hey guys, im thinking about buying an 04 four winns h170 with the 3.0 liter 135 hp engine, it comes with a fish finder, and bimimi top. the trailer is in good shape, and it has surge brakes. i should be able to get it for about 7000, this boat hasnt been used very much at all, the guy hasnt even had it out at all this year until the other day he took me out on it. the boat is almost mint, it runs great, needs a tune up, spark plugs, wires, cap and rotor he says he hasnt done it in the 6 years he has owned it, he has done oil changes and he has winterized it every year. First of all do you think this is a good deal? and second of all i have never owned an I/O so what are the normal maintenance things to do other than oil/fluid changes?
