Medusa 028-56 V2 SE ?
 

I am planning on a Medusa MR-028-056-1900V2, a 28x56 size motor for my 580mm Vee boat, but the motor's centering hub is stopping me from this option, 'cause my motor mount has a center hole of 8mm but the motor center hub is 9.53mm in dia.

What's the real use of this hub ring-wall on front endbell casing?

I bought SE versions of the 3670 and 3680 V2s, and found the centering hub has been thankfully removed to have a flat front mounting plate. Will Medusa have a SE version also for its smaller brothers ?:gasp:

Even it it does why not just make a small spacer disk to give you a flush fit?

Or bore out the hole

On my 60 it almost looks like that little mofo is useless, you could probably grind it off...

Thanks guys for your great ideas.
I was thinking of to drill it off with a big (10mm) drill bit, but this requires to remove the rotor while Medusa motors are not rebuildable design and may be damaged when forced open. Dremel/grind it off is another choice but may hurt the shaft by a minor mistake, the metal dust will likely kill the front bearing as well. Looks like to enlarge the hole on the motor mount or adding a spacer are the only ways to go.

Get mike to make you a front cover like he does for the 36mm motors. Good idea as the al medusa uses for the front endbell is a bit soft and the threads are not the greatest either. If you plan to remove the motor frequently you need a front cover.
