I'm looking at one with 2 motors .I assume to go to a single I would have to look for 30" motor.Is this correct?Thanks
My memory isn't perfect, but here's a scenario which I think explains what you've observed: I think all OB's were 20" in 73 when the first 23's came out, and the biggest motors available were the Merc I-6 150 and OMC V-4 135, so most early OB models would have been sold with twins, and the boats may have been set up for 20" twins with a straight cut. The more powerful V-6 motors came out in the late 70's. If the 25" option came out with the V-6, they may have raised the cutout to 25" for twins, but then I think you'd need a notch for a 25" single.

These boats are old enough that many may have had the transom redone by now. The 30" motor is a relatively recent development, so you'd have to measure to check what length motor the transom was set up for. A redone transom might be set up for either 25 or 30" motors depending on when it was done.
