i don't have a problem with the mechanical part, I'm pretty mechanically inclined, herd there pretty bullet proof as long as u keep an eye on ur oil for the outdrives !
Get the exact engine and outdrive model and serial numbers and start looking for wearable/maintenance items for both.
Not a truck 460 alternater, a marine alternator or a starter for the marinized Ford 460
Exhaust manifolds/elbows and cooling risers
Thru hull gaskets for the outdrive
Impeller for the outdrive
etc etc etc
The boat's nearly 30yrs old, you and your buddy know the last year's history on the boat, motor and outdrive. I wouldn't rely solely on the hope that my own diligent maintenance will keep it running and running right long term. Boat drivelines are under a different load then a similar motor in a truck.
And stuff just happens.
When it does can you find the part you need, at a price you're willing to pay, and how long will it take to get to you? Probably not going to find all the wear items at the closest marine store.
FYI: I don't have any idea whether the advice to
keep an eye on the gear oil is accurate or if that makes them
bullet proof, I don't own a Ford/OMC I/O. I also am not trying to talk you out of buying the boat, it's all just info I think you may not have or considered.
I would hope a friend wouldn't deliberately sell you a boat that wasn't worth whatever you agree to pay. I suspect the friendship at risk comment was based on how sideways an older driveline, that longer has good parts support for either the engine or the outdrive, could go, because like I said, stuff happens. Seems to more frequently w/ boats and friends that buy/sell or own boats together.
