motor spray

[kbaudoin]

ok guys ,i just purchased a boat,when i am running trimmed all the way down,my motor throws up a spray on each side, right up against the back of the boat, but when i trim up ,it is normal,the guy had some one put a jack plate on this boat,but the jackplate is all the way up and the motor is bolted on the lowest hole it can go,is the motor still to low? or too high?he said the cavitation plate is about an inch above the bottom point of the transom,which seems about right,,i dont know why he put the jackplate on in the first place,all he had to do was raise the motor one more hole up if he was dragging to much..has anyone came across this before?
