Looking to buy a 2007 Chap Sunesta 274, it has 11 hours on motor. Wife and I really like the boat. We have never owned a boat like this before. Need some info on the boat itself good and bad.. It has a 5.7 liter, 300hp. Will this engine be big enough with a load of people onboard and still travel? also was wondering what top speed this boat would have..Please flood me with info on this boat!!!!!!!
