How far above the keel should the cav plate be? Is there any type of rule or guideline on this ?

Way to much. You will lose water pressure most likely and cavitate

Well ........... it depends!

What is written above is generally correct and the article Jacque quotes basically covers what I am about to add for completeness.

My cav plate is running about 4" above the keel when the Jack plate is at its lowest - but my motor is on a 6" setback and I am running a semi-surfacing prop.

Yes, that makes sense. That article is a starting point. From there, you take in account what can be done with a setback bracket or jack plate, shallow water lower units, special props etc.

i bought a setback plate. I don't like how it looks so I'm sending it back. I'm chopping her down a little in the morning. I will let you know how it goes... Thanks for all the input! That's the great thing about Bateau. You aren't buying a product. You are buying into a community!
