I need to change a fuel pump on a '93 Merc 175 EFI. I am very mechanicly capable of doing the work but I have never worked on an outboard this big or an EFI. Can someone give some info on changing this. Also is there a place online to download a Service manual for changing the pump...So I know exactly where everything is located. It does have the auto-oiler, can I bypass the oiler by just plugging it? Thanks for any help. :-/

You can get the CD on e-bay.

Any ideas on the auto-oiler.....also is there two pumps on this engine?

Found what I needed.....must not be many Mercury folks on the board, if you have any questions send me an PM I now have a book.

There are lots of us on here we are just smart enough not to try to fix them. Good luck

Well....I've saved a lot of money asking questions and being "dumb". fishfordollars, I think your selling yourself short....There's nothing....let me repeat, nothing anybody else does that someone else can't learn to do.

Might be me then. Every time I try to save and work on my mercury it ends up costing me more for them to fix what I messed up.
