Will this also reflace the old cork float in a 1959 Evinrude Lark 35 HP?
We can't match up by your application because we can only verify that this float works with certain application beginning in 1968. The only way we could verify is by OEM number. This cross references with OEM number 382363 (0382363).
I made it work in my 1958 35hp Evinrude Lark. Ethanol doesn't seem to bother it.
