I have a Johnson Pump F7B-9 (10-24394-1). A raw water pump for my Volvo
.. It has two 'lip seals' in it. Which way do they go in? I wasn't there
when they took them out.


Any ideas??

If I was you I would ask either the counterman at a parts house, or
most any mechanic.

The rule is the pressure side is on the spring side allowing the pressure
difference to add sealing force on the lip.

In a comparable situation with an inboard/outboard, I noticed the lip
seals were arranged to close the lip in the direction of greater
pressure, or undesired liquid flow.
But I have seen advice that where there is space for several stacked
lip seals, one could place at least one facing both possible flow
directions.

I would go to jabscoshop.

You will find a complete exploded diagram of your pump there.

I think it is in the Dr Watson section.

p.s jabsco and johnson pumps use the same parts.
