I'm on my second as well (new boat).
I have a 140 Suzuki EFI on my new boat and love it. It is so quite that they actually had to add a stall indicator in the event the motor stalls.
I have also had a 40 Yamaha and have nothing bad to say about those either. I don't use very much fuel in either one. The nice part about efi (on both the Yamaha and Suzuki) no choke. Turn the key, fire it up. Every time. No cranking, no pulling, nothing.
Like others have said, they have come a long way in advancements since the first ones came out that were heavier and the HP ratings were not like the 2 strokes. I'll never own another 2 stroke
