Can anyone suggest where I could find replacement waterpumps for my 39 mercury flathead? Do I dare trust Napa? I would like to purchase the best quality I can. Keep in mind this is an orginal non rebuilt motor. Just had one seize so I figure I should Replace both while I'm doing it. Thanks
Speedway Motors has real nice water pumps. They have the modern seals and bearings in them. They are new and not rebuilt.
speedway is good. be careful when you remove the bolts inside of the water pumps. i had the heads bust off on both of mine!!
Go to Bob Drake or Dennis Carpenter. They both have new design pumps for $130.00/pair. Check their websites. Murph
