1988 johnson 25 info

I busted my recoil spring a while back.
My thread should help with the repair if you go that route...

Possibly item 54 in the following:

You'd really have to compare the diagram of the whole carb to what you have though to be sure...
From the pics, it looks close, but I can't say if this carb diagram is exact or not.....

I'm even more curious now, so I'm going to ping a few folks I know to see if I can get more info on finding parts for AEM25B...
Probably won't get any good results, but will check anyway...

I have a 1988 Evinrude 25HP. Model # is E25RCCA and the mixture is 100:1, but I usually go a little heavy and make it more like 75:1.

FYI. OMC later reverted back to the 50:1 spec.

If you use the engine daily, 100:1 is fine, but if it sits more than a couple days between uses, then 50:1 will protect the bearings better.

Yeah, that's why I compromise and go 75:1. The previous owner only ever ran at 100:1, but going that light is a little scary to me.

The engine was perfectly fine with 100:1. If an engine runs smoothly at 100:1, 50:1 or 24:1 won't make it run any smoother. The problem, and it is well cocumented, even though 100:1 was more than enough oil to lubricate the engine, it left minimal residual oil on the bearings. As I said earlier, engine that sat for more than a couple of days were at risk of oxidization of the bearing surfaces. If a person were to fog the engine if it was to be left for longer periods, there wouldn't be a problem. However fogging an engine is more of a pain than mixing the fuel at 50:1
