I'm planning on making a 6 hour drive this week to pick me up a boat that pretty much has everything I want. The guy selling it to me wanted to make sure I knew it was a carburetor Yamaha 40 and not EFI. I actually didn't even know what that meant so I did some googling. How big of deal is that?
Sure EFI is nice, but I've owned at least 40 boat/motor combos in my life and only one was an EFI. Certainly would not be a deal breaker for me. In fact right now I own 3 motors (4hp, 25hp, 40hp) and none are EFI.
I would love to have a carburetor motor. At least I could work on it (I think). Wish my cars were carb as well. GL with your purchase, keep us posted. Make sure you check the bearing and axles before you start your trip home. Might be a good idea to take a grease gun, a jack and tool just in case.
EFI is electronic fuel injection in case you didn't know. EFI is suppose to be better but there is thousands of carb motors out there still running just fine.
4 stroke with carburetors?

EFI is a little easier to operate, turn the key and go. May or may not have a primer.
EFI will have problems too and is often more expensive to fix than carbs. However carbs can be a little bit fiddly and tend to have more problems if neglected.
It's a toss up IMO, not a deciding factor alone on a boat that otherwise meets your needs.
For me, not a deal breaker at all.
Mine is a Mercury 115 2 Stroke 1992 Model.
My advice, especially for carb models: (1) Run a quality fuel stabilizer ALL THE TIME, Mercury Quickare recommends 1 oz per 10 gallons of fuel, and that's what I do. Buy it at Walmart, it's not much. (2) Run that engine at least once every couple of months or so, get it up to temp, and wind it up at least once per outing. I also installed a quality fuel filter/water separator with the clear bottom with drain so you can keep check on it. Oh, and replace fuel lines is a good idea - remember - it's what's going on inside them (That you can't see) that will getcha!
Two or Four stroke, the above may seem like over kill, but it keeps things moving and out of the shop, and it seems to run better and better as the years go by!
