Keep in mind it depends who built the boat . Some of these boats are built by amatures and have a dip in the bow that catches water and will make the boat head for the bottom. Others don’t make sure the bottom is straight to the bow . Never cut the holes on the inside of the cockpit to lighten the boat per the plans .If a wave is taken over the bow it fills the side compartments and the boat sinks . I had a 25 hp Evinrude on mine that my Dad and I built and never even got startled at full speed ,Went great and handled great . We added 2 slalom ski skegs amid ships witch made the boat turn well but lost a 1mile per hr . No biggie! The center runner must be made of hard wood to keep the bottom straight. Dad was a nautical engineer on hull design. Boat did 32 mph and safe . Must use tiller cable steering and controls to be safe. Dont be afraid to use a 25 hp I still had freeboard in the stern when boat was at rest. Driver must weigh under 150 lbs with a 3 gal tank in the back. Good luck !!!
