These valve covers are not only the most beautiful addition to any Big Block Chevrolet marine engine they also solve one of the most difficult and annoying tasks for power boaters, inspection and adjustment of your engines valve train! Sold in Pairs for one engine.

A positive o-ring seal assures a leak free seal between the covers and receiver rail, but best of all the cover is removed via two integrated thumb screws. That’s right no tools required here. The cover can be removed and replace in just minutes. Allowing more time for what you want to do most — powerboating.

NOTE 1: You should tighten the valve cover rail to head at 130/120 in lbs. and the wing nuts to 25/20 ft lbs.

3 Stage Stainless Steel Sea Pump

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.
