The rebuild of my late Merc flathead engine is being held up by inability to get a proper new waterpumps. My new waterpumps obviously must be properly rebuilt for improved flow. My engine will have a single narrow Vee belt accommodating an alternator and likely more ,I'm not aware of.

Here's the rub, the pump rebuild house, who I trust, can't seem to get a proper pair of Merc pumps to work with which have the right wheel diameter, shaft offset, and belt dimensions. The last 3 orders he received were wrong - wheel dia, belt size, offset, etc.

In the chance someone here knows a better source of Mercury pumps than my guy, what say you?
