This is a good example of the original jet propelled surf boards ‘SurfJet’, which are extremely rare these days. The board has a 2-stroke engine, which gives a better weight-to-power ratio than similar jet powered surf boards with 4-stroke engines.  The board itself is made out of fibreglass. I believe the engine to be approximately 15 – 20 horse power (HP) based on its size, although I cannot guarantee that as the HP is not specified on the engine anywhere. The dimensions of the board are as follows: Length:                285cm Width:                  76cm The board was working perfectly when last used (approximately 15 years ago) and the engine still starts fine now. There have been some post-factory modifications such as the kill-cord and grip-tape as seen in the photos. The board is generally in good condition however there are some scratches and dings (as shown in photos). The item is sold ‘as is’. If you have any questions, please don’t hesitate to contact me.
