Motor Length / Transom Length

[Fr. Frank]

Perhaps a 30" transom was an option back then?

Must have been, for twin 25" shaft motors.

I know the first regular 30" shaft motors were no introduced until the '86 3.4L Mercurys. Prior to that, you had to buy an extension kit to get a 30" motor. OMC intro'd a 30" shaft the next year, in '87, and I think it was initially available only on the V8s, but I'm not sure.

As I think about it, I remember we notched the transom on a 25' Robalo CC that had twin 115's and put on a single 25" 235 EverJohn engine back in '84.
