Think outside the box a bit and you may be happier in the long run. I/O powered bow riders are really nice, cushy and often quite sleek, but if you intend to keep one a long time the maintenance costs and depreciation can really add up. If I were looking for a Winnipesaukee day-use boat, I'd start with dual-console outboard powered boats and see if there's something in that market segment that you like. They are built more ruggedly than a typical bow rider, and are almost entirely white. White gelcoat and vinyl will stand up better to years of baking in the sun much better than the darker colors you typically see on I/O boats. Modern outboards are thriftier on fuel and MUCH easier to maintain than an I/O. This type of boat will have a much stroner resale than an I/O. A typical dual console will handle rough water better than a typical I/O bowrider and most have self bailing cockpits and positive floatation, a HUGE safety factor on a lake known for chop.
My favorite Dual console in the size range you are looking at is the Grady White Tournament 225: See
