[tsubaki]

Each boat will perform different, mine is mounted a little higher. Only way to really tell is a sea trial.
Mine performs well running wide open (the couple of times I have) even fully extended up, pumps water and dosen't ventilate unless over trimmed.
My major benefit is using in shallow water and when stored on the trailer to be able to tilt the boat in order to drain and have the motor tilted down. Plus when anchored, the foot is completely out the water.
