Product Description

With its 362 cc, 2-cylinder SOHC engine layout, the Wahoo 9.9XS excels at delivering a strong torque curve across its 5,000–6,000 rpm range. The standard SOHC architecture presents a reliable, uncomplicated design that keeps internal friction low. While induction in this model is via carburettor (as per the table in the PDF for Wahoo 9.9 XS) rather than EFI, the engine remains efficient and responsive. Fuel is managed precisely, and performance is consistent across load ranges, a hallmark of Selva’s XS range. 

Selva has constructed the Wahoo 9.9XS around a corrosion-resistant aluminium block, paired with a sealed, pump-forced water cooling system to maintain stable operating temperatures. The transmission ratio of 13 : 27 ensures effective translation of torque into propeller thrust with minimal slippage. The design emphasises sturdy internals and lower unit strength to sustain prolonged operation in salt or fresh water. The Long Shaft version gives the propeller better immersion in deeper transoms, improving control and reducing cavitation on larger or heavier craft.

Starting is via manual or optional electric start (depending on configuration in the XS range). The Wahoo 9.9XS is relatively light (≈ 51.7 kg for basic version) making installation, lifting, and transport manageable. Tiller steering with twist-grip throttle gives intuitive control, and trim adjustment options let you fine-tune running attitude, especially useful when trimming for efficiency or shallow water. Its compact profile, low vibration, and smooth mechanical behaviour make it comfortable and practical for frequent use.
