The AV plate looks quite low compared to the transom bottom - about 2-3 inches below?

My ETEC 30 was also about 3 inches below the transom bottom on my Zodiac WB465.

How does your MkII Futura run like that?

Also, wouldn't it be better if the bunks on your trailer rested under the main pontoons rather than the speed tubes?

Fixed this issue a while ago. Put the motor up, and changed props. She tops off at 37 mph now. Look closer, there are double bunks on that trailer, Ive had no issues with it at all.
