change leg

[kobib1948]

I have a 2008 Yamaha 20hp short shaft - I would like to know if I can change the short shaft and put on a long shaft
Is it possible
If it is possible is it economical
If possible can it be done by capable individual or is Yamaha service required or special tools
Thanks

Yamaha doesn't offer a extension kit. Not sure if any aftermarket company's offers them or not.
