As was stated, if you want to know the current 4 banger, pull the prop and look on the hub.
My 1990 190 with powerslot trans has a ACME 4blade 14x20. Top Speed right at 50mph. I'm not sure what would have been installed from the factory.
I do have an additional 3 blade that came with the boat but I'm not sure of the size. The dealer that I boat the boat from said that they installed the new 4 blade because the boat was turning 5600rpms with the 3 blade. I have yet to run the prop to confirm rpms and speed.
