    Cracked intake manifold

    Oh wow, I totally missed all of these replies o_O I found the plate on eBay and ordered it. It arrived today and I went to install it and while I was torquing the head bolts back in, one of them snapped :mad: I guess now I gotta find a new bolt. Maybe I should just replace them all. I've...

    Cracked intake manifold

    The brace was missing when I got this ski and I never even looked into it. I've got an Ocean Pro vortex FA, which came with the ski. I'll have to see if a brace will fit and get it on there. If not, I'll see about custom-making something.

    Cracked intake manifold

    Hey all, I've had my '91 Superjet out on the lake about 20 times this summer, and the last few times it's been running really poorly. I've been chasing down issues and working to resolve them. Nothing has made the difference I was hoping for. Today, I decided to run a more in-depth health check...

    Need your input on new ignition "brain" design

    The example I provided uses ground for both buttons but changing the start to 12V is easy. My thought is that using the factory set up as much as possible means fewer mods and therefore less likely to be installed incorrectly. Sounds like it's pulling the pin up. Maybe try adding a pull-up...

    Need your input on new ignition "brain" design

    Does it boot up and function but not provide any spark, or does it not fully boot up? I wonder if the bootup sequence is trying to initialize the serial connection and it's failing, so it's getting stuck. Alternatively, does disconnecting the voltage divider help? What if you disconnect the...

    Need your input on new ignition "brain" design

    Am I correct that the "Start" and "Stop" are the buttons on the handlebars in the latching circuit? If I recall, the start button provides +12v and the stop provides ground, is that correct? In the schematic, it looks like both transistors are going to try and turn on at the same time. 12V >...

    How I set my ski on fire and then sunk it.

    Don't I know it! Before it was mine, it was my uncles and he left it sitting full of salt water for about 3 years. He had a 750SX and the Superjet both engine compartments were filled with water. My dad and brother picked them up, cleaned them out, and miraculously they both started and ran. My...

    How I set my ski on fire and then sunk it.

    The only thing I could find is a picture of the battery cable. The other pictures I have are the hole in the hull, broken coupler, broken throttle cable, broken fibreglass on the nose, split pump, broken pump shoe, and broken pistons... I do have a few other pictures of things that aren't...

    How I set my ski on fire and then sunk it.

    Indeed. Glad to stay out of there! Thanks, I'll check them out. I wholeheartedly disagree. If there had been no ground between the ebox and the battery, the starter would have simply done nothing. It would not have fed through the stock ground wire as the ebox is not connected to the battery...

    How I set my ski on fire and then sunk it.

    The foam is there and it did float enough to not disappear completely. There were only a few inches of the rear end still above water, but it did keep itself from totally sinking.

    How I set my ski on fire and then sunk it.

    I thought I'd share the tale of how I set my Superjet on fire and then sunk it. This happened last summer. I have been working on fixing up my old '91 SN Superjet, fixing issues as they come along. The list is long and comprehensive, and up to now, almost everything has been replaced or fixed...

    I get it. Sharing incomplete projects can be uncomfortable/risky. I do have some experience designing similar things and was hoping to throw my two cents in, and maybe help design the board if you'd be open to the help. I love the idea of the Zeel, but also building my own. I'm running a measly...

    Need your input on new ignition "brain" design

    Sweet! I'm wondering if there is any chance of sharing the schematic and board view files? I'm no PCB expert, but I've built a number of things and would love to help, if I have any time :) Also, for those of us who would like a new CDI but aren't as worried about using the toothed wheel for its...

    144 pump

    Is the wear ring housing still available? If so, what kind of condition is it in and how much do you want for it?

    Help identifying what's been done.

    Thanks John. I knew it wasn't right. But I don't yet fully understand what correct looks like to make it that way. Me too. The only thing I can come up with is the gasket was modified to let some water in... I only have one cooling line. The other is still set up for the stock bilge. The lake...

    Hey guys! I've been working on the old SN trying to get ready for the season. I've got some more questions about the cooling setup. From my understanding, normally the cooling line comes from the pump, into the manifold, out the head, and into the exhaust. Mine aren't doing that. Reading this...

    Nope. Nothing going up to the bars.

    Help identifying what's been done.

    So I pulled the engine today and found a few things that bring up new questions... isn't that always the way. On the Midshaft talk page, it says "There is a hose with a zerk fitting on newer SN and all larger 701/760 housings". This tells me that the older, smaller midshafts don't have this...
