:)Hi everyone; I've 2 mercury 20hp engines (I believe they are both blue band engines but not 100% sure). The engine numbers are 2893122 and 9122768, I believe the years are 1970 and 1986 again not 100% sure. Could anyone please let me know the correct years for these engine so I can then press on with my next question being are the lower units compatible.
Thanks for your time
