How much is a 25 HP 2 stroke mercury worth to you? After doing research i found them priced any where from 1,000- 2800 for 2002 and newer. The book value for a 2004 is 1,400 but i know that because the lack of abundance they usually go worth more than that. So what do you guys think they are worth? Also long shaft vs short shaft, how much does that effect their value? For the record i have already purchased a motor (2004 25 HP) and am just curious as to your guys view on this.
