    1976 Evinrude - Metal vs. plastic water pump housing?

    Good info, thanks! The old style water pump is unobtanium and the new plastic/stainless unit is pretty pricey if it won't solve any issues. I had some free time today and decided to drop the lower unit and check out how the water flows through the system, and y'all are right, the intakes are...
