800 hours on an 1987 Onan genset. Rebuild engine?

My 1987 Onan 6700 watt/50amp genset shows just shy of 800 hours use. Nothing's wrong with it so far, just wondering how many hours of use I can expect, before it's going to need a engine rebuild. I know that's subjective to how it's been maintained in the past.

    10,000hours on gas genset is a lot of hours. 800 is nothing.

    at 800 hours assuming reasonable maintenance, your genset is hardly broken in. you will more likely have issues from lack of use long before you wear it out. You need to run it 2 hours a month under load. This keeps everything lubes and pliable Seals don't take a set etc.
