I've looked this question up on the internet and get different answers. This is not a 400 or 800 model but is before that. It's hooked to a OMC stringer outdrive (don't ask). Can anyone help me with this?
Thanks for the info about the 305. There's no plate on the valve covers so the guy I bought it from must have been wrong. I couldn't find an OMC 350 for that year either.
