My '81 H16 rudder castings don't have the rake adjustment like the new ones do. And although the weather helm builds big biceps, I'd rather use up my calories in other ways. I've looked in Murray's, and they don't seem to have the new castings. Does anyone have any adjustable ones for sale, or know where I can find them? (I've already redrilled my rudders for max forward rake which helped somewhat)
