I have a 1996 Marada 21' open bow I/O with 5.0 V8, think around 220 hp - not fuel injected. Think I have a 19 pitch prop. I wasn't fully floored but plenty of power going and my speedo said right around 25 mph and 3400 rpm's. I do like the wake the boat is giving me for wakeboarding and I don't have any issues with get up and go for that which is my main reason for wanting the boat. I have had the boat only to just short of 35 mph and am not sure how much more it has (but I haven't had a good straight away with calm water to test it lately). Just want to know if this seems like a reasonable range for the boat to operate in.
