Sea-Doo Repair
& Service.

Sea-Doo Is the Brand We See Most

Sea-Doo makes up a large portion of the personal watercraft market, and they make up a large portion of what comes through our shop. We work on everything from the budget-friendly Spark to the full 300hp performance machines — RXP-X 300, RXT-X 300, GTX Limited 300 — and everything in between. We have the BRP diagnostic tools to read the BUDS2 fault codes that the standard OBD readers can't touch, which means we're not guessing when the check engine light comes on.

Sea-Doo builds solid machines, but they have specific failure patterns that come up repeatedly, especially on the supercharged Rotax platforms. If you've owned one for a few years, chances are you already know some of these. If you're buying used, it's worth knowing what to watch for.

Common Sea-Doo Problems We Fix

Supercharger failure (Rotax ACE 300) — The supercharger on the 1630cc Rotax ACE engine is the known weak point. The internal clutch pack wears over time, especially if the ski has high hours or the supercharger service was deferred. When the clutch slips, the supercharger spins down and power drops off sharply. When it fails completely, the failure can send debris through the engine. We rebuild and replace Sea-Doo superchargers regularly — it's one of the jobs we know well.

RAVE valve sticking (two-stroke era) — On older Sea-Doos with two-stroke engines, the RAVE (Rotax Advanced Variable Exhaust) valve is a common issue. Carbon buildup locks the valve in one position and kills power across the rev range. It's a maintenance job that gets deferred on a lot of older skis and eventually becomes a repair.

iBR system faults — The intelligent Brake and Reverse system is great when it works. When it throws a fault code, the ski may not start, or reverse won't engage. Usually an actuator or sensor issue. We diagnose it electronically and fix the actual problem, not just clear the code.

Overheating on the 4-TEC platform — The 4-TEC engine (1503cc three-cylinder) runs hot when the cooling circuit has scale buildup or a blockage. We flush and inspect the entire cooling system and address whatever is restricting flow.

Oil consumption and low oil alarm — Some 4-TEC engines consume oil at a higher rate as they accumulate hours, especially if the ski has been run hard. The low oil alarm is a protective measure — take it seriously. We check oil consumption, inspect for leaks, and assess engine condition.

Sea-Doo Performance Tuning

The RXP-X 300 and RXT-X 300 are two of the best platforms to tune in the market. An ECU reflash unlocks power that BRP deliberately left on the table, and a stainless impeller upgrade matched to the Rotax 300 output gives both more top end and better acceleration. We've done enough of these to know what combinations work best and what to avoid. If you want to build a fast Sea-Doo, talk to us about what's realistic on your specific model before you spend money on parts that won't move the needle.
