155 OEM PUMP TALK

[SmittySX]

I have a 6/12 cutback 7mm that I got from jetmaniac new and have used once that may be for sale soon. I will want full price but it will be no wait. It worked perfectly in a circus with a 727 motor.

Selling the maxx pump by chance?

 

[McDog]

Yep.

Is the 6/12 you used a skat trak prop?

 

[McDog]

Yes. Straight from them through Jetmaniac.

 

[scotts2t]

Yes. Sprightly from them through Jetmaniac.

What did you run for nozzle bore?

 

[McDog]

88 thrust/92 steering.

Shorty cone.

Thanks, I'm going to try this on my 735 when I put 155 in my ski this winter.

I think the smaller motors like the oem 155 without the big hub stator and a stubby cone because it takes the pump longer to pressurize allowing the motor to get into the powerband before the pump loads the motor

I am setting up a ski with OEM 155. PHP760 with PFP. Zach at powerhouse said 5/12 prop, not sure what size nozzles yet. Havent started the build yet.

Managed to grab a 155 pump cheap so looking for some help with props. I am still unsure if this is going to be any good in surf but i'm willing to try. Pump will be going in my new Tigercraft SV-1 running a 61x +5mm crank (810cc) on B pipe, MSD etc. This motor tends to hit later than a SS 61x but once pulling she keeps pulling longer.....So, any advice on props?

@waterfreak
Anyone know if the 155 mm will fit into a Vision 2.0?

 

[N3vrSat1sfied]

The 5/12 worked great for my 760, pfp pipe (which is no standard 760). Running 86/89 nozzles. Might try a little smaller nozzles though

I will be testing a oem 155 with a 6/14 in about 3 weeks.865 with a rrp pipe.lf you can wait,l will give some feedback on it.l am thinking it's gonna be a crap shot at best.

As far as surf,you can't beat a mag pump.

Yes please dude, my new ski will be a while being built anyway.

Could we make a list over what is needed for doing the conversion from a 144 superjet pump to a 155 oem pump and what models that have these oem? It would be to great help for me and others looking for this option

Just a different driveshaft. I sent mine to Jetmaniac for rebuild and shaft.
Then you have to figure out pump bolts. The 155 I have was from a radier 1100 so it bolted to the intake duct. Wear ring isn't threaded. So I just used short bolts and lock nuts.

@cookn makes inserts for wear rings to run stock 144 long pump bolts.

Every one that I know that has put 155 in stock superjet has cut the pump tunnel larger(intake grate area) to accept more flow including grinding open stock 144 pump shoe or installed a 155 pump shoe.
