JET BOARD, here is the movie: /jetboard/jb.mov

ITEM DESCRIPTION: Hull is complete, as pictured below. Engine is frozen up with minor corrosion, gas tank is missing. Included in the auction is the engine manual and the Owners Manual. This website Welcome to Jet Board Help ( /jetboard/index.html ) has valuable free information and links to help restore this surfboard to running condition. It really needs an overhaul, and a new gas tank (at scooterhelp they used one from an old lawnmower) but with a mechanics help you could get this running again. The 1960's SURFBOARD COLLECTOR AND PRICE GUIDE book lists this on pg.43 with a "Condition 5" average value of $2400, and if near mint (condition 9) at $13,500. I would say the hull is in the "7" catagory...it does have some dents in the aluminium skin, but no holes! A little bondo, and new paint and it would be perfect. The decals are in excellant conditon! If you are looking for a very interesting display piece for your collecton, this is the place! Be sure to see the other surfboards I make!

Here is the history /jetboard/jetboard.history.html

The Jetboard was an early powered longboard surfboard . It is one of the earliest, if not the earliest motorized sufboard, produced from 1965 to 1968 . The original designer was a former engineer from Boeing Aircraft. It was designed to use an aircraft trim tab roller control with your foot for acceleration. There was a simple ingenious safety OFF switch, using a magnet that connected two electrical terminals across a point, located close by the engine's surface watertight hatch. The rider would attach a strap to his ankle with a flexible wire line to the magnet. When he fell off, it would stop the engine.

To start it, there was a flush submerged pull start handle in the top surface of the deck by the engine hatch. Air feed to the engine was controlled by a flapper valve vent forward on the nose of the board's top surface. It sucked air in, porting it to the stern (or rear) of the craft. It was constructed of a heavy marine grade aircraft aluminum alloy to withstand the saltwater conditions it would be used in. The hull was self bailing via a venturi effect off the grated forward water feed port, on the bottom of the board, that exhausted through the jet drive nozzle to rear for propulsion. It required routine maintenance to keep a tiny vent hole clear of seaweed or debris or the engine compartment would flood easily.

This board wasn't designed to be like a modern jet ski or later jet boards that were completely self powered by much larger engines. The main design principal behind it was to aide a surfer in getting out through the waves, instead of laboriously paddling. This powered board also aided in times of smaller ocean waves to push them along or in order to catch faster waves without paddling. Steering was accomplished by moving your weight around on the board and leaning similar to any standard surfboard. But this board was no lightweight and carrying it any distance (despite its flip out handle) at 11 feet long and weighing 85 pounds, could be a real chore. Even with two people going to a remote access beach to launch it could be more work than paddling a normal board once in the water. In heavy wave action, you would not want this beast coming down on your head, if you fell off. So it was seldom used in rough water conditions for this reason.

With its aluminum hull and unique flat lightweight custom Tehcumsuh 6.25 horsepower engine and its custom Phelon Ignition, this board was indeed fairly thin. It was however remarkably buoyant with only the engine compartment, air vent feed tube and jet tube to nozzle stern, not being filled with flotation foam. Being that this board was only around five inches thick, made it much more like its big log board, non-powered cousins. In the later model, this original engine was further modified for reliability. Originally designed from a custom single cylinder chain ...
