I am using mercruiser power steering mount #806394A1. The used chrome power steering pump that I bought won't align with the crank pulleys

That is correct the spring and pressure relief valve are of higher pressures compared to what GM auto / truck side use for the Saginaw units.. After changing the spring and pressure relief valve, it is very wise to verify the pressures and follow all the testing procedures that is all described in the Merc OEM service manuals. Merc sell the tools to do so. I actually have 2 sets.

I actually started to sell a filter for the low pressure side of the steering system. If you ever took a sample deep down in the corners of the reservoir a lot of times its crud that has settled. Sometimes even corrosion.

Thru out the years Older units were different with the reservoirs and some components. .

Can the correct spring and pressure relief valve be verified visually from the incorrect GM Saginaw parts?
