Used OEM parts for the Sea-Doo XP series are stocked at Sun Coast Cycle Sports. The XP (eXtreme Performance) was Sea-Doo's historic high-performance personal watercraft line that ran from the early 1990s through 2004, establishing the brand's reputation for speed and aggressive handling. The XP series progressed from two-stroke carbureted engines through direct-injection two-strokes and ultimately to the Rotax 4-TEC four-stroke platform in its final years. The XP was the predecessor to the modern RXP performance line and remains popular with vintage PWC enthusiasts. All parts are inspected, individually cataloged, and ship from our Odessa, Florida facility.
Sea-Doo XP generation and parts compatibility
| Era | Years (approx) | Engine | Key notes |
|---|
| XP (2-stroke carb) | 1993-1999 | Rotax 717/787cc 2-stroke twin | Carbureted two-stroke. Various hull revisions |
| XP Limited / DI | 1998-2003 | Rotax 951cc 2-stroke twin (DI = direct injection) | Larger displacement. DI models have Rotax direct injection for cleaner emissions |
| XP (4-TEC) | 2002-2004 | Rotax 1494cc 4-stroke inline-3, ~155 hp | Final XP generation, first with 4-stroke engine. Replaced by RXP |
The XP spans multiple engine generations with no parts crossover between them. The two-stroke 717cc, 787cc, and 951cc engines are separate platforms from each other and from the 4-TEC four-stroke. Within each engine family, displacement-matched models share internals. The 4-TEC XP's Rotax 1503 engine is the same family used in early GTX, RXT, and RXP models from 2002-2005, so some engine components cross over to those models. Two-stroke XP engines do not share any components with modern four-stroke Sea-Doo models.
XP hulls varied across the production run, with significant redesigns in 1994, 1997, and 2002 (4-TEC). Hull panels from different hull generations are not interchangeable. Within the same hull generation, body panels and deck components are specific to the XP line.
Common Sea-Doo XP failure points and replacement parts
Two-stroke engine rebuild: Two-stroke XP engines require periodic top-end rebuilds as part of their maintenance cycle. Pistons, rings, and gaskets are standard service items. The 951 DI models have additional maintenance requirements for the direct injection system.
Rotary valve seal (2-stroke): The rotary valve oil seal on two-stroke Rotax engines can fail, causing oil leaks and poor running. Replacement is a common service item on higher-mileage two-stroke Sea-Doo craft.
RAVE valve maintenance (787/951): The Rotax Adjustable Variable Exhaust system on 787cc and 951cc engines uses power valves that require periodic cleaning and inspection. Stuck or carbon-fouled RAVE valves cause power loss and rough running.
Wear ring and carbon seal: Standard jet pump wear items that apply to all XP models regardless of engine type. Age-related degradation is a factor on these vintage craft even with low operating hours.
Parts scarcity (vintage models): Early 1990s XP parts are increasingly difficult to source through conventional channels. Two-stroke-specific components (RAVE valves, DI system parts, carburetors) are particularly scarce as the industry has moved entirely to four-stroke powerplants.

Frequently asked questions
Q: Does the XP share parts with modern Sea-Doo models
Two-stroke XP models share no engine components with any modern four-stroke Sea-Doo. The final 4-TEC XP (2002-2004) uses the Rotax 1503 four-stroke engine, which shares some components with early GTX 4-TEC and RXP models from the same era. Jet pump components may cross over across generations if the pump housing dimensions match.
Q: What replaced the Sea-Doo XP
The RXP replaced the XP as Sea-Doo's dedicated performance watercraft starting in 2004. The RXP used the four-stroke Rotax 1503 engine exclusively (dropping the two-stroke option entirely) and introduced the musclecraft hull design that evolved into today's T3 platform. The RXP carried the XP's performance-first philosophy forward with modern four-stroke technology.
Q: Are two-stroke XP parts still available
Availability is limited and declining as the industry has moved entirely to four-stroke engines. Aftermarket suppliers still produce rebuild kits (pistons, gaskets, seals) for popular Rotax two-stroke engines. Model-specific hull and body components are scarce and used OEM parts from donor craft are often the only option.
