as ferm mentioned in 1981 the 200 was a vertical reed 2.4L motor without fingerports and 175 was a 2.0L with the big open exhaust. The 1981 v200 is very close to the same power of the mid 80's 175 . . . it just doesn't have fingerports. So the mid 80's 175 is actually a bit stronger if run it with a 200 exhaust tuner.
This is the combo I run on my boat and it's really really fuel efficient . . . not that we'll be thinking about that with Gas back down to $1.60
This is my cruise with a mid 80's 2.4L 175 powerhead on 200 mid section pushing 23 seacraft. Performance was almost identical with the v200 powerhead.
