THe anti ventilation plate should be even with the bottom of the hull for your average installation. To fine tune your rig, move the engine up one hole at a time until it won't hang on at full trim, then go back down one hole. The idea is that most boats will run fine with the plate a little higher. The good side is that you'll be dragging less gearcase throught the water which gives better speed and economy. Make sense?
