No template, but A few years ago when I did a transom I picked this up for drilling the holes, set it for 90 degrees and your holes are perfectly aligned. Handy little tool to have around.

dimension between upper and lower shafts is the same for STANDARD length alphas (gen 1 and 2), pre-alphas and bravos. alpha ss and bravo shorties are shorter to raise prop shaft height. TRS is longer. shift bracket on exhaust. can alpha be used for bravo?

i went the cheap route and just bought a small section of plumbing pipe a little bit bigger then the drill bit and then threaded the pipe onto a threaded flange...dont have any pics but i found this on the net.
