    The '97 Airbrush SJ Revival

    Apparently I do not have enough to work on. Let's start with some history. I am a big Yamaha guy, reliability, engineering, looks. In my opinion they are the best, others may differ, but that is just what I like. So I started the stand-up scene last August. I entered the game with my family already owning two Yamaha couches found in my signature below. I knew how awesome they were and they have been taken extremely well care of. SO.... I picked up the 440 and always had my sights set on a SuperJet. Fast forward a year and I have a SurfJet project to start, 750sx, and now the newest addition. Please welcome the "far out" 1997 Yamaha SuperJet.

    The story goes that this ski was built by a fellow near the south of Lake Martin. The build was intended for racing, with negative trim system on it. From what I have been told it was passed around a few times but remained between Lake Martin and Smith Lake. The previous owner got it from Smith, himself riding on LM and me riding on LM. He says that while riding on the southern portion of the Lake he was stopped by the original owner / builder and told him the story of it. I like my possessions to have a story and I am sure if this thing could talk it would have one to tell.

    Blah blah blah, enough Zac... what are your plans for this thing? I aim to do this ski right. I am not going to blow the whole surprise for you right now, but here's an idea. I am going to start with touching up the chipped spots of the paint. Come back with some clear, or clear nail polish. I have already begun the search process for parts and have some select items on the way. I will be posting my shopping list soon! Because this thing is JUST a hull and turf. It has some pissers, a hood, and thats about it. I have a 62T in storage that needs a quick checkup, and refreshed carbs. Finally, just assemble this beast. The turf might be replaced because I am strongly considering side rail turf. I am not a huge fan of the purple either, so if you have a suggestion I would love to see it below.

    Stay tuned, Zac

    Re: The '97 Airbrush SJ Revival

    These build threads are really just for my own enjoyment. They really let me get the voices inside my head out onto paper. I do greatly enjoy the thought that other people view these and contribute, yes I know you are out there. Yesterday and today I went out to temporary storage to fiddle a little. There is so much that needs to be done to each ski that its hard to pick somewhere to start. So I am going to focus on the individual ski and keep the build threads separate.

    I do not really like the purple that is on this ski. Yes, it is a part of Yamaha and it will forever be engrained into the DNA of this ski and the 90's. But that doesn't mean I have to like it I don't want to. So I am going to get rid of it. Like I might have mentioned this is MY ski. I am going to keep this girl for myself. That means I will be spending more cash on it than I probably should. So off with the side rails! Off with the front bumper! Off with the purpleness. That means the bilge fitting, and pissers have to go too. What is going to replace all of that Zac? Well, I am so glad that you asked! White white white!! Turfed white side rails all the way around, white turfed tray, silver pissers, and white grips. She is going to be bright and shiny, with all of her pearly whites showing. I am likely going to altogether delete the front bumper as well. The rear corners might be staying to have correct spacing for the sponsons. OH! Did I mention that Far Out came with carbon fiber rear sponsons? Now consider my only other build was a 440. So we are talking low techy techy for my previous experience.

    I had my dad check on the engine, it is out of reach from me in another city, and I was fearful of the result. But fear not! The electronics are still with it. Honestly hunting down an ebox and all of the electronics would not have been fun. Thankfully they are still together and the engine is just as clean as when it was put away. From the pictures, you can see that the XScream waterbox has arrived. It should pair nicely with the Protech pipe (I need carb adjustments) that I just ordered. I want to powder coat or paint the pipe the original Yamaha engine color to match. It will make the pipe look a little more like it belongs in the ski. However, I am getting recommendations to color the pipe white just like the trim. Tell me what you think.

    Other things were observed and noted on the hull, but I am getting tired of typing. They will pop up in the thread later when I correct the errors of previous owners.

    You are really cool! I don't have the knowledge and skills to do this kind of thing. Your story is very motivating! I had a desire to further understand the technical component. Perhaps someday I will be able to figure it out and will repair my jet ski myself without going to the service.

    Thank you so much, I greatly appreciate it. You can get there, just start with small things and work your way up!


    On another note I have more updates coming, lots of parts have come in the mail. SJ parts are more expensive than JS parts, and that's a fact.

    Re: The '97 Airbrush SJ Revival

    Through the month of September parts for the ski came in the mail slowly. I continued taking it apart with the removal of turf. It was nasty and smelly under the front from the years of rain that it had undergone. A really foul smell filled my workplace for some time.
    IMG_2711.JPG IMG_2956.JPG


    I then began sanding the bottom of the hull. I wanted to paint it white to really freshen and liven up the interior. It would also make it easier to see if there was any dirt or leaks in the future. And it really cleans things up in general. I started with 80 grit and finished at 120. I know that I should have followed up with 220 but it's just the bottom of the hull. I was pleased that a lot of the dirt and oil stains came up. It would only make it easier to paint from here.

    If any of you have seen the RSki Rider videos on YouTube you will be familiar with this paragraph. If not, here is a brief history. Two guys have SJs that they 3D printed steering nozzles (of varying angles) for. This made it easier for the riders to backflip stock skis in small surf conditions. I have a 3D Printer and thought that it would be fun to print my own nozzles. So I started with a -2 degree nozzle out of PLA. They recommend ABS (which I did later). The PLA was simply just to prove that it could be done. I am going to experiment with the +3 nozzle and the -2 nozzle.

    The final thing that I accomplished in the month of September was transporting the engine down to my workplace from storage, and glassing the holes in the "firewall." The holes ran straight into the foam. A huge disappointment, to say the least, because I know that there is water somewhere inside the tray. The holes were covered with a single sticker. So I did the right things and lightly glassed them over.

    Re: The '97 Airbrush SJ Revival

    October and November were slow months for building. My main distraction was flying, it took up a good deal of my time during those two months. December is when the build really began to take place.

    The next step after glassing the holes was to sand and prep the interior of the hull. It some time to accomplish, but the tape really got me excited to continue. So I taped and masked up the parts that I didn't want fresh white paint on. These parts were the rear bulkhead and upper parts of the walls. Finally, I masked off all mount locations. I did not want to clog the screw holes, but I also did not want to add any extra layers and thickness.

    IMG_3620.jpg

    IMG_3624.jpg

    IMG_3618.jpg

    IMG_3623.jpg

    With everything masked off how I wanted it, the logical next step was to paint. I chose white appliance epoxy in a rattle can. It is a little heavier than typical white paint, and its just to reveal and dirt and leaks on the inside of the hull. I went into it with the mindset of "this does not have to be perfect." With low expectations, I painted away. It came out well with only a few drips, luckily they are in places that are going to be well covered by hardware. Results below.

    IMG_3648.jpg

    At this point, it was nearing the time to return home for winter break. So I started the turf removal. I assumed that it would be a simple project requiring patience, but that it would be fairly simple. I was only half correct. It did require a lot of patience and was not fairly simple (or as simple as I wanted it to be). It was nasty, foul-smelling, and just gross. I did accomplish some removal previously, but this is when I really clamped down and went after the turf with chemicals, scrapers, and some light sanding to prepare the surface for new white turf.

    IMG_3615.jpg

    Now it really was time to drive home for break. I loaded up the ski, secured it to the trailer and put a cover on it to prevent any rock chips, and hide the project. It really looked to be in rough shape as most things do with old turf stains. I did not want to parade it around yet.

    IMG_3675.jpg

    IMG_3676.jpg


    One of the last things that I needed to check on was the carbs and crank seals. So I ripped both of those open. I came across a very pleasant surprise. A little history, this engine was a couch motor that we have had since new in '95. We have had the opportunity to treat the fuel for the past 25 years making sure to rid it of any ethanol, bad, or expired gas. This made for an engine that was clean as a whistle inside and out. The carbs were no exception to that. Here they are with just a touch of sediment in them. Next to nothing at all.

    IMG_3496.jpg

    IMG_3499.jpg

    IMG_3500.jpg

    Finally, the SuperJet reached her home for the month of December. I started throwing parts on to motivate myself. I knew at the time that it would be worth the build, but I wanted to see the light at the end of the tunnel. After mocking up the pole, bars, and nose piece I was excited and ready to continue forth.

    Re: The '97 Airbrush SJ Revival

    As she reached her main assembly place I was able to get almost everything on the interior buttoned up. I had one of my friends help me solve a few issues, and she was ready for a run. The video of that is below. Note there is horrible pump noise that needs to be corrected, and a few things on the inside needed finishing. I tightened a few hose clamps and just cleaned up in general.
