Stratos 285 magnum is 18'6". Rated for 175. I currently have a 175 HPDI on a manual jackplate and 2 power poles. The 175 weighs 468 lbs. I wanna repower with another Yamaha. The I4 175 comes in at 480lbs and the V6 200 is 529. Would it be a mistake to go with the 200 sho? Would the weight difference be a big issue with the boats handling? TIA.
