engine replacement-gctid381128

Turns out the replacement engine probably has around 800 hours on it. Seems like that might be a little high. What do you think? I think I can get it for around 800 bucks. Again, it is a complete engine. He will run it and do a compression check for me.

Do the two motors have the same carburetor connections for fuel and throttle linkage? Both have electric fuel pumps?

With the 5.7 you're likely going to be a little underpropped, but it's certainly no showstopper.

I have water in my oil on my 98 merc 5.0 in my 2355. I was planning on tearing it down and fixing but just got a lead on a good price for a complete 97 merc 260. Will this mate up with my current outdrive/bell housing (alpha 1 gen 2)? Is there anything special I would need to do or can I just unbolt everything and pull it out with a fork lift and drop in the new?

Thanks,

I assume the 97 is a 5.7. It's basically a direct swap - the 5.0 and 5.7 are basically the same engine save for displacement, and gearing stays the same. If it's a 5.0 MPI, also 260hp, there'd be more work - but it'd e well worth it.
