Need help identifying this Mercury Crank
Starting to organize my old parts, and don't remember what crank this is... A little helping hand would be appreciated.
Thanks in advance---

3.0L - I don't see an oil gear in the pictures, could be from an Optimax or newer EFI

I bought it years ago, for project that has languished (I actually have 2.5L and 3L cranks here), so if this one of the 3L cranks this would appear to be a 250 or 300 ProMax... Any way to narrow it further?

The older carb, EFI, Promax Had an oil pump that ran off of a gear on bottom of the crankshaft. The newer stuff has an electronic oil pump so they did away with the gear. I am not sure what the year was that everything switched to electronic. Hope it helps.

That casting # claims to be a 1996 up 200/225/250 3.0 efi crankshaft. So no gear, electronic oil pump in '96 on.
