I have a 1957 Rockholt Utiliy Cruiser 14ft. My outboard is a 1963 40hp Evinrude selectric shift. I made my maiden voyage today! We spent a good halfhour on the water. The problem is that I can't get the boat up on the plane. Max mph is around 10 mph. I have no tachometer or speedometer as of yet, so this is an estimate. I know that my motor is sitting a little low on the transom and the cavitation plate is 3-4 inches below the hull. Is this the reason I can't get the boat up to speed? Any suggestions on how to raise the engine. <br /><br />Thanks Guys,<br />Sal
