Carburation and cooling

The suction carburation system does not feed petrol by gravity, so no fuel tap is required. According to the listing, it does not clog, requires no cleaning and prevents fuel loss, drips, stains and petrol odours.

• Fibre filter in the fuel tank and an anti-drip fuel cap.
• No diaphragm or choke control.
• Air cooling, with no water pump, to avoid overheating associated with blockages or breakage of such a pump.

Because it is a four-stroke motor and does not use oil mixed with the petrol, the listing associates its operation with lower fuel consumption and less spark-plug fouling.

Compatibility and lower-unit parts

The GX50 block, including the cylinder and piston, is similar to the HONDA GX50; the listing describes it as durable and reliable.

The listing declares all HONDA GX50 spare parts compatible, including the block, cylinder, starter, plastic parts and silencer, among others.

The carburettor, electronic system, tank and throttle are compatible, but very different from one another.

The lower-unit parts are generic, are used by various brands and can be purchased from marine shops.

Spare parts, maintenance and inherited costs

The store states that any spare part for this motor is available, even when it is not listed on the website.

• The inherited listing gives the lower-unit shaft at €40 and the complete engine block, with cylinder and piston, at €170 as examples.
• The stated maintenance is limited to oil changes, which can be carried out without losing the warranty.
• For comparison, the inherited listing states that a branded motor must be serviced by an official marine technical service and that an annual service for a branded 2,5CV four-stroke motor usually costs between €200 and €300.

Construction and use

The listing states that the motor can get wet with seawater. It is made from stainless materials, aluminium and plastic. Its electronics are basic: 2 wires and a watertight box; these components can get wet.

The specified use for the motor is fresh water. SHERPA is a registered trademark in Spain.
