Jet Ski Remap Bournemouth

A jet-ski ECU remap is a precision software upgrade that recalibrates your personal watercraft's Engine Control Unit. By optimising fuel delivery, ignition timing, boost pressure and rev limiters, we extract the performance your engine was designed to deliver while operating within safe factory tolerances.

PWC engines are tuned conservatively from factory for reliability, emissions compliance and global homologation. Our in-house engineers reverse these conservative limits using manufacturer documentation and on-water verification.

We remap the three major personal watercraft manufacturers. Open a dedicated brand hub for model lists and Stage 1 estimates:

• Sea-Doo (BRP) — Spark, GTI, GTX, RXP-X, RXT-X and Wake ranges including Rotax ACE engines
• Yamaha WaveRunner — VX, FX, FZ and V1 series including SHO / SVHO platforms
• Kawasaki Jet Ski — STX, Ultra and SX-R ranges including Ultra 310

Browse jet-ski-specific remaps in our jet-ski shop, or contact us with your make, model and year for compatibility confirmation.

The difference is felt immediately on the water. Hole shot improves dramatically, mid-range acceleration strengthens and the ski feels sharper and more responsive at every throttle input.

• Quicker hole shot from standstill
• Stronger mid-range for jumping and racing
• Sharper, more predictable throttle response
• Improved top-end on supercharged models
• Smoother power delivery across the rev range

We designed our jet-ski remap process around marina and mooring convenience, no haul-out required.

1. Diagnostic check: ECU scan for fault codes and sensor status
2. Factory backup: original ECU map stored securely on our server
3. Custom flash: in-house developed map written via professional marine tooling
4. Water test: on-water verification to confirm performance and drivability
5. Handover: written confirmation, warranty registration and aftercare advice

Sea-Doo GTI models are among the most popular recreation PWCs on Poole Harbour and Bournemouth Bay. Factory maps limit acceleration to protect drivetrain components and meet global homologation. Our custom calibration delivers stronger hole shot and sharper throttle response while operating within safe mechanical tolerances.

Sea-Doo RXP supercharged platforms see the most dramatic gains. RXP and RXT owners running performance setups benefit from recalibrated boost and fuelling maps that transform mid-range acceleration for jumping, racing and general recreational use on the South Coast.

Yamaha SVHO (Super High Output) WaveRunners are factory-tuned conservatively despite their high-performance hardware. SVHO recalibration unlocks the acceleration these engines were built for, with improvements to throttle connection and top-end response that owners notice immediately on the water.

Jet-ski remapping should fit around your boating schedule, not the other way around. Our mobile marine engineers attend marinas, slipways and moorings across Poole Harbour, Bournemouth, Hamble, Lymington and Southampton Water. No haul-out or workshop visit is required for most PWC platforms.

We coordinate access with marina staff where needed, work from your berth or trailer setup, and complete ECU flashing on-board using professional marine tooling. Allow approximately two to three hours including diagnostic check, backup, flash and on-water verification. Book ahead during peak summer season when marina berths are busy.

Customers storing skis at Sandbanks, Cobbs Quay, Town Quay Southampton and coastal clubs across Dorset regularly use our on-board service. Contact us with your marina name, berth details and PWC make/model when requesting a quote.

• Full ECU diagnostic health check
• Custom in-house PWC calibration
• Secure backup of your original factory map
• On-board marina or mooring installation
• On-water verification where conditions allow
