Based on my experience w/ carb and EFI engines, the EFI will get basically
double the fuel mileage given your not running it wide open all the time.

For example - My Baker w/ a 2.5 carb 240 hp engine would get about 2 mpg on
any given day of riding and playing. My Mirage w/ a 2.5 efi 280 hp engine
would get about 4 mpg on any given day of riding and playing. And it was 4
mph faster.

Seen similar results on pontoons I have had.

Huh? Tony, you lost me there.

I have a carbureted Merc 115, and the motor runs great, but it's tough on
the
wife when she is trying to get the boat off the trailer in the morning.
The
engine doesn't like to stay lit unless you know exactly what you are
doing. If
I could change one thing, it would be carbs to EFI.

I wouldn't pass up a great boat with a carb motor, but I do really prefer
EFI.
