Sea-Doo Spark Repair

The Sea-Doo Spark is available in both 2-up (two-seater) and 3-up (three-seater) configurations, as well as the trick-focused Spark Trixx variant ².

You can identify your Spark by:

• The Hull: Look for a matte, textured, scratch-resistant plastic hull (Polytec™) ¹ with highly vibrant, molded-in colors rather than painted gel-coat fiberglass.
• The Engine Rating: Located on the engine placard inside the seat cover, displaying either Rotax 900 ACE - 60 (60 HP) or Rotax 900 ACE - 90 (90 HP) ¹.
• Hull Identification Number (HIN): Engraved on a metal plate on the rear-right transom of the watercraft.

• Engine Type: Inline 3-cylinder, naturally aspirated Rotax 900 ACE (900cc) ¹
• Horsepower: 60 HP or 90 HP ¹
• Hull Material: Polytec™ (polypropylene composite) ¹
• Braking/Reverse: Manual Reverse Gate or BRP Intelligent Brake and Reverse (iBR) system (optional/standard on higher trims) ³
• Fuel Capacity: 7.9 US Gal (30 L)
• Storage Capacity: Glove box (0.42 US Gal) with optional front bin kit (7 US Gal)

The Sea-Doo Spark features a unique "split deck" design, where the upper deck is fastened to the lower hull with Torx screws rather than bonded together. To perform most major engine maintenance, the top deck must be completely unscrewed and lifted off.

• Wear Ring Damage: Small rocks and debris drawn into the jet pump can easily score the plastic wear ring, reducing acceleration and top speed. Replacing the wear ring is a routine DIY job.
• PTO Shaft / Oil Seal Leaks: The Power Take-Off (PTO) seal can fail over time, potentially leading to oil in the hull bilge or water entering the engine block ⁴. This seal should be inspected and replaced every 3–4 seasons ⁵.
• Top Deck Screws: The Torx screws securing the upper and lower deck halves must be periodically inspected and kept tightened to a low torque setting (around ~4.5 Nm) to prevent the hull from weeping water or splitting in rough chop ⁶.
• iBR Failures: Models equipped with Intelligent Brake and Reverse can experience gate-jamming from twigs or pebbles, or electrical issues such as blown fuses or wiring harness corrosion ³.
