Reply To: johnson/evinrude V4 60HP CYL HEAD DIFFERENCES

[Don]

I’m thinking Frank is correct. The pistons are the same part numbers, as are the head gaskets. The hp went up to 65 in 1968 when the part numbers changed. It appears as though the carbs are the same, even though I could not find part numbers for the complete assemblies. High speed jets, carb body, and nozzles are the same part numbers. So, I’m thinking that using the 65hp heads on the 60hp engines would be OK, provided you replaced both heads so the compression is even on both banks….
Let’s see what Frank thinks about it….
