Liter motor dreaming...

[Aircraftsalz]

I wouldn't build that SS motor or any motor unless your going to do it like the builder says. Your going to build it on the cheap side, ride it & not be happy & think it wasn't worth it. There's a lot of Xscream motors around us, you can tell the ones that Xscream built top to bottom & the one that are built on a budget. I'm not trying to sound like a dick, I just hate it when someone says I'm not happy with my motor, why's yours hit hard, etc, etc.

Its not just the cylinder that makes these motors rip, its the cylinder, with the xs porting, with xs tuned carbs, etc, etc.

Set it up by the book, ask Idok or Boyer about the local SS crew.


Sell some stuff & buy a complete motor....... Also like Chris & Matt said the mag pump is worth every penny, even without a lot of Brap. Chris is almost landing flatwater BF's off his set up wake with a ltd 701 ported motor, S/B mag pump. I would say he makes it 3/4 of the way, single boat wake plate to plate & no trim.

No matter which builder you go with, I think it's essential to trust them to build you the whole package. That way everything works together the way it should.
That's where the perfect gains come from.
Spot on Josh.

How is the weight diff on the modded stock skat to the skat? Any advantage to buying the new one???

 

[OCD Solutions]

I'll post up weights once mine shows up later this week. I'm expecting up to 5 pounds heavier than stock but the Billet one should be close to that as well.

One advantage to the modded stock one is that it bolts up to any standard stock wear ring.

 

[Proformance1]

Ahhh, I thought the skat was like 9 lbs heavier. Maybe that was the 140mm one, so you think stock modified and reg skat are about the same weight, cool

 

[OCD Solutions]

Could be, we will know for sure once I weigh it. There were some weights posted on Skats in another thread where the 148 was made from a 155 housing with a 148 sleeve pressed in that weighed a ton from all the extra material, something like 11 pounds heavier. 144 and 145 could be made from the 144 housing and required less material.

I'm picking my XS1000 & Billet XS148 S/B mag pump tomorrow. I will stick it on the scale. Boyer did you do a Setback mag or standard so you didn't have to buy another shaft?

 

[OCD Solutions]

I finally listened to you and dropped the extra on the setback pump and extended driveshaft. I spoke to Dave last night and it shipped out yesterday, fully assembled and ready to install. Scheduled to arrive March 2nd.:fingersx:

I don't think I could go setback since my entire Yamaha motor and pump are already setback in my lightweight Kawi hull........just thinking out loud again...

Mat the Stator section is setback in the Pump. The location & bolt holes are all the same. The 148 Billet pump I just got is all in one, no wear ring.

But if you go 144 its a normal pump, just with the stator set back further than a stock pump.

 

[OCD Solutions]

How do you replace the wear ring in those units Josh? Is it just a stainless wear ring pressed into the billet housing?

Pics would be nice...and weight. I am going to start a journal and weigh everything from now on. I picked up a Pelouze 4040 like yours, as well as a 75 lb postal scale.

 

[MADMAT]

None of these weights (billet cases, epoxied OE cases with disaster plate, mag pumps) really matter IMO when you are pushing 865 to 1000cc!

But still good to know I guess....

Gotcha! So I wonder if I would have any reason to do that on my set up??

 

[Aircraftsalz]

I like the Setback set up, it puts the prop way back in the pump. I got my 148 Billet mag pump today. Its a work of art,

Boyer the wear ring in pressed in, so if you had a problem you would have to send it to Pat I guess. I wash & flush my ski's very well, so I don't think I'll have a problem. The 148 & 145 pumps are set up like this. Not sure on the 144 Billet pump.

Weight without prop, but complete with shaft. 11.2lbs
Weight with prop 14.2 lbs

I thought that was great for a 148m pump

 

[masterblaster]

all the reg mag pumps are made from stock housings,The 140 is the heavy one cause the insert is so much thicker. I was unaware you could send them your old housing and save that much $ though. how much extra is it to get the setback and longer drive shaft?

n2..how much more power did those taperbore 38s make on a 701? I was thinking about putting a set on a small lim setup I have. there is no way id use them on a big bore pv motor though,Id go at least a/m 44s,those can be found cheap. Im almost thinking of doing 44s for this lim setup,I tried it with novi 46s and it REALLY came to life,Pretty sure i can get the same performance out of it with cheaper a/m 44s though since i dont need the high rpms anyway

 

[Matt_E]

Setback shaft sets you back ~$400.

Enough to make me finally believe that a non ported 701 could actually pull harder on the bottom than my ported 760. I did them on the Wifes limited 701 setup and was very impressed at how much more snap her ski had, she was complaining because she wasn't used to all that power and it was catching her off guard and tearing the ski out from under her.

You are likely correct that a similarly modded set of 44's might be in order for the 760. The 38's hit hard but i can't help but wonder now what a set of 46's would do on that engine.

 

[MADMAT]

that a non ported 701 could actually pull harder on the bottom than my ported 760.

Total truth!! I hated my 7pigsty.

It's the difference between a 327 and a 454, one is quick, one is strong, just depends on what you prefer and how you ride.
