Can someone de- code this Bravo1 Drive.,Supposedly a 1998 Bravo1/ 1;50 ratio
OF 453793.

Thanks

My 1997 Bravo drives and transoms are OK xxxxxx so the OF's will be older.

Thanks Griff, how much older, like maybe mid 1990's, it came off a 1998 Baja, original boat owner says he didn't change it till now.

That comes up as a 1994 3.0LX engine, are you sure of the number?

and if that was for a 3.0L - 4 banger - the gear ratio would not be 1.50 either.

BAM are you around today - I would like to call you about something. Thanks John

No not sure, seller says numbers are hard to read, says it could be an OL code., I'm gonna look at it Monday, upper tooth count is 1;50

Thanks

Using 0L453793 would make it a early model 1998 MERCRUISER PERFORMANCE DRIVE BRAVO 1, 1.50:1R model number 5C31200LS. http://www.boats.net/parts/search/Me...0LS/parts.html

Thanks for all the help,
I have a lot of pics of the drive & internal parts, definitely a Bravo1 , 1;50 ratio upper gear tooth count, thin floor gears , looks good , the upper bearing went bad so the owner bought a rebuilt unit , will know more More after I see it.

OK, I inspected the Bravo1 today, it ,,OL,, Code, stamped very lightly and hard to see , used a magnifying glass to figure it out,, looks real good overall so I'm gonna install all new bearings/seals, etc. on upper & lower.
Thanks for all the Tech. help & info.
