My (new to me) drives do not have serial #s printed in the stripe on the units. I am trying to determine if there is a serial # stamped somewhere so I can identify the lower unit and then figure out how to check/service the drive oil.
My last set of Bravo drives had the drain plug behind the prop and a fill on the top side and a dipstick on top. My current ones have a Hardin Sport Tech Outdrive Cooling Shower on top and I did not want to introduce any more variables by removing/loosening it to see if there was a dip stick underneath.
THANKS!

Isn't there a drive lube bottle mounted on the transom in the engine bay ? post a pic of the lower

My last boat did not have a transom mounted drive lube bottle...I will look for one on this boat.
Lower unit attached.
THANKS for the quick response!

There is no dipstick. The drive lube reservoir tells you if they are full

No drive lube reservoir on the transom that I can see.

looks like a standard swept back B-1, drain plug will be behind the prop

it could be mounted on the engine ?? what engines are in it

Redone motors (before I owned her)...489's
Can you see anything...

And is there a top vent screw and/or dip stick (under my drive shower)?

Found it...I was just looking from the wrong angle...
