2025 Harris Grand Mariner 250

The 2025 Harris Grand Mariner 250 is a 25-foot aluminum pontoon powered by a single 300-horsepower Mercury engine. Built for comfort and entertaining, the boat features plush seating throughout and premium interior finishes designed for relaxation and social gatherings on the water.

The open layout provides ample space for guests, with multiple seating areas and a design that balances lounging zones with sightlines across the water. The 8.5-foot beam gives the pontoon a stable, spacious platform for cruising and anchoring.

This is a new 2025 model, representing current Harris construction standards and available equipment.
