The Bladerunner RIB 35 is due to be sold to the highest bidder at a public event on Monday (December 3).
According to BBC News, auctioneers Bonham's in Brooklands, Weybridge said that the vessel had been stripped of its "Olympic paraphernalia", but still possessed a "torchbearer seat" and the four fake rockets used to generate smoke trails en route to the stadium.
The speedboat - built in 2007 by Hampshire-based company ICE Marine - is expected to fetch up to £300,000 ($481,000) and will also come complete with an authentic Olympic Torch.
Prior to his waterborne arrival, Beckham had been rumoured to be lighting the Olympic cauldron during the ceremony. When asked about his involvement in the lead up to the event, the footballer had simply said: "It is some kind of role in the Opening Ceremony which I'm honoured to be involved in.
"I was involved in the start process with this seven years ago and for Seb [Coe] to have kept me involved, I'm very proud of that."
