It also helps knowing it’s a 1992 year model which is listed in the serial number range too linked above as 92 was more consistent of being in the 0B/0C range so using 0C and the number we’re able to make out is the only Bravo unit option that pops up in any known combination…It’s just odd that it only comes up as Bravo and no other info beside it as usually it will say B1,2,3 and gear ratio when it’s actually a drive… without the extra info generally means it’s a Transom assembly housing number…. That or the drive was replaced by Merc for a certain cause by a representative for a manufacturer and never got recorded properly which they did often back then when testing, etc..
But the 0C is enough to use to look up parts in the Bam Marine website as 0C834565 comes up as/with the following parts catalog,
BRAVO DRIVES - 0B664190 THRU 0F729999
