I'd say that engine is worth at least $2500, or even more--of course, to the right buyer. As soon as my response pops up, surely someone will respond with a "I can buy 140s all day for $500".
It's cylinder displacement is 99.6ci.
The 140 Sport was nothing more than a color scheme by 1981. It is a 140, no more and no less. It's predecessors were the original 135 Silver Starflite (1974-75) and then the 135-S (1976) and 140-S (1977). These were sold with standard power trim and SST propeller, where the "regular" 135 (and 1977 140) had no trim and an aluminum propeller. From 1978-up, "both" 140s (the standard and the "S") came with trim. By 1981 there was no "standard" 140, the one in your photo was the only one available.
It is one of OMC's best engines ever, and will give your inline a run for it's money. Boat to boat, setup to setup the inline is likely faster by a mile on top, maybe a few even...but from a dead stop, the 140 will out accelerate it to the first turn easily.
