it has a yam block which is know to be good. It is the same engine as the mariner 80 and 100 which were made until the end of last year. should be a very good engine
I have the Merc 90, year 2000. The Clymer manual says it's the same engine as the one you're looking at, just a different colour. It's a Yamaha engine with Mercury/Mariner leg. It's been well used. No problems at all and still going strong. Absolutely clean under the hood.
