1 qt oil to 4 qts gas would be 4:1. 8 oz of oil to 1 gallon of gas is 16:1 DO NOT use SAE 30 a good outbout 2 stroke oil will work and run better and save your spark plug life<br /><br />Smitty

Hi Herothc<br />The mix ratio for your motor and all OMC outboards of the fifties is 24:1. What you need is a copy of your own owners manual. I don't have one for the AD 7.5hp. I do how ever have one for the QD 10hp. The opperation,adjustments and maintaince are the same. If you would like a copy of this orignal post your e-mail address and I will try and send it to you. This book will explain in detail why the confusion of the 16:1 versus the 24:1 ratio. Also clear up the business of the SAE non-detergent 30wt motor oil. You may as well get it from the sea horses mouth.

IT needs to be bigger. It is too small to read. <br />Thanks, Hero
