thank you all for your advice i ended up raising the jack plate up about an inch... i went from 5000 rpm's to about 5600 water pressure is still good also gained around 4-5 mph as well running about 65 wide open... thanks again for all your input!! i think the next thing for me to do would be to get a bigger prop and i dont have 300 to bu a used one!

once again thank you all!!
