I just bought a CLEAN 2015 roundnose Superjet with about 20-25 hours on it that is completely stock with a super nice custom trailer for $7500. Is that a good deal as the ski runs good? Are there any problem areas with the ski? The guy I am buying it from said he used Yamahlube 50 to 1 mix, just checking to see if that is right? What grad gas should I use in it 93 or 87? Loved test riding the ski the other day, but let me know if there are any must do mods I should consider right away. Thanks in advance guys!​

Ya, pretty solid deal. You should be able to sell it for that and not lose much over the years.

50:1 Premium non oxy 91 octane or abouts is pretty standard for Superjets.

Ride it a lot, see what you'd like to change. Read up, ride with others, welcome to the addiction. Find new friends that like jet skiing, they'll be the best friends you'll ever make.

Thanks for the reply! I am pretty happy with it so far! Do you know the part number of the spark plugs it takes by any chance? I was going to swap those out. BTW I did a compression check on it just to be safe on both cylinders were dead on at about 150.

Yeah I considered all of those but the one that I bought definitely had the lowest hours and was in the best condition and included a super nice trailer even though it is stock I'm just planning to do a couple of handling mods mainly

That's a great deal and a clean ski! You're really going to like it.

Does the trailer have straps in the back to hold the ski down?

How's the engine bay?

For the stock ski, you just need to run 87 octane per the owner's manual. I've only run 87. No harm running 91 but it's not necessary. You may want to consider running ethanol-free gas. Pure-gas.org shows where stations are, looks like there are a lot around the DFW area. I am picky about maintenance and keeping things dialed though.

I used to run Pennzoil Premium Plus premix, the second link. The XLF is "extended life formula" but I was never actually able to figure out the difference other than marketing.

I started running Klotz Skicraft Techniplate premix oil, which is about $44/gal on Amazon. No issues or specific reason to switch, I just wanted to move to something a little 'higher quality' once I picked up my new ski. It's also orange instead of blue and maybe won't darken the gas tank plastic color, but I have no proof. I also run the oil at 40:1 because a little extra oil never hurts, and it's not enough change to affect the jetting. 2 vs 2.5% oil. Not trying to start an oil debate though. 50:1 is what is specified in the manual.

Yamalube 2W is also a great choice, $36/gal from Rocky Mountain.

I recommend one of these type of bottles for mixing since it has a cap. I used to use the classic Ratio Rite but this is way easier.

Yes I have a strap on the back of the trailer but took it off to get the old girl all waxed up.

The engine bay is clean and all stock will post a pic in a bit.

I think I am going to run 87 Costco gas and probably run Quicksilver or Pennzoil as I have been advised by a few local experts here that they are fine in a stock SJ.

Taking the new baby out 2 days this weekend to get used to her. Then going to buy a grate to improve performance probably but want to get a good baseline.

Oh yea, it's fresh and low hours. Looking good with the wax! I use Hot Sauce to clean it up after coming out of the water, it is the best I have found for water spots and also applies wax.

Looks like someone put a twist in the spark plug wires and therefore the rubber cable stay is not on the bracket.

I moved over to an AGM Yuasa battery because that stock wet cell was bubbling some acid out of the vent in the handle pole and corroding things.

Also, the hood seal on the bottom side has one spot that should be re-glued in the channel.

I agree, Costco 87 and Pennzoil are fine as your local experts suggested. If you are using ethanol gas and will let it sit I would recommend adding Stabil, or get E0. To keep the carbs happy.

I have not installed a Worx grate yet and am curious how it compares side by side with stock. Don't want to lose too much top speed.

Yea I saw the hood seal is loose on the bottom and I am going to sue some superglue to get it back on today before taking it out Friday unless you guys suggest something else.
