Hello jet boat world. I'm kind of a FNG to the boat world. Couple years ago I came across a good deal on this boat. It is a 1977 Ranger guess built by GM. It's a 18' with 460,over transom exhaust. I did a little work to it. Put plugs,wires,new points. It runs very good. My question is,did they manufacture many of these boats? Cause I've been online looking everywhere for a ranger jet boat. All's I see is Tahiti,Hawaiian,eliminator,hallet all the brand names. Any info on this boat would be greatly appreciated.
