hi. only one imperial is running ok the other is now in pieces and the motor is now repaired and running. the outboard engine number has a 4 on top and below are 2 capital A A then some numers following. i dont know what any of that means so would be intersted to find out what the engine numbers mean as i have about 8 vic 18 engines?

If my collection is complete ( then how come i keep buying stuff ? ) 🤔🤔🤔🤔🤔
