Is it closed (freshwater) cooled?
If not then I could see maybe needing manifolds, exhaust at least.
Have you priced complete drop in replacements that you are considering?
Such as the 6.2

Go for the 496 Bravo. Closed cooling, Smartcraft, forged crank, warranty.

Lot's of happy 496 owners out there, lots of support, parts, expertise.

Give these guys a try. A buddy of mine is a career marine mechanic and his west coast florida shops used to source from here exclusively. He recommended them for both remanufactured and new engines.

Well that's good to know as the engines are out of mine receiving a transom and i was considering doing the couplers at 323 hrs. and 25 years of age. They're greased yearly, splines show no signs of misalignment and mechanic didn't note any anomalies. Sweet $2,000 part savings and I need it the way this project is going haha.
