If you get a 35hp it should push it without to much of a problem. I think you would be safe with a 40/28 Evinrude/Johnson, it would have all the power you would want for that boat. My 16' 42"Blazer SS is rated for 25hp and it has handled my 40/28 just fine. They're a dime a dozen and there bullet proof and got enough torque to haul a good size load. If you could find a 1995-2001 3cylinder 25-35hp it would be a decent motor for your boat but there about like finding a needle in a hay stack. They have more power then a normal 25hp but they don't have as much as the 40hp. Nice medium for your boat. Keep in mind that you'll want a short shaft motor so you'll only need a 22" transom to run it with the jet. An OMC is a good choice if your wanting to put a jet on it. Mercs don't do as well with a jet, they just don't have the low end torque needed for a jet pump. Yamaha's aren't a bad choice either but I only know of people puting jets on the 40hp and up.
