Default Is this Suzuki 90 toast?

I am looking at a pontoon boat with a Suzuki 90 four stroke engine. I had a data dump performed. The engine has only 60 hours on it, but the oil change reminder has triggered twice. It shows zero hours since the reminder was cancelled. My understanding is the reminder should have triggered at 20 hours, and then again at 100 hours. This looks like the oil was not changed. The boat was bought at auction by the dealership who is reselling it. Should I run from this engine?

Also, my understanding is the warranty will not transfer if the engine was sold at auction. Is this true?

I know boats are a different animal but I am old enough to remember reading change the oil every 15,000 miles or one year in my 1981 Toyota pickup owners manual. That truck went over 200,000 with that oil change schedule and it had one of those high compression 4 cyclinder engines. I change my oil every spring and it still looks more or less new on my 2000 Evin/Suzuki 70. An engine does not magically stop running if the oil gets old. It just wears harder and faster. Get the compression check. If good, then you are good.

how do you know the oil was not changed , re setting the oil change warning is easy and so is dropping the oil and changing the filter..
chances are the oil was changed and just looks old because the motor needs a good rev(carbon / unburned fuel ).
oil reminder will intermittently trigger till the re set has been performed ,so if it is not squawking at you now someone has re set the warning.
motor should be fine even if the oil is old , good practice would be an oil change directly after purchase anyway.
good luck with your new boat "enjoy , those little motors are indestructible.. .

The engine may be toast.

The engine probably is perfectly fine.

You can’t tell either by an oil change reset that wasn’t done.

I’d be more concerned about the events leading it to auction than running it 60 hours without anyone resetting the oil change warning though.

I can't tell if the oil has been changed. Had it been changed at 20 hours, there would have been no need for the second alert that was just cancelled zero hours ago. The second alert should have been at around 100 hours.

the auction people may have re set the warning so as not to disturb potential buyers, or so as bidding will be inline with the reflective hours.
regardless, 60 hours on original oil is not the end of the world.
as posted i would be more concerned as to why it is at auction with so little hours.

if it starts and runs and the deal is right, I would have no issue with it. I know guys that have hundreds of hours and only have changed the filter and added oil.
I would be more concerned with it showing running hot too many times.

The engine is not testing the oil to give the warnings. You could contact a Suzuki dealer to find out what conditions would cause the software to give an oil change light at 60 hours, but I don't think the answer is going to help you know whether the motor is toast, it's just going to help you understand what might or might not have been done by the previous owner regarding an oil change reset.
