i have a 1999 21' cheetah jet. it has a legend jet with a hydrolic place diverter. i am having problems with the boat porpusing at cruising speeds. i was told i could put cavitation plates on to help. would this be a good idea or should i put hydrolic trim tabs on? would a ride plate help or make it worse? i need some help with this as i am stumped on what to do. i have the money for trim tabs but do i need them. the boat has a closed bow and i talked to cheetah and they said they only made 4 of this style of boat. it has a pretty good size v to the haul. so could anybody give me some advice on what i should do. thanks
