Belt on 3YM30AE Yanmar

Can someone who has a 3YM30AE let me know what the specs are on the serpentine belt. I need this to spec the pulley on an alternator which will replace the Hitachi.

Also any recommendations on who sells good belts which are cheaper (and better?) than the Yanmar belts?

No, i'm sorry...

But i'm planning to buy a boat/repower it with this engine...

How is yours?
Faulty alternator? or you just want bigger?
How many hours?
Problem?

Thanks
Stefano

stefano,

I don't currently have the engine as we are re-powering like you are. The 3YM30AE is the upgrade for us (from the 3GMD).

I want to have a second alternator on board and definitely want externally regulated (which the standard Hitachi isn't), so need to know the pully/belt sizing.
