I have instant starts, great throttle response, and a solid idle in gear or not. I can't say that for the engine that still has the carb on it.

The cool part is being able to run twin engines with one carbed and the other EFI. According to the floscan, the injected motor is burning 16gph at cruise and the carbed unit is burning 20 gph. That's huge! I was hoping for maybe 10%.

If you shop around you can find a complete used set up for less than a grand. I paid a mechanic to do the actual install because I can't crawl around on the engines like I used to. I did do the final electrical and fuel connections though.

I am very happy with the results, and I would highly recomend it. We just started converting the other side lastnight. Hopefully it will go as smoothly as the first one.

Wow, I bet you get some head scratches when you pop your hatch. :eek: Do you have to give one more throtle than the other? Does one pull more RPM than the other at WOT? I assume you will be looking for a deal on another setup. I converted from a carb to MPI about 4 years ago. I like the easy starts and better performance. It made the boat much quicker but only about 1MPH gain in speed.
