Re: 1997 mercury 200hp off shore reliable?
Are you thinking High Performance offshore? The production offshore and blue water or pretty much tha same thing. Both are supposedly salt water motors. Both completly different from tha hot rod offshore (never could figure out why they call it offshore) if thats what your thinking? The production offshore has tha same mid, adapter plate's, powerhead and trim as tha blue water, just an older version.......
Humm, you're right I was thinking the hot rod offshore with the offshore mid, etc. I've got a 99 blue water 200 and if it's the same as the basic OffShore then there's no real difference that I can see. I think it's a good motor if there's no corrosion. From my experience, the hidden corrosion is going to be on top of decks (around the cylinders), the exhaust chest and the exhaust plate.
With 345 hours on it, that's getting towards the end of life cycle on a Salty. If it's been maintained as well as it seems though, it might go to 500 or more. If it was a hot rod OffShore I be jumping on it but if it's just a renamed salty then maybe not.
