Tracker Jon boats

I would like to buy a Tracker Topper 10' Jon boat and on the website it says
that max person weight is 314 lbs and max hp is 3. I do not know that much
about boats so someone who knows about them or has one please let me know if
that is pretty accurate. My main fishing buddy and I go about 200 lbs each
plus our gear, also he has a 9.9 hp engine, not sure what make) that we were
going to use, is that too much? If so, what would be the max I could safely
put on it? Thanks in advance.
