Purchased V175 wt combo, spec sheet stated with 90 hsp mercury speed of boat to 33 to 38 mph, i elected to by 115 hsp rated at 43 to 45 mph. Have had my boat back to dealer several times because unable achieve anything above 36 mph. have been told that boat would meet specs on a perfect day no more than two people in boat take tackle out, less weight. i have done this and still only runs about36 mph but Tracker says this is still in specs and no further action will be done.
