Suzuki, Yamaha & Mercury Stage 1 calibration for RIBs, day boats and offshore rigs. Mobile to your marina.
Modern four-stroke outboards from Suzuki, Yamaha and Mercury power the vast majority of RIBs, day boats and offshore centre consoles across Poole Harbour and Southampton Water. All three manufacturers tune conservatively from factory for global emissions and durability targets. 24Tuning delivers custom Stage 1 remapping across all three brands — mobile to your marina, slipway or trailer.
Whichever brand sits on your transom, factory ECU maps are calibrated for the widest possible market rather than your specific hull, prop and use case. A Stage 1 remap sharpens throttle mapping and recovers usable acceleration within safe factory tolerances.
Full model-by-model coverage and Stage 1 gains are published on our dedicated brand pages — jump straight to Suzuki, Yamaha or Mercury outboard remapping.

Figures are conservative estimates based on typical Stage 1 marine calibrations. Exact gains depend on engine condition, propeller, load and use case. Torque figures of 0 Nm from source databases are omitted.

Mercury ECU coverage varies more by model year than Suzuki or Yamaha, so we confirm compatibility on enquiry rather than quoting from a generic database. See our Mercury outboard remap page for detail.
