Will a rxp impeller fit a rxt ?

[Kinchyle]

Anyone know if a rxp impeller can go into a RXT ?

I have emailed impros but still waiting...

[INDY27]

Yes it will, all 4-tec's use the same pump.

Yes the props will fit,pitch different. I have heard that a repitched RXP prop works really well on the RXT. I have not tried it myself.

05Limited is running my old Impros pitched 12/19.5 stock RXP impeller in his GTX Limited with great results.

I'll vouch for that... 71.8 @8100

Kinchyle,

What mods have you done to your RXT?

We've got to run to a powerboat in a few minutes, but let's compare notes later. We might be able to help out with an impeller.

Yes it will, all 4-tec's use the same pump.

well, that's not exactly correct. Not all 4-tecs use the same pump. They all use the same pump housing, but some use different internals. Not 100% sure about the rxt, but, the GTX SC uses a different impeller (155mm instead of 159mm), wear ring, and impeller shaft. The drive shafts of the RXP are considerably larger than the GTX SC/NA's

Not 100% sure, but the RXT may use the 155mm impeller setup also.

The GTX SC,RXT,RXP pumps are the same only the wear ring is different on the RXT and RXP. Yes the drive shaft is larger on the RXT and RXP and the props are bigger but the shaft in the pumps are the same.The early '03 model GTX SC had a Plastic pump housing that was not strong enough to stand up to the power so they all now have the all aluminum housing.

yep I was wrong on the impeller shaft. they are the same (in the metal pumps)

but as a whole, not all 4 tec pumps are the same. 03's (and a few early release 04 GTX SC's) used a completely different pump as Kinchyle said. If the rxt does use the 155mm impeller (which I'm not sure), you should be able to get the RXP impeller to work if you put an RXP wear ring in.

One thing I did notice is that on the riva racing edition RXP Riva used a 14/19 concord. On the Riva Racing Edition RXT, Rivaused a 14/17 concord.


btw I've attached guide for the 04 4-tec pumps.
