Sea-Doo Spark & Spark Trixx – The Ultimate Tuning Guide
The Sea-Doo Spark is BRP's perfect entry-level personal watercraft – compact, lightweight, and agile. What many riders don't realize: the small Rotax 900 ACE engine has significantly more potential locked away from the factory than BRP lets on. With the right tuning, you can boost the output from a stock 60 HP all the way to 120 HP – with a major jump in top speed to match.
Stock Power: 60 HP or 90 HP?
The Sea-Doo Spark comes in two power variants – 60 HP and 90 HP (Spark Trixx). Here’s the interesting part: both models share the exact same Rotax 900 ACE engine. The difference in power is purely in the ECU software configuration. That means both variants can be brought up to the same performance level – no mechanical changes needed for Stage 1.
Stage 1 – ECU Flash: Full Power via Software
With the M-JET FLASHER, you flash your Spark’s ECU directly from your smartphone or tablet – no workshop visit, no disassembly required.
What the flash does:
- Activation of Sport Mode (locked by default on 60 HP models)
- Top Speed Unlock – removes the factory-imposed speed limiter
- Optimization of engine parameters for maximum power output
Result: From 60 HP to 90 HP – approximately 52 mph top speed.
💡 The M-JET FLASHER is compatible with the Sea-Doo Spark (Rotax 900 ACE) – for all model years with 60 HP or 90 HP.
Stage 2 – ECU Flash + Hardware: 120 HP / 57 mph
For those who want to unlock the full potential, combine the ECU flash with two carefully selected hardware upgrades:
Stage 2 Components:
1. M-JET FLASHER
The flash is the foundation of every tuning stage. Without optimized ECU parameters, the hardware can’t reach its full potential.
2. SOLAS Impeller SK-CD-12/14
The SOLAS stainless steel impeller replaces the stock plastic impeller and transfers the added engine power into the water far more efficiently. Polished stainless steel, 3-blade CONCORD design, 140 mm diameter – optimized for the Rotax 900 ACE.
3. SOLAS Stainless Steel Wear Ring
The stainless steel wear ring minimizes the gap between the impeller and pump housing. The result: more thrust, less cavitation, and a higher top speed.
Stage 2 Results:
| Stock | Stage 1 | Stage 2 | |
|---|---|---|---|
| Power | 60 / 90 HP | 90 HP | 120 HP |
| Top Speed | ~46 mph | ~52 mph | 57 mph |
| Components | – | M-JET FLASHER | Flash + Impeller + Wear Ring |

Conclusion
The Sea-Doo Spark is a seriously underestimated tuning platform. With the M-JET FLASHER and the right hardware upgrades, you can extract up to 120 HP and 57 mph from the small Rotax 900 ACE – more than double the stock output on a 60 HP model. The stages are modular: start with Stage 1 (flash only) and upgrade to Stage 2 whenever you’re ready.
