I was wrong in my post earlier, I did some checking around and found this: "2005 Suzuki 140 hp - Specks: 185 psi to 242 psi with a 14 psi delta maximum between all cylinders" So I guess they are doing it some how with low octane fuel???
I do know this, I wouldn't mind having one on my 20' sf. They do have a good power to weight ratio. They say the 150's are more dependable with the bigger block but they are so much heavier. The 140 Suzuki is probably one of the best fits weight wise for a seacraft 20' hull if you must go four stroke.

The whole problem with compression is knock caused by pre-ignition, right? If you time the injection of the fuel charge so it coincides with the spark timing, you won't have pre-ignition. Maybe that's how they're doing it. Dave

Hi Mark,
My top speed is 40 MPH, and at cruise (about 25 MPH) I get close to 5 MPG. Of course this is with a light load. Once I start dragging the kids around, you can throw those numbers out the window  Lloyd
