There have been several threads on this subject here that I studied before deciding how to diagnose, repair or replace the air compressor on the port 8V71Ti. I gave serious consideration to the widely suggested solution of removing it and simply plumbing in a small compressor that would run off the boat's AC power. On my boat it only supplies the air horn as the wipers have been upgraded to 12v units. I rarely if ever use air tools for mechanical work and with 2 gens and 2 mains, it's only a 25% chance that I'd need to use them on the port engine which makes the air so I decided this system works for me. I can always carry a pancake compressor on board and use as needed.
I ended up simply replacing the old compressor with a reman unit and I thought that what I have learned may help others who want to keep their systems original as well. I thought it was a Detrit part and called the dealer with my serial number. They told me that my engine did not leave the factory with a compressor and therefore it was not a Detroit part. Other posts here suggested it was a Bendix, and after calling them and looking at diagrams via internet and fax, it sure is. The problem is that the style is a Tu Flo 500, part number 280962 which is old and no longer in production so finding a new one is nearly impossible and finding a reman is not easy. I didn;t have time to have mine rebuilt, so at Bendix' suggestion I got a Tu Flo 501, which is the newer version of the old one. Slightly different port locations, but mostly the same and it went on this morning with no trouble. There are two Tu Flo 501's that will fit our application, part numbers 286540 (the one I got locally yesterday) and 286615. THey produce 12cfm and there are other part numbers that will fit and produce more air ifneeded. I opted to replace with what was there and now my horn is nice and loud again!
Hopefully this will save someone some headache some day and know that these compressors are readily availabe at any heavy duty truck parts place for around $250.
