Devil in the details

I stopped by the NAPA web site to look at the water pump for my D30. They offer 3 variations of the same pump. Two new and one remanufactured. In the individual item description I find pump rotation: clockwise, counter clockwise and standard.

So when did they reverse the rotation of the crank in these flathead sixes. I'm guessing the "standard" works both ways.

Maybe in the old twin marine inboard applications, counter-rotating motors?

I know there is a internal and external water pump by pass never heard of different rotations. Here is the NAPA # from the parts reference on this web site 55-713 see if they can match the number

That is the "clockwise" pump they offer. The remanufactured one is listed as "counter clockwise".
