Kicker shaft length question

[bigeasy1]

I meant the antiventilation plate on the kicker not the outdrive. So i have it almost flush with the bottom of the hull.I actually think i could have dropped it a bit deeper.
I typically troll from 2to 5 Mph with the kicker.
If it gets rough i will troll with the outdrive but I have to throw out a drift bag off each side to slow me down and keep and keep the RPMS and oil pressure up on the sterndrive engine(350 mercruiser).
I can tip the kicker all the way out of the water, when we are running back to port or waypoint. There have been a few times when either engine will get some air in the props but it's rare. It usually happens when its nasty and as i get older (I'm 73) it just becomes a pia to stay out and fish in those crappy conditions. that's when im heading back to port for a beer.
