Experienced pontoon owners appreciate the Grand Mariner Series for many reasons — sleek styling, thoughtful appointments, cutting-edge technology and proven performance, particularly the option for stern drive power. We guarantee the Grand Mariner SEL 250 won’t disappoint. The SEL 250’s open floorplan offers two spacious bow lounges, amidships lounge opposite the UltraLux high-back reclining helm seat and a luxurious rear-facing lounge with flip-top backrest. Plus, it has an open transom for easy access to the swim deck, with an optional stainless steel railing. If you prefer, you can replace the portside bow lounge with two UltraLux bow seats and a flip up table.
