Who the Supra SE550 Is Built For
Choose the Supra SE550 if you want a full-size, high-horsepower wake and surf boat with a stable, wide-beam platform. At 24.5 feet long with a 102-inch beam and 575 horsepower on tap, it's built for riders who want serious wake performance without sacrificing room for the crew. If you're still deciding whether the SE550 or a smaller Supra fits your life on Tennessee's lakes, this guide walks through exactly what you need to know.
Power and Platform: The Core Specs
The SE550 is powered by an Indmar Raptor 575 engine producing 575 horsepower — the same powerplant found in Supra's SL550. That engine lives inside a fiberglass reinforced hull that stretches 24.5 feet, with a 102-inch beam that gives the boat its wide, planted stance on the water. An 83-gallon fuel tank means fewer interruptions on a full day at the lake.
The wide beam isn't just about looks. A broader stance contributes to a more stable platform at surf speed, which matters when you're dialing in a wave or managing a full boat of family and friends.
The SE550 in Context: How It Compares to Other Supra Models
Premier Watersports carries several Supra models, so it helps to know where the SE550 sits in the lineup.
Model | Length | Engine | Horsepower | Fuel Capacity |
|---|---|---|---|---|
SE550 (2024, pre-owned) | 24.5 ft | Indmar Raptor 575 | 575 HP | 83 gal |
SL550 (2026, new) | 23.5 ft | Indmar Raptor 575 | 575 HP | 83 gal |
SL450 (2024, pre-owned) | 23.6 ft | Indmar Raptor 450 | 410 HP | — |
SL400 (2024, new) | 23.5 ft | Indmar Raptor 400 | 356 HP | — |
The SE550 is the largest of these options, offering a full foot of extra length over the SL-series boats. Both the SE550 and SL550 share the same engine output — the key differences come down to hull geometry, layout, and intended riding style.
A Pre-Owned SE550 at Our Nashville Location
We currently have a 2024 Supra SE550 in our Nashville inventory. It features a blacked-out hull finish and carries the full 575 HP Indmar Raptor 575 engine. This is a pre-owned boat — ideal for a buyer who wants SE550 performance at a price below a new-model build.
If you're near Old Hickory Lake or anywhere in the greater Nashville corridor, this boat is worth a visit. Our Nashville location is at 1280 South Water Ave — you can reach the team at (615) 575-8021.
What to Ask Before You Buy an SE550
A few questions worth thinking through before you commit:
What's your primary riding discipline? The SE550 is categorized as a wake and surf boat — it's built for riders who want large, sculpted wakes and surf-ready waves, not casual cruising.
How many people are usually on your boat? The 24.5-foot hull and wide beam give you room to spread out; consider your typical crew size.
New or pre-owned? A pre-owned SE550 can put you in a high-horsepower 575 HP platform at a lower entry point. A new build lets you spec exactly what you want.
Which lake are you on? Norris Lake, Old Hickory, and Watts Bar all have different characteristics. The SE550's size and power suit open, expansive water.
Also Worth Considering: The 2026 Supra SL550
If you want all the same engine power as the SE550 but prefer a slightly more compact hull, the new 2026 Supra SL550 at our Knoxville location is worth a look. It's 23.5 feet long, shares the Indmar Raptor 575 engine, and comes with a strong options list — including Dual Stern Thrusters, Electric Power Steering Assist, a Power Folding Tower Bimini, cooling seats at the helm and observer positions, underwater lights, and more.
The SL550 at Knoxville is white and new. Our Knoxville location at 13137 El Camino Lane is open Tuesday through Friday 9:00 AM to 5:00 PM and Saturday 10:00 AM to 2:00 PM — reach the team at (865) 693-9949.
