2-Piece Turbo Boost Air Silicone Hose Kit for HSR-Benelli Hydrospace S4 Weber MPE750 Engine

Product Definition and Technical Specifications

The REDOX 2-piece turbo boost air silicone hose kit is specifically designed to replace the original rubber hoses in the turbocharger boost system of the HSR-Benelli Hydrospace S4 stand-up jet ski. These high-performance hoses are manufactured from multi-layered VMQ silicone with reinforced 4-ply construction and 5mm wall thickness, guaranteeing exceptional resistance to thermal and mechanical stress.

Technical specifications include temperature resistance from -50°C to +180°C in continuous operation, perfectly suited to the elevated temperatures generated by the turbocharger. The reinforced multi-layer structure maintains its shape under boost pressure, eliminating risks of expansion and parasitic air leaks that affect original rubber hoses over time. The VMQ silicone material retains its flexibility even in sub-zero temperatures and withstands marine atmospheric agents (salt spray, UV radiation, humidity).

The kit includes 2 pre-formed hoses corresponding exactly to the dimensions and shapes of the original hoses, ensuring direct installation without modification. Hose clamps are not supplied with this kit, allowing owners to use their original clamps or choose high-quality clamps according to their preferences.

Applications and Compatibility

This hose kit is compatible with the HSR-Benelli Hydrospace S4, the world's first stand-up jet ski equipped with a turbocharged 4-stroke engine. The Hydrospace S4 was produced from 2005 to 2012 and is distinguished by its Weber MPE750 twin-cylinder engine with 749 cc displacement developing 110 horsepower with factory turbocharger and intercooler.

The Weber MPE750 engine is a water-cooled 4-stroke inline twin-cylinder with open-loop cooling using unleaded petrol with minimum 95 RON octane. The turbocharger boost system operates at nominal pressure subjecting the hoses to significant thermal and mechanical stresses. REDOX hoses are dimensioned to withstand these intensive operating conditions typical of racing jet skis.

The Hydrospace S4 is characterized by a weight of 170 to 177 kg, compact dimensions (length 2.29 m, width 0.74 m, height 0.70 m) and single-person capacity. This iconic model revolutionized the stand-up jet ski world through exceptional performance and innovative turbocharged 4-stroke technology for its era.
