So since I bought my 2003 21'Palm Beach it has a heavy list to the left. I was told that I could put trim tabs on it, but I really would like to know the reason of WHY?? I have ruled out sloshing gas, unequal loads, and wind.. I am at a loss. The boat runs like a dream other than this. I have heard of maybe the torque of the engine, but I have Yammi 150 V6 2stk. Its a great powerful engine, but come on.. really. So I am leaning toward the trim tab option anyway b/c the boat will ride better. So instead of putting a bandaid on the situation, I would like to understand it. Oh and it only does this when riding flat out on the back bays in the Gulf it is straight up and down.. Thanks for any advise.
