Drives all the way in and tabs up. You could put the tabs down to keep the bow down but they are a drag and will slow the time to plane, but the nose wil stay down and you can see better. I never use the tabs to start. Once on plane bump the drives up slowly so you don't blow out and keep going until the steering is neutral, then you can go farther if you want, watch your speed, too much trim will start to slow you down. It takes a whike to get the feel for the best trim, I am still working on it. Do you have mechanical indicators or the electric merc ones? Keep an eye on them and use pinstripe tape of different color to find a few baselines, the trim will change with conditions so these will not work for all but gives you an idea. I am sure you will stop and forget to lower the drives, when you start again you will clearly see why you keep them in, you will go knowhere and spin.
