I've read through Evinrude's install and predelivery guide and it states on pg 48 "Generally, the anti-ventilation plate of the gear case should align with the bottom of the hull. Conventional V-hulls often perform well with the antiventilation plate approximately 1 in. (25 cm) above the bottom of the hull."

My current setup meets the recommendation above.
See photo on my personal page of AV plate and how it aligns with the bottom of the hull. It is roughly in line to an 1" above depending on tilt/trim.

With that being said, moving the engine mount up 1 or 2 holes would raise the AV plate up another 1" to 1 1/2" above the bottom of the hull.

Is there a general consensus that it would still be OK and engine performance would be good if my current setup is moved up 1 or 2 holes?

Current Prop is a Johnson/Evinrude SST 13 3/8 x 17
