To help muddy the water, this particular motor uses the same seal as the earlier 35hp motors.
So my guess is that it is a 35hp block that was bumped up in hp in other ways before the redesign in 1962 to the larger crank/seal.
I looked and now realize that on my website, I forgot to list this 40 under the 18-35 seal puller info.
I will correct that error this evening.
The other question I have is… It looks like there is not a seal installed in the photo provided, or are my eyes getting that bad?
I do not have one of these motors so I have no frame of reference as to the depth of the seal pocket before or after a seal is involved.
