Rough runnin 7.3 idi

My uncles got a 87 f250 with the 7.3 idi with about 450000 miles on it. It was starting then running rough then it would die. It sounded like a fuel issue so I started with the fuel system. I first checked the filter and noticed that the bowl was empty so it wasnt getting any fuel I started checking the lines back I found the problem like there next to the bowl. The feed line was cracked so I changed that and the fuel filter cause it looked dirty and cleaned the bowl out also cause it looked like no one had ever cleaned it before. So that was about a 4 hour job. He also had me do the wheel bearings, and change the diff fliuds which was about anouther six hours

Lube service

the next day after working on that gear i went down to our seiner and full lube oil service for our main engine, gear, and auxillury. the main runs 15w-40 and takes just a little bit under 10 gallons to fill along with one spin on filter which your supposed to fill before installing. i also changed the primary fuel filter on the engine and the two racor filters. They one was fairly dirty and the other wasnt too bad and drianed the bowls to check for water and found none. Then I also cleaned the crankcase breather. Next was the gear on the main. Its a twin disc 514. I did a fliud swap and filter also. All together it was about a six hour job

about two days after that my uncle was moving his seiner around the harbor and all of sudden he lost the ablility to shift so he managed to get it over to the dock and he gave me a call to come look at it. i get down there and the first thing i do is check the oil level in the gear. ( its an 514 twin disk gear too) the oil was not even showin on the dipstick so we started to fill it back up. i added about 3 gallons and but it still wasnt showin up on the stick so then i figured i should check the bottom of the gear and the fittings down there for leaks. but before i could do that i had to get all the water/oil/ whatever else  out of the bilge since it pretty much sat right in it. so after pumping out enough stuff that filled up two 55 gallon drums i was finally able to see the bottom of the gear to inspect it. and the very first thing i saw was the draw for the pump which was a 1/2 inch pipe 90 regualer black steel with about half the side of  it just corroded away. so after getting that off and replacing it with a stainless steel one. we drained the oil changed the filter and reflilled it and ran it for 10 min. then drained it and changed the filter again and filled it and and ran it for about hour then i noticed two of the hoses were leaking so we had to change those out ( none of the fittings or the hoses looked like they had been changed in a very long time). after that we took it for a sea trial and ran it for 5 hours and came back in and changed the oil and filters agian. then did one more sea trail for 8 hours and came back in and changed it it came out looking clean. we will probably end up rebuilding it during the winter after fishing season.
