try this. My wife's BD300 had same issue. I emptied the Trans case of its gear oil, 90 weight, and refilled it with 15/40 motor oil. Works like a charm now and easier to shift. Thas all started when she put alot of force on the shift lever and over time snapped the shift cable. My neighbor came over and suggested the motor oil instead of gear oil. Hes a performance boat mechanic and said that's what they do for hard to shift boats. It works.
