Difference between OMC 200 & 225 Looper?

[Robert1050]

Now that it looks like I"m going to be re-powering my boat, I do have a couple of options. I feel kinda dumb asking, but aside from the obvious 25HP difference, what other differences are there on a mid-90s 200 & 225 Looper? I have searched every site I can think of and am not finding much info.
Thanks,
Robert
