Owner Experience Review
Owners and testers consistently frame the Grand Mariner 250 SLEC TritoonfromHARRISas a pontoon party boat and relaxed day‑cruiser. The SLEC layout’s port entertainment center (with fridge, Corian counter and storage) supports hosting, while wide lounges and a large convertible aft sunpad make beach days and sandbar gatherings easy. Multiple entry gates and generous deck space help families move around safely, with a deep swim ladder for frequent dips.
On the water, the tritoon platform with a center 686 mm tube and lifting strakes delivers a soft, well‑balanced ride that stays composed through chop and feels “wharf‑like” stable. It’s easy to drive in inshore conditions, and with a 300 hp outboard, test numbers have shown about 41 knots at the top end; owners running smaller engines report meaningfully lower speeds. Casual tubing is fine with modest power, but for skiing or more aggressive towing, buyers typically look to 250–300 hp.
Long‑term, owners emphasize basic care and covered storage to keep the premium upholstery looking fresh. Reported ownership issues include intermittent electrical gremlins (wiring, lighting, horn, or audio), and isolated pontoon tube leaks or weld repairs that were handled under warranty but could sideline the boat for weeks. Routine outboard items like props and impellers come up, and some modern rigs note occasional sensor or electronic steering sensor replacements. Access to wiring is easier on boats without a fully skinned underside, so it’s worth inspecting that detail during a survey.
Pros and Cons
- The SLEC layout’s entertainment center (fridge, Corian counter, storage) is purpose‑built for hosting on the hook.
- The tritoon hull rides smoothly in chop, tracks predictably, and feels stable and easy to drive.
- Family‑friendly deck plan with multiple entry gates and a large convertible aft sunpad for lounging or overnights.
- Needs a larger outboard (about 250–300 hp) for serious skiing or aggressive towing; smaller engines suit light tubing and cruising.
- Some owners report intermittent electrical and wiring issues affecting lights, horn, or audio.
- Isolated pontoon tube leaks or weld repairs have required dealer warranty work and potential weeks of downtime.
