Hey guys,

Thx for the info and advice. Yes at the moment i'm trying to get as much quotes and info as possible. Only thing i did was to give the Ski a wash inside out and a polish:D had to do something:p

Anyway, i think the best option would be to get a whole engine. The one Lou suggested fro that seadooengineshop looks like the best option for now but like we said, postage would be expensive and i need to find a blown engine for them. I didn't get a reply from them yet:(
Is anyone of you US guys close to them and could see with them if they are willing to ship one to AUS without being exchanged? Or could give them a call for me explaining them to see if they are willing to ship to AUS, how much and without an exchange engine and if they need an extra cash (giving them this as a last negociating option:D)? I would really appriciate it.

I've talked to Minnetonka4me and i'll be able to get some parts off him too:) like the missing oil injection stuff

I googled and found Jetsports QLD and ask for a few quotes from them. Amoung other stuff i ask for a full second hand oil injection kit but this is what he replied. (Would be best to buy oil block off plate $16.50 you can just premix your oil and fuel.)
I know you guys said this was bull but why would a shop recomend it????

Thats a start :)

I sent you links to machines being parted in Miami.
You can pay ~$100 to get cores. Then I/we send it to who ever you decided to rebuild it. Choices are SES(~$850),SBT($1100) or Fullboreonline($900)
I would say fullbore. Have better reputation.

Then I can get you the other parts if interchangeable for your xp

As far as premixing or oil injection it your choice at the moment.
Oil is special API-TC stuff that is not the cheap blue TCW-3 two stoke oil.
So a gallon is $30 and you will go through a lot in a season if you ride a lot.
Two strokes are not fuel efficient especially with 10 gallon tank.
Engine you get in long block can have intake with new dual or single carb intake with oil injection on it already.
So you either leave it or block it off.

Thats cool, are you/or anyone else far from Fullboreonline? and can find a core and drop it off to them or ship it to them?
As only a rebuild short block in AUS is 1450!!

Is that from the core engine or the new rebuilt engine?

Only major thing would be postage. Would you or anyone be able to organise and find out what it could cost? I'll also try and email them and ask.

I'm thinking it would have to be shipped as freight, at least to make it somewhat affordable. FedEx and UPS both ship to Australia, I have no idea how much it would cost. Probably the best thing to do is to contact whoever is going to supply the motor. I would also tend to recommend Full Bore, simply because they have been around longer and I have had personal experience with them.

Lou
 
Yeah, i'd go with freight or what ever the cheapest way to send it is.
BTW, what up with you guys VANDELAY pics:)
 
Yeah the cheapest the better.

I need to see with 'ocod' if he is willing to grab a blown core and organise it for me. If i could get the full thing with carbs and the oil injection kit etc from one of the adds he showed me, get the core rebuilt and then ship it all back with the other bits would be ideal i recon. But first knowing the postage cost would be nice...

BTW whats up with the VANDELAY pics:)

No those are rebuild prices at places most use. The $100 is to get a core vs sending your in. Most places won't pony up core unless you pay big $$. Thing is they have other parts you need.....
Here's Fullbore. They offer a 3 year warranty on rebuild $950.
http://www.fullboreonline.com/specials.htm

Thing is your parts suck. Every one has been eaten away.
You can pick core in better condition to rebuild easier.

If you find long block from 99 or minne you can request them find you a single intake vs dual.
That's what I did and running a 167.5 in the main jet of one of the dual carbs. Much easier to tune and less part to worry about

Thats easy. What gets to you?? US Postal Service?? UPS or FEDX
Calculate the L X W X D of a large rubber maid crate weighing over 100 lbs
 
Lol at that Vandelay thing:D


Ok so newer 99 block and single carby. Will that truely make life easier? would everything else bolt straight in or would i need mods? I've had my experience with mods doing up my car and don't really want to tackle even more headace than i have already. Also performance wise, what would the newer block and single carby give?

Would you guys give me a better estimate of the large rubber maid crate as i don't know what they look like and the weight of the engine with carbs and oil parts.

Thx
 
I don't want to make this difficult for you, but you will need an intake manifold, to tell you the truth I'm not that familiar with with a one carb. setup. I'm not sure about the airbox setup and the carb. cable. Ocod could probably advise you better than me, since he's done it.

I would advise strongly that you keep the oil injection system, it's going to make your life a lot easier in the long run. Do you know if you have the parts?

I imagine someone sticking their head inside of box then standing up scratching their head saying now where is that part :lols:
Core motor or the one from 99spxxx or minnetonka if they have it will be included.

You need to get new air box single carb plate as you have one with two holes.
Haven't gotten around to installing it yet through. Sounds like a CAI in your car when the butterfly opens up.


edit: Sent out request for cores and pumps from those two ski in locally. I'll let you know more when I see them

edit: checked shipping to Perth. Damm that is expensive if I did it right 800-1200 bucks

I have lots of pumps, carbs, etc and between me and my brother we can come up with a decent core and/or have something rebuilt if you wanted.

The crates I use are:

Depth (in.): 31.25 in
Height (in.): 14.55 in
Width (in.): 21.25 in
 
Jetsport are pretty good, theres also a guy in perth called "Jet SKi Eddie" or even Seadoo Central may have some usable second hand parts you could buy

Wow, those shipping quotes are really crazy. If i can't get them lower might be a similar price to get one locally. But we knew and was expected to be high:(

Thx MAC for the Perth names. Would you have phone numbers? I'll try and look them up.

Plus it would be better shipping everything once from one place and you would know exaclty what i would need to make the engine work with one or two carbies as ocod suggested...

Also guys, would having one carby, will it really be that much better than two?

Any by the way, while all this is being put together, i wouldn't mine adding a few $$ and parts to get a little bit more out of the engine. I don't really want to mod it to push it to its limits and blow it after a few months but would be keen just to give it a little extra:)

Shame postage is this high. I'll need to find something cheaper....

Minnetonka4me, when you say have something rebuilt if i wanted, Does this mean you will rebuild an engine for me? This might allow me to save from buying a core and getting it sent to those rebuilt places. And if thats what you mean what would that cost?
 
I've been thinking about your situation. I'm thinking, with the costs of shipping, unless there is a significant price difference you would be better off getting a re-built engine in Oz. The reason being the warranties, with full bore you would get a three year warranty, but the problem again would be the shipping, you would need to ship the motor back and they would ship you another one. Again the shipping would be cost prohibitive. So if you get one from the US the warranty would not be a significant factor, because you couldn't afford the shipping.

Lou
 
True but like i said a short block is $1400 here. I fear to ask what a full one would be. Plus i would need all the oil pump parts etc that is no where near the price Minnetonka4me has told me. If i can find a way to get the postage to be half i'll be happy:)
 
Wow.A lot has happened here in 24hrs.Guyph.You have some great advice here mate.I now have 4 days of so I won't miss as much.Pm me if I can do anything for you.I may know a guy who might have a way to do this for you.I just need all the motor details and I could ring him.He is a very very good mechanic and you'll get all the warrenty etc.
 
The weight is the major factor; it costs close to $100 to ship a shortblock in the US these days...so I cant imagine what it is to OZ land...
 
Guyph.I dug this guys ph number so anytime mate I'll ring him and he will give me a figure over the phone that will be pretty close.(considering he hasnt seen anything)At least its a number to start with.
 
I've known this guy and his family for a lot of years and he looked over my ski b4 I fired it up.Just to be sure.Bang.It fired up and nothing needed adjusting.(that was these guys that helped that happen)He about 40 year old and not a young mug.Hope this helps
 
Crisso, If i can get an engine locally that would be great. Plz let me know what you can find for me. I know shipping with e-go here in aus is quite cheap:) Let me know...

OCOD, The newer 99 block, what model does that come out of? Maybe i can widen my search of engines in AUS if thats gonna fit:)

If i can get the engine in OZ and them get the other bits from Minnetonka4me that would work out great:) all depending what its gonna cost....
 
Hey man.Ill ring the guy tomorrow and see what he's got.I'll get info on short blocks and up from that.
What motors can be used?So the choice is wider.
 
Crisso, Thx for the help. If you don't mind im keen to find out what you can come up with and keep my options open
Well engine options i'm not sure, maybe ocod or Lou or Minnetonka4me can confirm what would suit.

Big thx to a member as he has found another option for me. I hope you don't mind i post the pics. Will reply to your pm:)
Would anyone know if this is the 717/720?

enginew.jpg



Basically its from a inflatable jetboat that sank! At least the engine is complete with everything. and best thing its in PERTH so no shipping:D Now engine that sank, do they need only a top end rebuild or does the crank need doing? Tho it might be good to check the crank while doing the top right?

What do you guys think?
Also what parts are salvageable and worth $$ off this thing as i was offered the engine if i buy the whole thing... I might be able to sell parts on Oz ebay etc


:D;p, Could i install a 25 30hp outboard on it and get it going like that:)???? lol

Pretty weird looking boat, I've seen pictures of these but I have never seen one in person.

The engine looks to be a 720, pull the spark plugs, remove the plastic cover over the PTO, rear of the engine, pour about 1 oz. of injector oil down each cylinder and see the the engine will turn over by hand. I've got my doubts. If the boat sank and wasn't retrieved immediately the motor is probably trashed. It could be a candidate for a core for a rebuild, the head bolts are not original so it's had at least a top end rebuild.

How does the pump look?
