Title: Water pump
Post by: goatracer on February 28, 2019, 08:39:12 PM

I have been having a running hit problem and decided to check the water pump tonite   This is what I found    Would the difference in the cavity area restrict flow ?

looks like the cavity in the aftermarket cover was not milled enough (in length) to make sure that no restrictions exist.

I checked a few of my aftermarket water pump covers....all matched up with the separator plate like the oem does. What pump cover is that?

That’s odd. I thought Merrill made good parts?

Merrill does make good parts....Just like everybody else in this industry things go wrong from time to time.....I have a 370 with a Merrill water pump cover on it with zero overheating issues and that's after two full seasons of racing....
