It is a lot of money if you do it with mercury parts. If you want electric start and choke, (a solenoid on my 05) plus controls and cables it is about $1000. I did mine for very little, but I had the old gale remote and the tiller motor came with a starter. I also had a machine shop at my disposal. My conversion allowed me to still use the original tiller controls if needed. Be aware that a bad hook up that fails can be deadly! I can dig up some pics if you like.
