Re-jetting assist

[shawn30]

Does anyone have access to a 1981 OMC service manual? I’m trying to see what main jet options they offered for 15hp outboards. Does anyone know if main jet from other OMC carburetors fit the 15hp?

I’m at 6000 feet and need to lean my mixture out

Thanks

So I found the part numbers on this site for those who are interested in the future. The 15hp are 5/16 24 thread
