SX/SXi/SXi Pro Which is better Js300 to 750 or 750 sxi?

Hi, I'm currently trying to decide between two jet skis and i wanted some other peoples' opinions. I want a ski that would be faster and have better acceleration.
1: http://detroit.craigslist.org/okl/boa/3363712065.html This is the JS300 to 750sxi conversion
2:http://fortwayne.craigslist.org/boa/3307416458.html This is the 750sxi jetski
I am worried that some of the conversion, adapters, and construction might not work correctly, but i do want a faster, more agile jet ski. Also since the js300 only has a js550 pump, would it be slower? Any opinion with a explanation would be great, Thank you.

Please no recommendations toward superjets, i cannot afford or find one.

The 300 will be slower because it's handling will be poor. It is light and will come out of the water easily. It will not hook up in the corners or carve very aggressively. The 750sx will smoke the 300/750conversion even with the same pump and power. The 750sx is a heavy and somewhat clumbsy ski, so if you were going to be doing some free ride, there could potentially be some debate, however, if you want to race, the 300 is the wrong place to be.

The 750 will also take larger pipes if you upgrade.

They are both on the upper end of what they should be worth in my area. I wouldn't pay either of those prices. $2200 is too much for the 701 SN, and $1500 is too much for a 650 square in my opinion. I would expect to knock the 650 down to $1000 and the 701 to $1500 at the most. I personally wouldn't pay more than that. I bought my RN SJ for $2800 on an asking price of $3200. If that guy gets hung up about $2000, just keep looking for a newer 62T that is clean like mine. Skis may be harder to find in your area and worth more, or less desired pushing the price down. I just don't know about the prices in your area, so don't get stuck on my price suggestions.

The 90 is going to have the 650 motor which may be enough for you for a while. The money you save on the older boat can be put into upgrading the motor. The '94 has the 61X motor, which is going to give you close to the same power as the 62T but the 62T is a better platform. The difference is negligable because the difference in power is made up in a difference in price. You can buy the 650 and upgrade the motor with the money you save, or buy the 701 and leave it be.

The parts are negligable. The 94 has more parts of use, but those parts are pretty cheap. The 90 has the aluminum handle pole which isn't super important but if you want that pole it's much more expensive to buy later.

In the end, I would buy which ever ski is going to be the cleanest hassle free option. I would buy a clean 650 over a rough 701. I don't want the problems. I'd rather have a weaker ski I can ride all the time than a powerful ski dismantled in my garage. Take the cleaner one, beat them up on the price and upgrade as needed. I personally would lean towards the 90. Cleaner is more important to me than anything, and they both have the same pump and hull, so you can always change the 650 motor later on for a 701 or w/e.

Just my opinion, others may disagree.
 
If that 701 goes for that much in the winter time I would be suprised. Also the one with a 701 obviously had a swap probably from a WR3(location of the plug wire holders on front of the cyl head). Looks a little messy for that price, Id look at it carefully to make sure everything was done right. If i were to pay that kinda of money for a SN id go with something like this. http://www.x-h2o.com/threads/111423-Superclean-Modded-SN-Superjet&highlight=squarenose+superjet I picked up my SN with a 650 for 900, needed a little work, but lasted me all season with no major problems. I have to agree with Vumad, if you looking to get something and just ride, get the cleaner unmolested ski and ride it till you need to upgrade.
 
Thanks for the suggestions, i did notice the prices were quite high for a 22 year old watercraft. Unforutantly, I have zero experience with these jet skis(I've ridden one twice) and even less experience with engines. They did look slightly weared based on the pictures and definetly not worth what they are asking so i searched a bit more and found a few that are better deals.

This one looks like a good way to go. It looks pretty clean. It has a pipe. The price is fair. You need to look over it real good for signs of wear and make sure you are buying something that has been well maintained. There are plenty of posts on the forum about how to select a ski that wont break quick.

A starter is not a big job. You may not know how to work on a jet ski but if you are mechanically inclined you should be able to handle it. You just have to remove that pipe to get to the starter. You should be able to replace it w/ only removing the pipe. At least that is the way it is on my Kawi, I haven't had my SJ pipe off yet.

http://www.reachoo.com/ads/79256699?utm_source=yakaz This one isn't a bad gig either. A pipe and a head. The pole looks funny because it is from a 96+ RN SJ. It's not a SN pole. Usually you have to buy a bracket to make that pole fit. I do not know what the SN pole bracket looks like, but there's a good picture of what is on the ski. Maybe someone can tell you from there.

That would be a tough decision. The 1st one is simple and ready to go. The second one is a bit more expensive but looks like it has better parts. Again, I would say make the decision on which one is MECHANICALLY cleanest. When I say buy something clean, I don't mean pretty paint. Look at sit down ads, they always post pics of the hull and none of the motor. I want the up skirts, because the mechanical parts are what are important and most expensive. You can ride a ski with a :):):):) paint job, but you will be wrenching on a ski with a :):):):) motor.

I would lean towards that second one with the blue pole for $1600. On the outside it looks rough, but it reminds me of a car covered with bondo because someone is always trying to tune it to perfection and not wasting any money on paint. Power is performance, and you don't get any power from paint. Stickers however, they give mad HP, so buy the nicest motor and slap a protec sticker on the hull scratches.

Edit: Second one does say aftermaket pole bracket, water box, prop, etc. I'm liking that second ski. http://www.reachoo.com/ads/79256699?utm_source=yakaz Lots of good parts that look real clean. All those parts installed on the cheaper ski would end up costing you way more than $400. I just spent almost $300 to get a similar AM head. That $1600 with a coat of paint, foot holds and some turf would be a sweet ride. If that thing is as mechanically clean as it is in the pics, grab it up, rock it out, and when you decide to take some down time, foot holds, turf and paint.

I know its a great price, now to just get the funds :\

Save up about $2000 so you are ready to buy a ski. Keep looking so you have an idea of the asking prices. Remember, listed prices are not sale prices, so figure it will always be less. $2000 does NOT mean you should spend $2000. $2000 is the amount you should have in your hand to get you the upper hand in negotiating. Money talks and having $2000 will let you buy any SN SJ ski you want and cash in hand means you pay your price. If the inside of that modded ski is as nice as the outside, it's a good price with all those parts. Try to knock it down another $300 if you can, but $1900 is probably fair. *clean is more important than mods* Worn out aftermarket parts suck.

If you don't get it, don't worry, the best times to buy a ski are just before christmas (about 2-3 weeks from now) and February /march. People need Christmas cash and this later it's been so long since they have ridden they figure they just sell, and during that time, no one has the itch and prices drop.
