The invention relates to a method for adjusting the buoyancy of a fishing bobber. The method includes providing a buoyant member and a stem guide configured to receive the buoyant member, mounting the buoyant member to the stem guide and cutting the buoyant member. The buoyant member is made of a material capable of being severed by a cutting device and having first length, a lower end, and an upper end. The stem guide receives the buoyant member and a fishing line with fishing tackle. The buoyant member is cut such that the buoyant member has a second length shorter than the first length. The buoyant member is cut to a second length such that the buoyancy of the buoyant member when cut to a second length is enough to oppose the tendency of the stem guide and fishing tackle to submerse the buoyant member such that a top surface of the cut buoyant member is adjacent to the surface of the water when the stem guide, buoyant member, fishing line and any fishing tackle are placed in the water.
