Timing belt change

[MarineBob]

I got a recommendation to change out the timing belt and associated tensioner(s). This is on a 2013 Yammie F250 with about 650-700 hours. Not sure if its ever been done. I got the boat used 5+ years ago with about 300 hours and there is not indication it was ever done. Is this a necessary change? Seems logical but I am not real familiar with this part of the Yamaha.

The recommended timing bely maintenance for my F200s is, Inspect every 100 yours, Replace at 1000 hours. of course that assumes normal wear.( no serious cracking, missing belt 'teeth', excessive rubber dust buildup, no obvious idler bearing issues etc.)

Thanks for the input. I looked on line and found a note that says every 1000 hrs or five years. I know at best its been at least 5-6 years and possibly never so I guess its time. The labor charge is ...well....ridiculous. You can buy the belt for $70 and I suppose a few $$$$ more for the other parts. I guess there is an idler and a tensioner that go with the service, That makes sense while its apart
