There were several of those versions of Stingers around here but???
Just like that OMC GP 4 cylinder engine that remains a mystery west of here, several Stinger engines were around here too with those racing gearcases but the only thing I found were some blown up ones, mostly scavenged for their remains and gearcases long gone. A fellow in these parts built a Popular Mechanics tunnel for that version of Stinger but ended up killing himself when they finally put a Merc V-6 and racing tower on it. The boat itself was on a trailer put up for sale years ago with the OMC tower and clamps on the transom but nothing else. By the time I got there that was all that was left was the crashed boat and that tower and clamps. Some of that stuff still must be around here somewhere.
