805HD, I just read back through all of your threads.
While this may wrinkle the feathers of the Merc aficionados (and no offense intended), why don't you consider doing this:
1.... abandon the use of the A seawater pump.
You will still need to keep it active as it provides A drive upper unit cooling. You can route this water over-board.
2..... install a thru-hull pick up system.
3..... install a crankshaft pump if you have the necessary space in front of the harmonic balancer.
This would at least eliminate the potential issue of not enough seawater from the A drive seawater pump!
4..... if you cannot install a crankshaft pump, go with the Merc style belt driven seawater pump.
Either the crankshaft pump or the Merc belt driven pump will provide more seawater than what the A drive pump is capable of.
