Hi, I am looking at a 1994 signature 170. The dealer is asking 4,900 for the boat. The engine and everything looks really clean in addition the dealership is replacing all of the ripped interior and replacing the soft wood. This would be my first boat and I don't want to make a mistake. Any info anyone has about this boat would be great. It has a 3.0 ltr IO is that strong enough to pull tubers and skiers? We are going to test drive it this weekend, any tips on what to look for or check? Thanks
