About this tender
The wallypower50X is the build we ask Wally for when a programme needs genuine outboard performance inside a hull that still reads as a proper wallypower. At 15.4m LOA it sits between the wallytender range and the wallypower58X, and Wally has been deliberate about borrowing from both: the taut deck lines of the power series, combined with the more open cockpit and aft deck architecture that the wallytender buyers know well. The result is a platform that adapts to a day-boat brief or a short coastal passage without looking like a compromise.
The 'X' suffix is Wally's shorthand for outboard optimisation, and the 50X takes that seriously. A notched transom accepts four Mercury outboards rated to 500 hp each in the optional Racing V8 500R configuration, giving a verified top speed of 54 knots and a 280 nm range at cruise. Dial back to the standard four-unit Mercury Verado V10 425 hp package and you still have 48 knots and 320 nm - numbers that cover most Mediterranean itineraries without a fuel stop. Unladen displacement of 13,500 kg keeps the power-to-weight honest.
Below decks, the 50X carries a two-berth cabin and a shower room, so the boat works as a standalone overnight run rather than purely as a chase tender. The modular deck layout adds further flexibility: the source material references both standard and optional deck configurations, which means captains can configure the cockpit around a water-toy deployment brief or a guest-comfort brief without structural changes. Classification is CE-B and F, certified by RINA, and the boat carries twelve persons on board.

Highlights
The four details we'd point out first to a captain who hasn't seen one on the water yet.
The 50X is built around a purpose-engineered transom notch that accepts four Mercury outboards. In the standard Verado V10 425 hp fit that is 1,700 hp combined; with the optional Racing V8 500R package it rises to 2,000 hp. Both configurations keep direct, natural water access at the stern uncompromised.
Wally quotes 54 knots top speed with four Mercury Racing V8 500R outboards and a 280 nm range at cruising speed. The standard Verado fit returns 48 knots and extends range to 320 nm, giving owners a real choice between peak performance and passage efficiency without changing the hull.
A 2,800-litre fuel tank is large for a 15.4m outboard day boat and is the principal reason the 50X can quote 320 nm at cruise on the standard engine fit. It also gives the Racing-package boat meaningful range at moderate throttle settings, keeping the vessel useful across a full day of water-sport operations.
Wally offers both standard and optional deck layouts for the 50X, with separate plan drawings for each. The more open cockpit and aft deck borrowed from the wallytender series means the configuration can be adapted to guest transport, water-toy deployment, or coastal cruising without structural modification.
The wallypower50X is classified CE-B and F by RINA S.p.A., Italy's independent classification society. CE-B covers offshore conditions up to Beaufort 8 and significant wave heights to 4m, providing the certification baseline owners and captains need for Mediterranean and broader coastal deployment.
