Yes it works. Make sure your engine has enough power. I did it with the old stock 30cc engine and it did not have enough power to handle it.
 
Awesome thanx for the info. Do you know if the stern belt drives any good? And are they still available?
 
Thanks! ...found it on eBay just ordered it should be here in a week or so.

You'll need to shim the second and third shafts a little to get the belt to run true.
After that you'll love it.
While you have it apart you may as well put some decent bearings in.
Go to your local bearing shop and get some high speed rubber sealed ones.
 
Sounds good!!..already did the bearings and aluminum gear plate...stupid question,how do you shim it??..im new to this belt drive stuff.
