I've got the 1850 w/ a 150 Suzuki 4 strk. It's got all the power, speed, hole shot I ever look for. I'm not a speed demon but she gets me moving +/- 45-48 mph which is plenty for me. Can troll w/ it down to 1.6-1.8 mph. Super quiet & never a burp as far as starting or smooth running. Had a Suzuki 140 on previous boat - loved it so much that's why I stuck with brand on this boat. I kind o' laugh at comments re is 150 enough to ski behind. Maybe I'm just an old fart but grew up around boats back in the day when a 75 was huge & 35 - 50 the norm. Pulled skiers just fine with those, mounted on big heavy tubs. I think on the larger motors (150+) the correct prop is as important as H.P. when considering performance.
