First generation number IIIs and number IIs were non cresent I believe it wasn't until about late 70s early 80s that the cresent lower came out. The 35 Cigarette race boat I have at the shop is non cresent its a 76 model and I have a set of drives off of a 41 attack that I believe is an 81 model they are also non's Regards Dan

Ok so I was able to measure the bolt holes and the lowest hole on the outside is 7-1/2 " from the bottom of the hull to the centerline of the hole. My drives are on 36" centers. So I used some measurements from another 36 with SSMIII and my math says my x dimension is approximately 5-1/2" .
If if anyone here has a way to confirm that it would be appreciated.

x dimension and drive height are two different things. x dimension is the point from the bottom of the hull to where the upper shaft goes thru in a straight vertical line. drive height is where the propshaft is from the bottom with the propshaft parallel to the bottom. if you have no spacers in the drive, if you tell us the drive height we can look up and see what the x dimension is right now.

Does anyone have a schematic of the these drives mounted on a transom with dimensions? I saw one a while back but I can't seem to find it.
Compedgemarine---- Thanks for the information. I always thought the x dimension was from the bottom of the hull to center line of the prop....glad to be set straight and I never thought of the drive mounting height VS the X dimension. I just thought in my case they are not exclusive as there are no shorter lowers or spacers available as far as I am aware.
