SELL THE YZ AND CUT THE HOLE! haha. Sounds bitchin, that would be my answer...

Not to mention , will the panther take that much HP?

-beerjet-

So.......whats up w/ the blower motor?

To clear up some misconceptions about the Panther... I am not really a Panther fan, but was kinda forced to learn a little about them.

Panther's component wise can handle 1000HP sustained in stock form and not break. Since they are axial (like a screw) flow pumps they drop off in efficiency because there is a much greater gap in tolerances inside the pump. As a result the pressure built by the impeller causes the water to backflow around the impeller and interfering with the intake (causing cavitation). Another problem is that the nozzle is so damn big. Because the nozzle is so damn big they flow a lot more water but don't build up pressure. In short, Panthers are great low RPM pumps. They're very efficient out of the hole. I've seen them pull 100, but there aren't many of them doing it. My buddy is doing 80's with his small block and stock panther. Impeller cleared at .0024; not exactly efficient. Maybe Tom can elaborate.

So the parts can handle the power. But the pump just isn't efficient when forced past a certain RPM. HP is needed to get past that RPM.

Aggreeing with you Tom. Thank's for the input. If it wouldn't go over 70 don't be surprised...

Aqua.. lets make that cruiser "HUMP" call your uncle get the time payment plan Tom

Ha!!! Something on this board I'm good at!!!
If yer not mechanicly inclined ...ask yer Uncle what the compression is . Low is good. What type/size of blower. Big is good in my book!!! Less overdrive = less heat in the intake. Yet ya still move air.
4 lbs of boost will wake it up!!! Back the timing up. it'll be happy. Snow boost coolers with straight
methinol in the tank if ya lean on it. REALLY cools the temps without spending a fortune!!
Bottom line....keep it fun and in the water!!!

Thats the "spirit" GET R DONE !!   Tom

Aqua I don't recall the details on what your current set up is but you'll have some bits and pieces and some retro-fitting ,happy to help coach you on this if you need help Tom

Assembled and returned to you running?  If so it sounds like a real good price assuming they are honeing/boring the cylinders and setting clearances for a jet boat.  If you are assembling it depends on what machine work they are doing .  Internal balancing?

Sounds good. Have you had the pump checked out? If not you should find out what your tolerances are in there... In my buddy's panther rebuilding it to go from 34 thousandths to 20 was a difference of 8 MPH in his Haskell, not to mention a whole lot more out of the hole. The only thing left to do is slap the B stator housing on the back for a little more squirt. It's a little tougher to get top speed out of a panther but you can do it. They're not my favorite pumps but you can definitely work with them.

If I'm not mistaken the Impellers are pretty standard... The stator housing is Panthers "equivalent" to the bowl setup on a mixed flow pump.
The B model housing designates use with a big block typically. The B housing has a smaller nozzle than the A housing (usually paired with a small block). So with the smaller nozzle you get a little more go power on the top end. However if you're tolerances are not tight enough you will actually sacrifice performance and get more of a freewheeling effect as the impeller builds RPM and water pressure. As the pressure build it will go around the impeller... The tightest tolerance Panther suggests is 12 thousandths. This tolerance can be achieved by using more or less a sleeve that gets pressed into the pump, very similar to a wear ring in a berkeley. It's relatively inexpensive. In fact Panther will do the work for you including freshening up the pump. They're not unreasonable with their prices. The proof is in the pudding, and I promise all these ingredients work. You could get a lot more speed out of a mixed flow pump, but you gotta work with what you got...
