If you are interested in fuel economy do not use a Holley

Now, I wonder how much a street rodder will give for my MPI?

Go with an Edelbrock Marine 750 with an electric choke. That combo will give you good performance and fuel mileage. The Edelbrocks are easy to tune. The standard jetting should be very close to what you will need, maybe even a little too rich but, that is a good place to start. My '93 7.4L with a Weber (Edelbrock) 750 runs exellent and gets about 2.5mpg average. Good luck.

dont know what your fuel econamy is now but I run a 1995 23 foot wellcraft that is about 4500-5000 pounds loaded I only run it WOT and have it a little over proped for that reson and get over 2 mpg with it and it has the 650 weber (like edlebrock or carter) hope this helps? Charlie

I`ve never actually checked my MPG, but comparing gallons burned per running time (hours), this Baja uses about the same amount of fuel as my last boat, a 19' with 350-4 bbl.
I just feel like I have a more efficient hull along with a under-utilized engine (at cruise) than my previous boat.
The carb idea came about after realizing all the tinkering needed to add any power to this fuel injected engine. I believe I would be making a good decision to swap. If I can sell the MPI for a fair price, the swap would practically be free!

Unless you have closed cooling or only boat in fresh water don't use an aluminum manifold or make sure you have it coated before installing it.
