Yamaha AR / SX 19-21ft Jet Boat — 1.8L HO 4-Cylinder PCM Tuning
Transform your Yamaha sport boat's performance with N2 Speed's professional mail-in PCM tuning. The 1.8L HO 4-cylinder engine (1812cc) in your AR or SX series jet boat has significant performance headroom that our expert calibrations unlock safely and reliably.
Compatible Models
- Yamaha AR190 / AR195 — 19ft sport boats
- Yamaha SX190 / SX195 — 19ft sport boats
- Yamaha AR210 / SX210 — 21ft sport boats
- Single and twin-engine configurations supported
What's Included
- Full PCM read and backup of your factory calibration
- Custom fuel map optimization for improved power delivery
- Ignition timing refinement for peak torque and horsepower
- Throttle response enhancement for water sports performance
- Rev limiter and speed adjustment (where applicable)
- Optimized acceleration for faster plane time and hole-shot
- Enhanced towing performance for wakeboarding and tubing
Performance Gains
The 1.8L HO platform responds extremely well to calibration work. Expect 10–18% improvement in acceleration, faster time-to-plane (critical for wake sports), stronger towing pull, improved fuel efficiency at cruise, and more responsive throttle control.
Twin-Engine Note
For twin-engine AR210/SX210 models, each PCM requires individual tuning. Order one service per engine for a matched set of optimized calibrations.
