I have searched and have not found a chart or list to determine which Lower Unit I have on my 1999 225 Optimax.
I thought I found it when I looked at the Gear Housing Chart but that did not work either.
Can you tell me where I can find a list or chart telling me which Lower Unit I have?

Parts Catalog is the best place to start. Your engine had a Standard/Servicemaster gearcase, 20" 1.75 Ratio.
The latest part number for that case is 859399T13
