That is interesting too Bob. What did it weigh?

IIRC, 320 pounds, no pan,flywheel,waterpump, manifolds, spark plugs, no
anything.

Bob Darrah.

Thanks Bob.

Sounds high. What did you use for a scale?
That would make it more than 50% greater than a 13B at 190 pounds bare.
The rotor is 9 pounds and the rotor housing is 16 pounds for
a total of 25 pounds for those parts alone. That means the extended
20B e-shaft and 20B rotor housing must weigh about 100 pounds.

A 12A e-shaft is about 16 pounds so give it 18 pounds for the 13B.
Give it another 50% or 9 pounds for a 20B so that would be 27 pounds
That leaves 90 pounds!! for the 20B center housing? The 13B rear housing
which is the heaviest of the three is only 45 pounds.

I think your scale is off by about 50 pounds or so.
