[QUOTE="Makaw, post: 498518, member: 25180"] Yes it’s doable, and I recently addressed the same concern. Mine ran 2” low for years, but it ran fine. No “issue” from running at that height, but I wanted to see if I could improve performance by raising it. I built my own jack plate from 2.5” aluminum angle to raise the cavitation plate dead level with the hull. What I found was that raising 2” actually decreased my performance pretty significantly, both in top speed and cornering stability. My jack plate is slotted so it’s fully adjustable. I slowly made incremental adjustments to drop it back down and found that it runs ideally around 1” below the hull. So I essentially raised it 1” from the original position. It didn’t have a massive effect, but it was noticeable for sure. Every boat is slightly different and I’m typically running my boat fairly heavily loaded. A jack plate is a great way to give you the flexibility to find your optimum outboard settings. See some pics below for reference. [/QUOTE]
