Engine height -Does this look about right?

[sprocker]

Hi All,

We managed to get out for a good blast on Sunday, and took the opportunity to take some photos of my engine height.

This is on the plane, trimmed out at around 18 knots, 4200RPM.

I would very much appreciate your thoughts on whether, based on the pics below, the aeration plate is at a good height, or is it a little deep and could maybe benefit from lifting the engine a notch?

I'd imagine Ed will be your man for this one.
Does it not say anything in any of the manuals?

The manual is excellent as far as the engine itself, but nothing in there dealing with ideal setup.

I don't think it's far off, maybe raising one hole at the most.
