I'm thinking about buying one. Who has ridden one or had one.
Whats your feedback on it?

Haha, looking outside our area huh? Apparently I'm looking at the same things you are. It seems like a hell of a buy, but I can't swing it. He doesn't have any pictures where you can see the power valves. I'd ask him to get a better pic under that dry pipe.
There are some on here that have these engines, but it's not very common, so you might not get much for feedback.

Had one last season, stock '06 SJ hull, stock pump with 14/18 concord and WW cone with a bone stock low hour 66E, running stock electronics, stock head and stock powervalves, waterdawg wet pipe, waterdawg upright mounting kit and dual 48mm Riva Powerbombs. The carbs where relatively easy to tune to the motor, the WDK upright mounting kit made putting it a piece of cake, had to relocated one ebox bracket, make a bracket for the powervalve motor and front exhaust mounts. Installation and setup where amazingly easy.
Really ended up being a pretty simple install and it fits in there pretty well. The power was great, I wanted stock yamaha factory assembled reliability but with more power. It had a real nice linear powerband that pulled hard no matter where, blew away all the motors in our group (most exotic of which was an 84mm stock stroke lamey with dual carbs and stock electronics) The motor was heavy but once it was in you really didn't notice it because it was that much more powerfull. It DRANK fuel like it was going out of style and due to the waterdawg pipe I could only run a small tank (had a 550sx tank in it) so long rides where out of the question without refueling. On top of the monster power it put out in stock form there was a ton of potential to make much more power (big bores, porting, higher compression etc.) and it responds well to bolt ons just like a 701 would.
My major gripes with this setup where the small tank, the crude WDK wetpipe (booger welds and regular steel construction), the laydown style pipe also meant you have to be super carefull about which way the ski was situated in the water as to not backflush the water in the chamber into the cylinders. There also was no room for a waterbox so it was LOUD (although it had a much different sound than a 701/760, it was very deep and throaty).
Everybody who rode it loved the power and was impressed by how much it put down, especially in the midrange.
Pros:
Big power, long stroke
OEM reliability
OEM replacement parts
Bigger power potential
Powervalves
Easy to install if you have the right parts
Easy to find motor for considerably less $ than a similar displacement 62t based motor
Cons:
Relying on WDK for nearly all aftermarket and motor mount/exhaust setups
Heavy
Small tank, high fuel consumption
Very few exhaust options
Plated cylinders can't just be re-bored
Extra junk (powervalves, PV motor, bigger ebox)
In the end I found I valued time on the water and simplicity more than horsepower so I went back to a single carb 760 and a B pipe. I miss the power but do not miss feading it gas. Also, not having the testicles to attempt any big tricks the extra power didn't do much for me besides make a bunch of noise, impress others who rode it and make for a good conversation piece.
If somebody would have successfully made a B pipe adapter or B pipe style exhaust that had an over the top style headpipe and utilized a stock superjet gas tank I would have never sold it.

i can almost 100% agree with the nube
i havent given up on mine but i dont ride it either ....
i have 7 standups and 7 sitdowns
i go to ski ananamous on tuesdays and sundays

I would try another one if somebody other than waterdawg made a conversion pipe that was not the lay down style for it.
I think I would have been better off hacking up a stock hull and OEM 66E pipe to make the motor fit.

I had a long conversation with Jeff about the benefit of a Bpipe style exhaust for the 66E, he was trying to sell me one of his fabled dry pipes and said "if I could just get a few more sold, and get them out there people would see that these are the ticket for the 800 making huge power and they would sell like hotcakes" ignoring the fact that nobody has seen the drypipe or probably ever will I told him that he would have considerably more people interested in an over the top style pipe that could fit around the stock tank even if it didn't make as much power as his "dry pipe".
The problem with the stock pipe is it only works the stupid side draft intake (and the giant size of it), the WDK pipe itself wasn't terrible (made decent power and fit in there well) but the steel construction and laydown style where no good.

Pretty sure he his. That's the one I'm talking about. Price is tempting, but I'd rather build something like this myself.

That ski was for sale several months ago, advertised as a 771. I would almost guarentee that its not a 66e.

I would have to say it is a lie, along with the 170hp statement.

it is that one. i knew it wasnt 170hp for sure.
so hwat everyone think it has in it? 771?
how exactly did he get a 771 is that a bored out motor or a motor from another ski?

It isn't possible to tell what the displacement is by just looking at the pictures but it is possible to tell that it is not a 66E. 85mm bore on a stock crank = 772cc, 82mm bore on 5mm stroker crank = 771cc.

From the link RKM posted it looks like a 760 based motor.

I have heard the 760 is mostly a top speed motor but im looking to get into freestyle...
How would a 701 compare to a 760 on the lowend?

With the help and advice of a few on here i built a superjet with a 66e in it...I made my own bed plate,intake manifold and adapted a B pipe manifold to fit(a bit of work but worth it)
I run twin 46sbn carbs and B pipe so i could run stock tank...I also moved the motor back 45mm by using a Blaster 3 stub shaft...The ski handles so much better in the surf with the motor back and like yamanube said its great power.
If you like messing around with skis and motors i say do it but if you dont and just like riding go for a big bore 701 engine.
