    buying used yamaha F100 four stroke, need opinions

    Hey guys, as the title suggests, I'm looking at a 5.5mtr ally boat with a 2009 Yamaha F100 on it. I would love any opinions from people who had/have this motor.
    the motor itself has approx 150 hrs on it, so pretty new as far as i'm concerned. one of the issues I've found going through the interweb is that dearlers aren't fantastic with backup service and yamaha don't help either.
    What i'm worried about is that I've read so much negative material that it's starting to put me off the boat, and i'm getting an unbalanced view.
    some of the negatives relate to the carbies and how the fuel delivery system needs to top notch so as to not deliver bad or tainted fuel. the Americans seem to advise to use fuel additives a lot (possibly due to inferior fuels?)
    Anyway would love to hear all opinions before i put my hard earned on the table.
    (on a side note, this is my first boat in 20 years, and I've just finished paying child support after 8 years and i can afford to take the kids fishing again)

    If it's a carby model, I personally would keep looking, a carby 4 stroke is OK, but nothing like an EFI model, regardless of hours, it's an 11 year old motor, not anywhere "near new" in my books.

    pretty sure yours will be EFI
    early 2000's were carb, easy to tell if you have pictures

    Or a photo of the ID plate on the motor.

    I had an 06 F150 that was injected so I'm almost certain it will be efi. It's the lack of hours that may concern some, 15 hours a year on average. I sold the F150 not long after I bought the boat with 300 hours so it's average was 25 hours a year. As far as I know the buyer has had no trouble with it.

    DETL means it is an EFI motor and is NMEA compatible

    Low hours can be good or bad if the boat has been stored in a garage say built on to a house and it has sat for years i see no problem inside garages is usually dry air

    If it sat out in the yard in all weather rain, hail, lots of winter fog etc ss atmosphere temps rise and drop the air around the outside of the engine would penetrate the engine up through the exhaust and rust cylinders, seize engines etc..

    Than u have a engine stored at lets say regional/just out of the city vs sitting 250 meters from the sea on a front lawn

    i googled NMEA and that opened up a pandoras box, at a guess, i take it that real time information is shared between devices connected. I'm going to have a look at the boat tomorrow and if the boat ticks all the boxes, I'll get a local boat mechanic to do a check on it.
