TOPIC: 1965-75 Mercruiser 120/140 shop manual?????

Friends,

I've aquired a complete (with all the dealer-installed "appearance goodies"/chrome) 1969 vintage SternCraft Balboa on a NICE trailer that is missing the entire engine (it froze & burst) and therefore am seeking a shop manual to replace the whole engine/outdrive with a similar vintage system.

NO, i'm not interested in changing to a modern engine/outdrive, as i'll be restoring the boat to "as new" eventually.

yours, satx
