I am rather new to the forum, so I may be in the wrong area here. I am looking at a Grumman 17 foot, a 1995 model with an 88hp Evin on it (1995) and a Minkota troller, plus a locator. The trailer comes with it. Where do I go in the iboats forum to find the value of this boat? Checking it out before I buy. Thanks for any help.
