Had a great first day with the new motor today at the lake. Perfect weather day, sunny and around 70 degrees. The motor is all I was hoping for. Quiet, smooth, powerful, and fuel efficient. It starts just like a car. Turn the key and it’s on, even when cold. I’m definitely not used to that! The prop I’ve got is a Mercury Marine Rev4. 4 blade, 18” pitch. First run numbers are: This was with 2 people and 80 gallons of fuel

3500 RPMs/28 mph/7.5 GPH/3.73 mpg
3620/29/8.3/3.49
3700/30/8.6/3.45
3800/31/9.0/3.44
4000/33/10.1/3.26
4600/40/13.3/3.00
4740/41/13.7/2.99
5940/52.3/24.7/2.11 (WOT)
