I would suggest you look at a Triumph 150CC.

I have a 170CC (17') for our extra boat on the Island. It is great because you can not damage it - it is made of Roplene (low-density polyethylene) so if you - or an inexperienced relative or one of the kids - bang into the dock, you bounce off. If you have ever seen their ad, the drop it from a helicopter at about 30 feet and it bounces off the tarmac.
Fit and finish isn't great but for a second boat it hits the mark. And, what's best is there are inexpensive.
I have a 4 strke 60hp Merc on mine and I fill the tank twice a year. My wife loves it for running to town and back.
No waxing just some soap and water and a hose.
