The two are basically the same configuration, but the 1047 is considered suitable for marine use because it has a stainless steel core. Both have the 4.54 bore. The 1017-1 and 1047 are .039 thick, the 1017-2 is .051 thick. The 1017 has two coolant holes per end, the 1047 only one. Either will work on your block just fine.
