Does anyone have the info or a good link on what the exact sizes of all three (Alt, Water and main) belts are for the Yanmar3gm30f?

I have only two belts on my 3GM30F. The shop parts manual lists these:
Alternator: A 36 inch V-belt; Part #121150-42290
Raw water pump: M 19 inch V-belt; Part #104511-78780
A Gates belt or equivalent quality from an autoparts store would be much cheaper than those from the factory. I found it best to take the old belt to the store for a direct replacement size instead of guessing.

I would say that you have an A/C compressor that's not standard for the original engine. I like Dan's idea about just removing the belts and taking them to a parts store that sells gates belts. just my 2 cents worth.
Here's...
the front view of the standard installation...
Looks like a GM AC compressor from the partial view...

Makes sense as I do have a frost box that runs off the engine - will measure and go to auto parts store - just want spares to be safe.
