What about the 25" Motor ?

[cadeco]

That's another question: Why it happens?

I guess that installing a bracket is something like " Do whatever you want!" and latter find out how to deal w/ it.

Yes as i said before i have seen a couple of posts from guys saying that they had to raise the motor a lot and in some of those posts even going to the last bolt, they feel that it should go up even more. That's why i asked the question: 20" shafts are ( in comparison) cheaper then 25" and so, why not?
