With Ptt, adjust engine in fully (down) until you';re on the plane, then trim out to find the sweet spot.
With an engine with fixed trim (tinny), use people and gear to your advantage to have a happy medium until its on the plane.
What boat and power are you running? Are you borderline underpowered? Can you put people up the bow for a short time until you get on the plane?
