These pumps have the following part numbers
PUMP ASSEMBLY
90507A12
16792A40
Google search gives me either part number and always picture of left pump.
My 1997 Mercruiser 3.0LX has pump shown on the right.
What are part numbers for pumps shown?
Service Manual #13 advises to install 37in power steering pump belt (p/n 65607T). It doesn't fit with my pump. I was able to install 37.5in (Goodyear Gatorback v-belt 15382)
