Electronic Fuel Injection vs carburetor on 9.9

[nate01]

This is for use in fresh water only, and I've had problems with used small motors in the past so I am buying new...so 4-stroke is the only option.

I guess what I'm struggling with is the advantage of having a lighter, more simple carbureted engine that would be cheaper to repair vs having something that is clearly a technological advancement that is arguably less likely to need adjustments etc. Given I'm not mechanically inclined, and lazy, that is a big plus for me. Keep in mind I'm not running this thing every day or even every week, and there will long periods of time it sits in my garage. My old carbureted 5hp didn't react very well to month old gas etc.
