Hey guys, I have a question for ya. I've been lookin for a motor for my 14 ft. jon boat and have found 2 that friends of mine have. The first is an 1985 Mercury 9.8 hp. for 350.00, no tank and the second is an 1996 Evinrude 15 hp, 500.00, 2 tanks (one new) Both are in good condition and operate well. Water pump works good, forward and reverse gears work good and both start right up, idle and throttle up. Which is the best buy? I would think the Evinrude, but then again I don't know much about them. (Evinrudes) Is there anything I should look for on either. I value your opinions very much, so help me out please before purchasing one.
