Selling my hardin dual stage pumps. They were purchased brand new from Hardin just a few months ago. Have maybe 3 hours of fresh water use on them and absolutely no damage . They include the the large Y pipe manifold and 90 degree fitting on the inlet side. You will need your own 1" NPT fittings on the exit size to fit your setup. These were 950.00 each with the stainless 90. Price is 750 each

With or without fuel pump mounting pad?

Are these still for sale

I sold them but the guy I sold the too is on Facebook as melroy Daniel. He listed them for sale right after he bought them same price I believe

Why did you take these off? I was thinking of running them on 700's with the 2nd stage going to the intercooler for more flow?

I didnt think they were getting enough supply from one single through hull so I switched back to force feeding chillers through the through hulls and engines from the drives and standard sea pumps

Thank you I appreciate that! I think I'll just leave the stock system the way it is and do the whipple re-route, T just after sea water pump to intercoolers. Then monitor pressure over 4100rpm via smartcraft data. If higher pressures like 35 to 40, then leave as is. If lower than 30psi, maybe think about adding a second dedicated force fed pickup and sea strainer for each intercooler.

I work on same problem at moment with an SCi engine.What Lower did you use???
I want to change to an Sportmaster Lower now and think this one will make enough water for an Stage 2 Pumpe!!??
Also Try to reroute water for IC and have mount the bigger inlets like whipple sell!
I have option to take out the restrictors (partnummber 8) from silent choise diverters if waterpressure go to high.There are only small holes (9,5 and 10,5mm) at moment ,so i can drill them bigger if need!!
Any suggenstions?
I want to buy this stage 2 pump now! Michael
