Merc 2.5L on Seafari?

[McGillicuddy]

Thanks Bigshrimpin,
You've opened up the proverbial box so here are a few more questions.

Can I assume an '88 175hp would be a chrome bored 2.4L and be of reasonable weight? And is the chromed bore an advantage or disadvantage.

Also what is the 2.0L designation, is that the standard black max 150 or the inline 6 variety, or something else and how do I tell them apart? And what's the weight of the 2.0L.?

What should I expect/be willing to pay for these older motors?
