Boat runs fine is perfect smooth water but if there is any chop on the water it seems like the motor will cavitate? this is my first blazer boat, is this normal from a big flat bottom or should i be worried? everything i've read says the leading edge of the intake grate should be flush with bottom of boat and it seems like mine is about 1/4-1/2" above the bottom of boat. Current river marine set it up for me and i'm sure they've done hundreds of these boats and know what they are doing so i thought i'd get some other opinions before i give em a call. Any advise?
