On the 10 thru 35 or 40 HP 50’s 60’s Johnson Evinrude models, they use the petal reeds on the intake. I found they make them out of brass or a spring steel. I found this because I had an 18 Hp that I could not get to idle properly. I had 1 of each type reed on the plate. Apparently , They flex at different rates. I was either lean or rich. Once I put 2 of the same metal reeds in, It had a perfect idle. My question is , is there any advantage with brass over spring steel reeds or visa versa?

Yeah, I replied to it earlier. I’d like to know what happened to it to!

The Poof Poof gremlins are back at it again.

If that’s true, that is an amazing observation. Since I bring parts motors back from the dead all the time, I will be aware of that. When you got the motor, were the reeds already mismatched or was that something that you had tried yourself? I wonder if the steel one was out of a 25, which uses a whole slew of subtlety different parts than a regular old 18.

Long live American manufacturing!

The motor was that way when I got it. It was driving me crazy, Just could not get it to idle smooth. I don’t know what possessed me to pull the intake plate off, but once I saw the different color reeds, I was on to something.

I’m 77 years of age; ‘ been working (involved) with 2 cycle outboard motors for 6 decades. I’ve yet to see or feel any reeds made of brass.

Conclusion – Brass reeds are as rare as Hen’s Molars ?!

Not sure what they are. They look like brass in color but apparently not. What are they made of?

A magnet will rule out brass in a hurry.

Prepare to be boarded!

The brassy looking reeds are made out of beryllium copper.
