I’ve been going through a box of props that I don’t need, nor
never knew what they originally were on, that I want
to get rid of at Tomahawk.
I’ve wrote down all the numbers I could find, noted rotation,
shaft size, # of splines, etc..
I then proceeded to do Internet searches on each. In some
cases I’d find additional information about diameter and pitch,
but rarely "exactly" what they fit.
For one OMC prop I found info that it fit various motors from
a 1968 55 hp, to a 1984 90 hp. Is that even possible?
What’s the best way to ID props as to what they "fit"?
Below is what I came up with so far for an idea of what
I’m up against. I’m not asking anyone to try to ID each prop
for me, just wondering "how" I can do better. The shaft diameters
were measure in the back side of the prop bores, as some of
them had splines on the front side.
Thanks, Buccanneer
