Can you explain a little bit more about your situation that is causing you to use your tabs while trolling? You mentioned that you were doing it because your boat was all over the place. Are you talking about a zig-zag situation as in you can't track a straight course? Or, is it wanting to pull in one particular direction? Either way, you shouldn't need to use your tabs while trolling except to maybe slow you down? Also, these 2120's tend to ride a little ass heavy, especially if you are running with a full tank of fuel. If you don't need a full tank then you will find running with about a half a tank or so takes some weight off the stern. The other thing that I will tell you is that some of what you are experiencing is that your driving position may be a little forward in the boat than what you have been used to? For example, if you are coming out of a center consol? Your position in the pilot house magnifies this bow high perception somewhat. I know on my first few trips out in mine, I had the same perception. I guess after some time with it you get used to it? The engine trim thing is different for every boat. These 2120's don't need a lot of engine trim as again, they ride a little ass heavy. The best way to find out where the sweet spot for engine trim is by setting throttle at where you are going to cruise then trim up (in small increments) while watching your speed (preferably on gps). You will usually see it increase some up to a point and the if you trim to far it will cause cavitation and or speed will drop back down. Also, when your trim is right you will notice your steering unload some. It's just something you need time with the boat and you will learn where it likes to ride. Depending on what engine you have I would say that you don't need to trim the engine any until you are running somewhere north of about 3600 RPM's as a very broad general rule of thumb. Sea state, currents etc... are why I say broad general rule of thumb.
