Default Low-time early 2000's yamaha 150's-great or run away?

Have an opportunity to pick up a hull that I'm a big fan of, good condition. Boat originally had a pair of 1989 yamaha 200 v6's, was repowered to four stroke yamaha 150's circa 2005 or 6. Potential seller claims only approx. 60 hours on the "new" pair of motors. Sounds great, but that's like 4 hours a year and concerns me a little bit. Most of my experience with problem outboards tells me that most of the problems were the result, at least in large part, of not being used. I have no experience with the yamaha 150's from that time period, but for some reason I am thinking they were not part of the dry exhaust corrosion issue that took place around that same time with the...250's?

Anyway, interested to hear from anybody that's got much experience with that generation of yamaha 4s 150, and how I should feel about the hours.

Depends on how they have been maintained? Annual service or no service? Those years had the balancer issues and may eventually have exhaust corrosion but that is quite rare on the 150s.

I dont have the full picture yet on the maintenance, am prepared to be disappointed as I have to wonder how much thought was given to maintenance when they only managed 4 hours a year of run time. Or worse maybe its had a couple 20 hour years and several years of no time.

I have read about the balancer issue, but that seems like it might be an issue a guy could get ahead of by taking care of it proactively.

I have a set of 05's with 2000hrs on them..
No issues other than cleaning the injectors a few times and doing the VST tank rebuilds 2 years ago...
Just ran 150 mile trip on them last Saturday....
