Hi guys, I've got a squarenose GroupK 718 sleeper with a factory B-pipe and a blackjack carb had a magnum pump. bearings shredded in the pump, so I've got to rebuild. However, that won't help me this weekend. I do have another stock pump sitting around, but not the large hub to use the 9/15...

Hi Folks, Would like to put a weatherpack connector on my stators and e-boxes to make mixing and matching much easier not to mention e-box work easier! Anyone know for certain what guage wire they are? Thanks, Hbski

ok, so doing a few mods to my SN and have it all buttoned back up. got it started briefly and then buttoned up the e-box and put it back in....went to run on the hose and would only run for a couple of seconds. When I try to start it it will sputter every several rotations and IS igniting...

Hi Folks, Working on one of my hulls this afternoon and noticed after pulling the steering cable out that the steering compression fitting is loose from the hull. Several threads can be seen between the hex part of the fitting and the hull. I cannot get it to tighten back up and I can not...

So, it seems possible that when Yamaha builds the SJ hulls, they put the upper and lower deck together, foam the a$$ end and then install the bulkhead. Has anyone done a re-foam by liberating the bulkhead from the green glue and then re-roaming from there? Seems like if the tray were...

Howdy folks, Looking for a coil refresh. Was thinking of going with the JSS mod of some of my existing coils, but then ran across a thread here that many were bashing them as potentially unreliable. This was the first I had heard of that since many seem to put great stock in them. My issue...

Anyone on here using an otter box or pelican box for their e-box enclosure? seems like it would be a good way to have an accessible box without going through the gaskets every time you need to crack it open...

Hi Guys. I have a couple of 61x/61x 718 group K sleeper engines in SNs........ adding a B pipe to at least one this year. Would a solas mag pump and hooker 9/15 work well with this set-up? Currently running stock pump and Solas I prop repitched by Group K. Also have worx grates and ride...

Hi, Have one hull with pulled out pump shoe inserts. Previous owner had run bolts thru the shoe, into the intake. I want to try to epoxy new inserts in for now. does anyone know a good place to get these inserts in brass or SS? Thanks, DJ

Ok, have a 90 SN. 61x/61x. cdi mod by protec. runs good except when it decides to act up. Thinking electrical as it will go through fits of starting up running for a second or two and then die like the stop button was pushed. Somewhat intermittent though. So, the question is, what are the...

ok, two SNSJs back together, two to go. However, I'll be needing shims for the other two skis for the engines and the pumps. Where can I get those suckers??? Thanks, DJ

Howdy all, So I have 5 ignition coils and I am trying to weed out the best ones to use on my current two SNSJs. I cannot get any of them to even begin to register properly on the ohm meter. No matter what I try I cannot get a stable nor correct reading. one, which I believe is from an 08...

Hi, I have 4 SNSJs in various states of rebuild. On of mine that had a blaster engine transplant has a rubber piece that bolts to the bottom of the case. Is this a blaster piece only or do later superjets have these also? none of my other three has had this piece Thanks, DJ

Hey folks, I am setting up two SNSJs with 718 sleeper kits from group K and have a good prop for one. I also have a skat 9/17 and a solas-s 14/17. I'd like to use one of them for now on the second ski. Which do you think would work better? Mostly interested in best bottom end, top speed is...

Hey Guys, I have a few SNSJs and will be needing parts. Seems like the dealers always need a week or two to get them ordered and in stock. Does anyone know of a good place around that carries some of these parts? like fuel filters, pump seal, etc, etc Thanks, DJ

Hi, Found out one of my SNSJs has missing inserts on the pump shoe, one of the previous owners put through bolts in and there are nuts sticking up in the intake :twak:. may be able to epoxy in some new ones or something, but if not, how hard is it to remove the shoe and install a new one...

So, I bought a basket case SN a couple of years ago. It came with a 650, which I hadn't done anything with. Pulled it apart yesterday finally to find that it was full of water almost to the top of the case. It had to be full for two years, cause I had the thing bagged the whole time...
