In 1984 Evinrude and Johnson were selling new low HP 10, 15 and 25 HP engines and recommending a 100:1 mixture. A few months later Evinrude and Johnson rescinded the 100:1 recommendation and went back to 50:1 for all small engines. Quote

Big Hands Posted February 2, 2023 Posted February 2, 2023 I had an 87 15 hp Evinrude that had a 100:1 sticker next to the plug for the fuel line. I did a bit of a dive to find out what was up. 'Rumor' has it that the engine will run fine with the 100:1 mix. The reason they backed off of that is because when the motor sits for long periods (think winter for example) the thinner mixture has a tendency to not provide adequate protection from rust and a lot of people simply aren't able to run their outboard often enough to keep the vulnerable parts from rusting when the fuel is mixed at 100:1. I did try it at 100:1 and 75:1 and had no issues, but I eventually decided that running at 50:1 wasn't going to hurt anything and a little extra protection is better than questionable protection and ran at 50:1 from that time forward. Once I undid all of the damage done by the previous owner, it was a fantastic little motor. It would push my little 14' Valco at 23-24 mph according to my GPS. Quote
