better to burn oil instead of burning up a motor …they say 🙂 .

Can someone tell me about my 53 Evinrude 15 on the rods weather or not they had needles or not? I’m thinking they did but not sure. Asking why the inside the cowl, it stated ” for convenience mix 1 qt in a 5 gallon container. Result was 19 qts of gas to 1 qt of oil.
Anyone know? Needles or bushings?
Always run my 78 Evinrude 85 @ 40/1 ratio. Heard the rings are close to the crown of the piston.

When I was a kid, I took a perfectly good-running ’56 Fleetwin, hooked up a tank of 50:1 EVINRUDE oil mix to it, at the recommendation of a professional O/B tech, and went about 1000 feet at WOT, before it threw a rod. Maybe if I had used JOHNSON oil, it would have been okay? I don’t think so.

Don’t feel bad, OMC sure pushed a lot of “hype” when it came to the capabilities of new and improved oils…. I remember this malarkey being pushed on us by the instructors at service school as well…. I’m convinced most of the engineers had never even seen a 56 Fleetwin, much less worked on them or run them… I always felt that engineers should take an OMC engineering history course every year….Just seems like the same mistakes were repeated again and again, even though past failures should have been a good lesson……
I guess half the problem is that none of the folks that new the history were still around to teach the course!
The other half of the problem is that the sales/cost departments ruled the place, so engineering designs were often squashed due to cost or going against that sales department…

thank you Don!
It was that way at TRW building pipe bombs….or air bags. They wanted us to perform service on the robotic assembly lines running & dealing with explosives. Big meeting with all the staff. I made a few negative remarks about reality check & “show me how you change oil at 65 mph & I’ll follow your lead. The passenger air bag had a 2.5” aluminum pipe packed with explosives. Just to be in the same room with sodium azide was toxic. The robots scrapped too many sodium azide pellets so TRW put people in there to use all the scrapped pellets up.
TRW = terrible risky work!!!!

Thanks for the data on my 53 Evinrude 15. Now I know why the cowl said 1 qt of oil to 5 gallons of fuel!
Sorry guys I was wrong!!
