hi guys,,,where can i buy a 787 engine for 1997 seadoo challenger?? any recommendation??
i saw one at SBT cost $845??? any experience with them?? how much did it cost you for shipping?? and do i need to swap them my old engine?? thanks a lot guys...i'm a bit lost and need help.
 
SBT's prices are at the industry standard. And yes... you have to send your old engine back to them, or they charge you a BIG core price.

They have a shipping table on their site, but to AZ, I think will be around $75.
 
what ALL do you get for $845?????

I found my own answer. except it says 1997,1999 seadoo challenger 1800. I assume it's good for the 1998.

I dont need one. I just want to be on top of things when I need them.

there is another option of having your engine rebuilt from fullbore.
Difference is you get your old engine rebuilt with one year warranty vs SBT core exchange with two year warranty,

choice is yours.

Given the option, would you go for the WSM Platinum pistons or the Pro X pistons?

The Pro X's are 80 dollars more to use with the top end kit... that seems like a lot. Any opinions on if its worth the extra money?

personally not owning 787 engine but being familiar with longevity of
2-stroke engines on what I've read, keep it as stock as possible.

The best thing is work on jetting/airflow/exhaust. all three will allow less restriction and not affect internals.
Anything outside is looking for more tear downs and at least for me I like reliable.

so neither in your question but closest thing to stock would be preferred.
Some say OEM piston but I would upgrade connecting rod if need be.

edit: looked up both and i would think the Platinum pistons b/c of the reducing friction.
Also saw your in a rebuild yourself. If you need the top end redone fullbore has it where you send in cyl heads and they do it for you for 295 Platinum kit or 10 bucks less w/o if your diy??

Right, thats what i quoted in my post.... someone mentioned fullbore, so i was chiming in to get an opinion on the two different top end rebuild services they offer. It does not look like they have OEM pistons... only the WSM Platinum or the Pro X.

i asked if it would be better to go with their WSM Platinum top end rebuild for 295, or their Pro X top end rebuild for 375. I was inquiring if its really worth another 80 bucks to get the Pro X pistons over the WSM Platinum pistons

I apologize for being unclear in my last post

no need to apologize :cheers:
I went back to site and saw difference b/w two. Dont know where I saw the 10 bucks difference b/w two kits.

I would be stuck to b/c lets face it 80 bucks is not going to break bank but it come down to reliabilty and performace.
If the pro x pistons are higher compression i would go for the platinum ones.
Higher compresssion bigger bore more problems.
Keep it close to stock as possible..
 
I have used Fullbore for top end rebuilds on a couple skis. 587 and 787 engines. Awesome work, turn around time was a little over a week (i'm in canada). Overall great job. Will be using again this spring on another ski as well.
 
Robster,

I am in the exacty same situation, I recently bought a neglected 1997 Challenger 1800. The port side engine needs to be replaced and I am trying to figure out who to buy from. SBT has their engines with a two year warranty for $845. There is a guy on the web that sells out of PA and has the Pro X pistons and what not for $699 also with a two year warranty. I NEED a new motor before it goes into the water so let us know what you end up doing and good luck.

Where in PA?
 
DO NOT use that guy, he has a spotty record at best; I had a not so good experience with him as have others. If you go to pwctoday and search under the "general" section with the terms "anybody heard of this guy", the thread will pop up. He has bad feedback on ebay as well.
 
Hey everyone. I too am looking for a pair of engines for my Challenger 1800 since I have bought the boat with no engines at all :(
Does anyone know whether I can use any other kind of engine (perhaps a better?) or DOES it have to be the 787? I'm having trouble finding a pair of 787's in Europe :( Maybe I just don't know where to look (?).

Any hint is truly appreciated.

Totally new to the world of Seadoo and really looking forward to start fixing this baby :)

As far as a conversion...I don't know. For an engine I would suggest SBT, they are an exchange program as in a core exchange. Google "SBT seadoo" and it will pop right up. Don't know if they ship to Europe though, worth asking. Ebay has some usually.

Thanks a lot for the quick reply. Was just wondering whether any other engine had the same "footprint" as the 787. That would increase my possibility for finding a pair of engines for this boat.
I'll try to contact SBT and see whether or not they'll send to DK (and how much they'd charge for that). Meanwhile, please everyone, do not hesitate in recommending any ideas that can bring me a step closer to a pair of engines that I can use for the Challenger 1800.

Cheers :)

You write English well for a Dane. :) Good luck with the hunt.
 
787?...

The 787 is my fav motor. Right now, I have 4 of them in my shop. This motor is a very fogiving motor, even if neglected.

Before you elect to replace it, if your capable, you should see if there is anything you can do to save the one you have.

If the motor is locked, remove the head and cylinders to see if you can turn it over by hand. If so, the upper end is in need of attention. To see if you need a cylinder replacement kit, remove the rings and put them into the cylinder, then measure the distance between the rings where they come together. Your clearance should be .013" +/- .003". If this checks out, then check the piston to cylinder wall clearance. You should be getting about .005" to .006"... If there two measurements are good, the cylinders are good, no visible marks on the cylinder walls or pistons, then you might find just honing and rebuilding with a new gasket kit could save you big bucks.

If the compression is good but you have a "ticking" sound, then you likely have a bearing issue in the crank. Again, you don't need to replace the motor, just do the lower end. THere is a crank exchange program with SBT. You can also do this if your having problems with your motor hydro-locking on oil from a bad seal of your rotary chamber..........

Good luck, but if you do decide to go SBT exchange, please follow all the guidelines they list in breaking in the new motor. And most important, if your old motor blew, you have got to find the "ROOT CAUSE" as to why it happened, or you'll likely find a motor that won't last long.:cheers:
 
Hope you got that boat really cheap since it doesnt have the engines. It is gonna cost you quite a bit to get 2 of them shipped to you. I would guess that 2 rebuilt motors with no core and shipping across the ocean would easily cost $3000 US.

Man...you are prob better off finding another boat and parting that one out...that is gonna get uber expensive.

And no...no other motor will transplant w/o fiberglass work and other major headaches.


As far as SBT...it is a bit cheaper to do a standard w/ a 1yr warranty vs. 2 on the premium. Their prices have rose considerably in the last few years, and are only shipping air, so that is more expensive too.

It used to be the best deal out there for a very well done motor, but it has gotten to the point where having your own rebuilt is about the same...and you know you have higher quality parts.

SBT also uses parts that arent as durable as OEM and other aftermarket parts.

If you are a normal rider with a stock machine and doesnt ride it like a rental...SBT will suffice. But if you are modding it, or beat the piss out of it all the time...rebuild with quality parts and a reputable shop.

That guy in PA is a complete joke. Stay far away from him.

Pro-x pistons are a MUCH higher quality with much tighter tolerances than WSM. It worth the $$ dough if you planing on keeping the machine a long time. If you are planning on upgrading, WSM it and sell it.

Does the engine have to be running to detect the ticking sound? The guy before me put that cheap 2 stroke oil in it and fouled up the cylinder walls. I know they need replacing in one way or another. Would using that cheap oil damage the bottom end as well? Trying to get this thing on the water, just don't want to spend money where I don't have to.

Well, until now it cost me abt. 2.5K USD. So, only time will tell how much I end up using on it before the fun part can begin :) At this time, I would be willing to pay 3K USD for a pair of good-condition-engines. But first priority is to find them a bit closer to me geographically, you know, just in case...

Once again, thanks for all the input everyone.

And thanks for the compliment YUOnDaGround :)
