I'm looking at putting a different 175 Merc on my Hydrostream Valero. Currently have "antique" Black Max 1750 with some hairline cracks in 2 cylinders, have the option to re-power with a 92 or 93 175 EFI that's on a big Lund fishing boat. (Compression and leak down test comes out great and even.)
Question, then: Would lower unit final gears be the same on this Merc as other 175 EFIs? Is there a difference in gearing- one setup for power, another for torque, another for top end speed, etc.? If so, how does one determine the difference or type of motor by serial number? (I have a pretty good understanding of propping.) Thanks in advance for any help!
