Need help on buying a seadoo.

Hello,

since I'm not too good with mechanics, I was wondering is the motor 787 and 787 RFI the same? If not which one should I lean for?

Thanks

Thank you very much everyone for your feedback. I might just wait and find a great deal for a ski with a 787. I'm located close to the montreal area. As for the taxes, its about 14% if Id be bringing a ski from States to Canada, unless there's other fees that I'm not aware of.

From what I read, my best option would be 96-97 GTX or 98-02 GTX RFI as kicker mentioned.

Bringing seadoos into Canada is a breeze. No duty just provincial tax. The real pain is bringing a seadoo into Canada on an American trailer. There's separate tax and duty on the trailer plus import fee plus a provincial inspection needed before you can insure it. Far better off bringing your own wagon across the line and buying just the seadoo

The motors are essentially the same engine, just the RFI is set up for fuel injection and the other is set up for carburetors. They are both just as dependable. I own both and prefer the RFI. But would not shy away from a carbed ski.

Hey guys,

I<ve found a Seadoo GTI 2000 with a 720.

What do you guys think of it?

Shoudl I still be looking for a GTX 1998 with a 787 rather than the model mentionned?

Also, is there a big difference between a 787 and 720? Sorry I'm not too good with motors and so.

Thanks

It's a 951 motor with 130 HP compared to the 787 with 110 HP.
951 is more power but a tad less reliability... and harder to work on (at least in a GSXL) the GTX will have a bit more room but you still need knitting needle arms with 3 elbows to get to everything.. :)

:lol: You have to have those when working on my Bimmer also. Why??????

a 720 in a GTX hull (3 seater) will be quite under powered... the 110 HP is nice, the 130 even better.

most people on this forum regard the 787 as a good balance between reliability, HP, and mechanic serviceability.

I personally like the 951, but that's just me. so much in fact, I have 5 of them at my house lol.
 
SabrToothSqrl, can you tell me which model actually has the 951? I see a 1998 GTX Limited and it says it has a 1000cc, is that a 951 motor? Sorry for not being too informed in these kind of stuff, but we all need to start somewhere and everyone's help is greatly appreciated.
 
Here is a reference for models up to 2002.
Typically LTD's are 951 carbed skis (which some call 1000cc)
DI skis are Direct Injected 951's
RFI skis are Rotax fuel injected 787's

Technically the 947 is the name of the motor and 951.2 is the cc (cubic centimeters)

Thank you very much kicker for that link!

I'm debating between the 1998 GTX Limited(947) vs 1997 GTX (787) since both are carbs skis.
 
They are both great skis. Be sure to do a compression check on what ever you buy. Most times the 787 last about 100-200 hrs longer then the 951. But the power of the 951 is quite something.
 
Thanks Kicker. Its greatly appreciated. Now I must find out how to check the compression of the skis.
 
Thanks guys... I've managed to find a GTX 1997 for 3000$. Will be looking at it and sending it for an inspection and verify if everything is working properly.

Everyone's help and suggestion was greatly appreciated and now I can't wait for summer to arrive.
 
For $3000 I hope it a least comes with a trailer. Its not an outrageous price for the area but it should be in real nice shape. Do you have any pictures you can post? Compression is concern #1, then the computer, which is easy, if it runs the computer (MPEM) is fine. If your committed to owning a ski get the compression tester, it is still gonna be your best troubleshooting tool. It is not difficult to use.

That being said, even with a thorough inspection, it will not tell you everything without a water test. Most running issues are not evident until it is in the water and run under a load.

Here is a good thread on things you or your mechanic can look for. If you have questions be sure to ask, you will be amazed at what you will learn here and how simple these skis are. Dont be intimidated the basic stuff will come easy if your willing to throw a bit of time at it.

Thanks kicker. Actually yes it does come with a trailer + tarp to cover the seadoo.

I haven't seen the ski in person, but I've seen some pictures and it looks in great shape.

The inspection is to verify the compression, ware rings, impeller, turbin, etc. I'm really not a mecanic and its a bit far from my place so I'll bring it in a boat/seadoo repair shop for the inspection, since they'll actually know how to do all the stuff for the inspection.

The only thing that I would like to do but I won't be able to, is test drive it in the water. But hopefully the techniciens inspecting the machine will be able to verify about everything.

As for the hull, what should I be looking for? Cracks?

Also, in canada do we have: data tags?

Thank you for the link, I'll check that out.

Guys are 1997 GTX Motor all RFI?

I see in the manual Bombardier-Rotax 787. Does that mean its RFI or it can be a carb?

Anyone that has a 1997 GTX, maybe they can chip in some info.

Thanks
 
I just sold my 97 GTX. I loved it, it was an awesome cruiser but still has great power from the 787. Also very reliable if it is well maintained
 
Yes it's a Green and white 97 GTX.

Happy to read this information because I wanted a carb version :)

It just shows how much I know about mecanics. :) I'll learn along the way.

If you click "seadoo parts" link at top of the page, you can navigate to look up the year and models produced based on either year or model type, there you can see what was available.

The injected 2-strokes were a real leap of technology, some manufacturers failed miserably at their first attempts.
 
Thanks all. Just wanted to say I grabbed myself a 97 GTX with a 787, but it needs a bit of work on it, but I'll manage it. :)

Everyone's help was greatly appreciated.
