It is the first of the 'purpose-designed' sterndrive engines from Mercury. (250 HP) Prior to that Merc used GM engines. Are you looking at this in terms of a specific boat? I think the engines were introduced in 2014. There is also a 6.2L 350 HP engine.

The Bravo Outdrive has been around since 1988 . . . pretty much bullet proof. Are you looking at Bravo 1, 2, or 3?

EDIT: my bad . . Bravo 3. counter rotating props. good for hole shot and heavier boats . . . Bravo 1 is better for go-fast.
