Have a 1675 Xl ,side console , same motor tops out with one onboard at 35 mph. My guess is a little over 30-32 for top speed . Fast enough for tubing , skiing as well although you might need a 4 bladed prop for that . Technically you should be within 80% of the rated hp to get decent performance. Should run ok with a couple people ,not a speed demon but not a slug either .
