3 Stage Stainless Steel Sea Pump with 1 Groove Pulley, Single 1-1/4” NPT Front Inlet & Single 1” NPT / 1-1/4 NPT Rear Exit Common

Our 3 stage Extreme sea pump is unsurpassed in the marine industry and is the number one choice of the most recognized engine builders and offshore racers in the world today!

Designed to incorporate the same features and the single and dual stage pumps, the addition of one more impeller allows for maximum water flow to be passed through the engine while the third impeller is dedicated to cooling the intercooler only. Dyno testing has shown that dedicating an individual water flow thru the intercooler does indeed increase horsepower. The triple stage Extreme pump allows you to accomplish this without sacrificing valuable cooling water in the engine itself. This pump is custom configured to your individual needs.
