Has anyone ever done it? It sounds like a decent winter project for me, and I'm looking for anyone who has tackled it. I've owned a boat with MPI's in it before and I miss how well they run. Current boats carbs are getting old. I thought I would do one motor at a time. That way I could compare the two, then decide if I want to do the same to the other side. I would try to find a complete used Merc system for the retro. So, I'm looking for success or horror stories of a similar deal.

Thanks,

Steve

For all the work, I would go EFI, Yes I can help

A buddy of mine is taking off TWO MPI fuel injection set ups, they are on 502's . He will be selling them soon.

if he would split them up I would be interested in one of them providing the price was right let me know

Exursion,

I may be interested in them. I'm working on a deal for one set up now. If it falls through?

Still hoping to hear from someone who has actually done this.

Does anyone know from experiance the amount of increased fuel economy?

Wouldn't Tyler Crockett's new EFI work for a retro fit? Then you would also get another 30 HP. Try tomcall him. He is also on this board. I think it was last week he let us know about his new project. Might want to search his name.

My father has one complete Merc MPI set-up if you are interested.

If it is a complete set up please PM me with the details.

I have a friend who is considering going carbed on his Fountain. So he may have 2 complete set ups for 502 for sale. If interested let me know and I can get more info.
