Keep in mind that I'm comparing it to a 20B water pump, not a = 13B water=20 pump.  The 20B pump (housing & cartridge, no pulley) weighs = 11.8=20 lbs.  The Renesis pump & housing after being cut off the = front=20 cover is 4.5 lbs.  So, I potentially can save over 7 lbs. =  The big=20 question is if the Renesis WP flow is enough water to cool the 20B.=20  

At present, I'm still gathering parts for the conversion, so = I'm=20 currently running the stock 20B pump.
