Yanmar 3GM30F OEM crank pulley size....

I am away from my boat (1.5hrs) and need to know crank pulley diameter to peaks of "v".
Trying to source right size alternator pulley for correct ratio.
It would be much appreciated as I can't find it on the net.

Re: Yanmar 3GM30F OEM crank pulley size....

The picture is from my factory manual. It shows the radius as 74mm or 2.91 inches. Diameter would be 148mm or 5.82 inches.

My engine is backwards since it's a vdrive. I would have to empty a cockpit locker to measure. If someone else doesn't verify the pictured measurement I would do so if you wish.

Brilliant! Thankyou.
I scaled a pic of mine in illustrator with something I knew the dimensions of
and I came up with 150mm so all good.
