I am about to buy my first boat for the family. We will be using it for days on the lake and some water sports. (the kids are 5 years and 9 months so not too much water sports). I want a sport style boat with enough room to fit 4 adults and 4 small children. Price is an issue, my budget is about 22k plus taxes. I want new, (I do not want somebody else's problems). I have been looking at the following boats, Tahoe Q4, Larson 180 sport, Glastron 185 and the Seaswirl 175. Can anybody give me some opinions on these or any other boat that may fit my needs? If you own one of these what do you think? Do I need to upgrade to the 4.3 litre engine? Thanks in advance.
