I was in the same situation as you a couple of years ago. I purchased a Yamaha Waverunner EX Sport from RiverValley in Red Wing. I see they show them in stock for about $9,100. I think a nice, aluminum trailer will add about another $1,500. I was looking for used, but two years ago, prices for used were not discounted enough vs. new.
The EX Sport is actually rated for 3 people so you can have two on the Waverunner and also tow a tube. The EX Sport is at the low end of the Yamaha models but it’s everything I need in a jet ski. It’s plenty fast enough and weighs only about 543 pounds. Easily handles two riders. My boy and I (about 400 lbs) have both been on it and it pops right up on plane and cruises just fine. And the financing rates are pretty decent if you want to go that route. The Waverunners are four strokes. I’m not sure about the Sea Doos. And Yamahas, at least their outboards, have a great reputation for quality.
