    The 80 SurfJet

    A new project has landed itself a spot in the collection. For now here is one picture, after it received a bath.

    Owned 2 of them. Def low on speed even for a 180 lb rider.

    That seems to be the consensus for these machines. There is certainly a cool factor to them.

    Re: The 80 SurfJet

    So it begins... Hopefully each and every one of you and your families had a nice Easter. The Bunny came early yesterday for me and arrived with this in the bed of his truck. I am not going to give any more details because I do not know if he wants his identity to be revealed, but he has been very generous, and helpful to me.

    So let's start from the beginning, this one has likely sat outside all of its life, it is/was nasty but has now been cleaned. It turns over with the pull cord and seems to have compression. I have not tested how much yet. The board is split right down the seam with a clean break 95% of the way around. The rest oh the hull around the engine is still bonded together. By carefully lifting the front of the hull you can view the foam inside of the board. It has begun detaching from the board and likely can be carefully peeled completely out in one whole piece.
    Let's take a look.

    Upon further investigation, we can determine that not only has the board sitting outside for some time, but that dirt dobbers have made several nests.

    The engine has also been subject to the dirt dobbers but has moving linkages, and turns over smoothly. The pullcord works, but retracts slowly. I am sure that there is more work to do inside such as cleaning, and of course a carb kit. Etc, etc...

    I am aiming to re-create the stickers all across the board including either re-making this one or leaving it as is. I am not sure yet though we can attempt to read the sticker and determine that it was assembled July the 8th 1980. As this is the year of the board.

    A clean spot was made.

    The final product after cleaning.


    To finalize the this post I want to sum up my goals. I aim to disassemble the ski take the engine and pump to wherever I am located and get it purring and painted nicely. Next, I aim to find imperfections, re-glass, and seal the hull back up. I do not yet have a current plan for re-foaming the interior but I have some ideas. Then I can re-paint the entire board, along with the Js440 when the time arrives. Finally, the engine and board will be assembled and ridden.

    But what about my standards for the process? I want the board to remain as original as possible. From mechanics to graphics I want to re-create it all wherever I can. This is not going to be an easy feat by any means, but it sure will be fun.

    Re: The 80 SurfJet

    The past few weekends I have been busy with the 440 so I haven't been completely focusing on one thing at a time. But I was able to provide the SJ with some love these past few days. I started by examining the engine and making sure there was not anything obstructing the engine or keeping it from spinning freely. I removed the pull start mechanism and noticed that the stator coil looks as if it is brand new. One piece of this engine was very sheltered and this was it. I then proceeded to pull the plugs and take a look at them. The top one looked perfect, crisp, no extra oil, nice and clean. The lower one... well it looked like there was dirt in the cylinder based on what I found. Alabama, or at least my location has lots of red clay at the surface and this was certainly evident by the board and the dirt dobbers nests. I then took a few pieces of fuel tubing and carefully placed them into the cylinders. I aimed to pour a bit of two-stroke oil into each cylinder with the hopes of lubricating this ancient engine. It likely had not seen fuel in 30 years. So with a bit of oil in each cylinder, I took an old fuel tank and a brass adapter and placed it into the feed line on the carb.

    Many many pulls later it kicked to life ever so slightly. Just enough to make it seem like there was a light at the end of the tunnel. Continuing on this old pull starter I yanked time and time again until it finally lit off. The engine idled as if it were just woken from a nap, quietly, calmly, and without any misfiring or hesitation. At the time I honestly could not believe my eyes. The small engine had come to life just by adding a bit of precautionary oil and fuel. It soon died from fuel starvation as the accelerator pump was not connected, so I hitched the trailer and made for the boat ramp. The results are the same, after a bit of effort the engine came to life. Here is the evidence.

    Thank you all for reading this far, I aim to continue the project in the summer. Although I am unsure of the rate that I will be able to proceed. The summer months tend to be the busiest time of year for me, yet I am hopeful that I can continue to wrench on this project.
