Can someone identify this lower unit? How can it be confirmed?

I am use to older (70's and 80's) omc 3 cyinders. This lower unit looks very similar to OMC. It has a 20 spline drive shaft (as opposed to the 4 spline on my OMC) but a 13 spline output shaft that will accept an OMC prop. The shift rod has a kick instead of an offset like my OMC. I had a Suzuki once and I believe the prop on it was the same. The shift rod cover seems to be larger than OMC and it has an exhaust coupling/extension (not shown) of some sort I do not remember seeing. I will post this in Suzuki and OMC forums hoping someone can ID it. I googled some casting #'s off the unit housing and water pump but nothing came up. How can I positivly make an ID it?

sure looks like omc to me,EXCEPT for the shift rod cover.....

So are you saying that OMC has this drive shaft spline and shift rod bend configuration?

 

[jwbmarine]

omc does have a 'fine' and a coarse d shaft spline,cant rem the count....and i am thinking that the shift rod is turned backwards...

i have never touched a 'suzuki',but if i had to make a quick decision ,i'd say omc fr everything i see,and think the skeg,has had some mods.

i agree on the shift rod cvr...just does'nt look right.

Looks like its off a 120/140 looper late 80's to early 90's. Turn the shift rod around 180 degrees and it will be right

No question it's OMC.
