Taking a 2nd sea trial on a 240 sundancer 260hp 5.0L because the 1st one failed due to the engine not plaining and it only would get up to 3000rpm. MM sent the boat to the mechanic and is now back in the water. My question is with 2 adults and 2 children, what is top speed? The survey stated EST. SPEED: 25/35MPH. Its 2004 134hrs.
