I don't know
how small your old runabout was, but a 17.5' boat is considered small in itself. I have boated on several lakes in Minnesota, and some of them are not friendly to such small bowriders. If you have a very small family, the 2007 H180 you are considering is just big enough for 4 comfortably. If you are stuck on this entry level, smallest bowrider in FW lineup boat, I would prefer the O/B H180. Even at nearly triple the price of the 2007 H180. If it were me, and I wanted to take full advantage of all the lakes, I would be looking at 20' to 21' boats for more room and better handling/ride in choppy waters.
Good Luck
A bit embarrassing...but I have a 1961 Starcraft 15' with a 40HP on it. We have a cabin up North on a quite small lake and heave had the Starcraft since mid '70s. I am now too old to pull start and put up with the issues of a boat that old. My "planned" usage find any new boat at our cabin on the major weekends...Memorial Day/4th July/Labor day and maybe a couple of weeks in the summer...but would be available for other lakes the rest of the time. We are in Eden Prairie and are semi-retired so could go out to local lakes during the week when not too busy.
The 17.5 thought would be for my transition and learning if a $30K investment if worthwhile. Maybe a 17.5' would not truly be a good "one year" trial? If I end up going nowhere but our cabin the truth is the 17.5' could be a long-term "keeper" as the lake is quite small.
Thanks for your input...I am already a member of the "more horsepower and longer boat" group

Just wondering if this particular boat might provide a transition to learn from...Thanks again...Tom R
I have the H180 with 3L.
If you're only going to be using it on a small lake and mostly just cruising and fishing then it's ok.
