Your picture looks more like a cross-flow cowling to me. The loopers beveled off at the top, and the cross flows were flat and boxy. If it is a cross-flow200, then it is an 85 or older. In 86 the 200 cross-flow became 150 or 175 depending upon wether it was a feeshin motor or a pro motor. The 235(AKA 2 thirsty 5) became the 175, or an XP or GT pro style engine. It doesn't appear to be a looper cowling to me, but I could be wrong(been wrong many times before). It also appears to be a 20 leg on it which will allow more engine choices. Remember that you can run a 25" shaft opn a 20" transom with a jack plate, but you can't run a 20" shaft on a 25" transom without cutting it down to a 20" or going with a setback bracket.
