    WTF do I have? Help me identify this motor

    Just bought a 92 Whaler Rage which usually comes with a 650 powerplant from a 92 WR3. I am an older Seadoo guy so I am no stranger to rotax engines...but I am in the dark with Yamaha. Stampings are 6m6 on the crankcase, 61x on the jugs. I can't identify the aftermarket head or find any info on the pipe. From what I can tell by the previous owner he was an airplane mechanic that new nothing of pwc...example..he put an electric car fuel pump inline because the built in ones weren't working....enough said. I'd like to figure out what I have, and make sure it's as reliable as possible with kids using it. I'd prefer to drop back to a single carb. Please help me with some info on what powerplant this is.

    Looks like a Yamaha 61X that has been converted to a twin 38 carb set up with a protec pipe on it.

    Yes Yamaha 61X, they are great motors, reliable and parts are plentiful and cheap. That pipe and dual carb setup are not stock though
