What ive been told is that I have a Bravo One X drive with speedmaster lower unit. I cant find any identification numbers ore any other digits on the drive to clearify this, just the IMCO and Mercruiser logos.
There is IMCO hydraulic steering with extentionbox on my boat. Drive shower and Bravo 1 26” propeller.

Is there anyone that can look at the pictures and tell me what drive and lower unit it is?

It looks more like a sport master lower , speed master are #3,4,5 drives............the sport master skeg is longer than the IMCO sc

Here is a better picture of the drive and lower unit. Thanks!

thats a sport master lower and a IMCO back cap for the steering

Thanks for the help!
Do you know how much oil the bravo one X and sport master holds together?
I am considering buying the Mercruiser race gear lube 85w90. Any thoughts?

The upper could be an X or XR from what I've seen, they use the same retaining nut.

Im guessing 2.5 - 3 quarts depending on the size of the reservoir bottle, could be a little more

Looks like the bigger xr style u joints in that first pic

What u joints do you mean?

Hard to see the difference between the X and XR

Thank you!
