I have a 1993 model 15 hp Mercury 2 stroke electric and pull start tiller handle motor I am thinking of selling. I've searched NADA, craigslist and ebay and have not had much luck. NADA has general prices, but I found nothing on craigslist and nothing comparible on ebay. I take this as a good sign, meaning they are sought after items. I'm trying to find a fair asking price to list to it for sale. It runs excellent, no issues. What is a fair asking price for something like this?
