All white with a orange stripe and lettering. Might have been the commercial motors. They were the bigger c.i. head.
The newer thru hub models were detuned because of emissions. They are pitiful for a 25.
I think I know the ones you mean. They had the old style lower unit. The props were exactly the same...looking. The new, bigger power-head was used in 1977 with the old 'pin-drive' propshaft, only one year. Starting in 1978 they used a splined propshaft. The old style props were used but they had a splined hub pressed into them.
There is nothing pitiful about these engines...if they're in good shape. You may have experienced a 'well worn' old thing with a million hours on it. Maybe you had one once and couldn't get it going, I don't know. In any case, you have been deprived of the pleasure of running a healthy OMC 25hp outboard. Your opinion would be different.
They were eliminated from production probably for emission related reasons in 2005. They were certainly never de-tuned.
Maybe I can't put you in the driver's seat, but, here's a couple of videos: (If prompted, use guest password: twist'er)
