I have the 2020 with the 200 HPDI. I also test drove the 2020 with the 150 Yami 4-stroke. Both engines were green during dealer break-in, but the numbers during initial testing with two people and light fuel were as follows: The 150F had good hole shot and topped out @ about 50 mph turning 5800-5900 rpm. Running about 4500 rpm showed about 35 mph. The 200Z topped out at 58 mph turning 5800 rpm and ran 40 mph at 4200 rpm. Needless to say the hole shot was great. I went with the 200z for the additional umph and only 7 pounds of weight gain. In addition, I was trying to get about 40 mph and in the 4K rpm range. With full fuel and fishing load, the 200z is showing about 40 mph at 4300 rpm and a top speed @ 55 mph @ 5600 rpm. These are numbers on a still green engine with less than 10 hours. The 150F was turning the new 19" pitch Yamaha Reliance prop and the 200z was turning the 21" prop. Hope this helps anyone out there.
