I saw an ad for a Four Winns 190 Horizon with a 350 chevy motor/volvo outdrive. I'm looking for a first boat and was kind of puzzled by the motor size on this boat. In trying to compare engine, boats are usually listed as 3.0, 4.3, 5.0 etc. How would this 350 compare in those numbers? I was really hoping for a 4.3 but I think that number is equivalent to less than 200hp, right? How would the gas consumption compare to a 4.3? The boat was around 2003 year model. Thanks.
