My 230 has an aftermarket fan and thick pulley that could accommodate two belts and extends forward in inch or so before the fan attachment. It appears to be too thick to go back to the stock fan.
Im not sure what other engines might have the same fan pulley as the 230. If you have one, let me know.
Also could trade my 6 blade fan and pullet for yours if anyone is interested in that. Picture is a little blurry but you can see what I currently have and how it appears to be thicker than stock.
