I just bought a 1992 Dynasty Elanti 191 with a Yamaha L4 3.0 sterndrive. When I bought it the engine cranked effortlessly however she was not in the water so I did not see her when she accelerated. I took her out today and everything went well until we accelerated up to 2000 rpm at which point she stalled out. She kept doing this over and over until we just limped back to the ramp and gave up for the day. I do not have a repair manual at this time (it will be here Tuesday). In searching the forum I see this issue happens with the shifting cables. Some have suggested it could be a fuel or carburetor issue (the boat will now turn over but not start). I'm at a loss. Any help or guidance would be appreciated. Mechanically I'm pretty good with engines if it is nothing major. This is my first boat I am just learning everything.
