I just bought one.... it's a 2002 150 EFI "super six"....it has appx 400 hrs on it, has been well maintained, I'm second owner.
So far I love it....I did some research and was surprised to learn that Suzuki has built and sold more outboards worldwide than any other manufacturer. They also pioneered electronic fuel injection and are the only manufacturer that measures hp at the prop instead of the flywheel. So, they're faster....period.
Good luck.
I had this same motor 2001 model on a deck boat. I sold it in 2015 and I’m guessing it had 1200 or more hours on it. About 90 percent of that with a tube behind it. Best combustion engine I’ve ever owned, hands down. Never sputtered and I did virtually no maintainence on it.
