Re: Johnson HD-25 2-1/2 hp parts

[Buccaneer]

I thought I found one more HD-25 Johnson on the rack. Turns out
that it’s a HS-20. According to this chart,
http://www.maxrules.com/models/OMC_mode … 22-69.html
they’re both 2.5 hp, and the years produced over-lap.

HS-20 2.5 1941-49
HD-25 2.5 1946-50

Why would Johnson make two different 2.5 hp outboards?
It looks like the flywheels are different, but I’m not sure
what else.

Prepare to be boarded!
