Been having trouble resolving excessive spray-back from my jet foot. G3 w/ a home built adjustable transom lift. Have lifted the foot as high as I can w/o cavitation becoming a problem, front edge of foot ~1/2" higher than bottom of boat, but still generate too much spray back. Do any of you out there have experience solving this problem with your own boats? have some ideas but would like to see pics. or hear of proven design before buying materials.
