Gotta have the right prop for your outfit! Your 660 pound boat with 200lbs of people a gas can and life jacket, real quick you will be pushing 1000lbs. My 53 twenty five erude pushes my 14footer about 26/27mph. That Javelin might make it to thirty or so, with the right propeller. Plenty of members looking for one of those fancy Johnsons, if you have the mind to sell it. Sound like fun for sure!
