    Name that part (please)

    Okay, gurus, I need some help sorting out what I have here. I picked up a 94 SLT. Half of the motor was in it, and there was another motor and misc parts in a couple of boxes.

    First up, we have a pump assembly. Since I have 5 SL/SLT's I know this isn't from one of them.

    I'm guessing that pic #2 goes with this?

    Next up...

    What is this manifold off of? I know that the SL's differ from the SLT's because of the oil injection lines, but this is different than any of the ones in my pile. This one feeds to the carbs, but the nipples are stacked instead of side-by side.

    Also, I've not seen the spacer plate either on any of the ones I have.

    I am thinking it isn't a Polaris jet pump (not the148mm modular type, for sure).

    Yamaha perhaps?

    Finally...this is a pic looking down on the MAG cylinder. The rod shelled its nuts. I have a couple of questions on this one.

    1) Is the block ruined because of the crack/chip, or can SBT fix this?
    2) WTF is that screw in there for?

    Some early Fuji engines had a small zinc sacrificial anode tucked inside the engine water jacket. It was there to prevent corrosion inside the cooling jacket. Later model years didn't have it.

    According to the online parts diagrams, it was used in the 1993 Fuji engines (650, 750).
    3240131 PLATE,ZINC

    Looks like this engine has the screw, but not the anode.

    Sure looks like a 146mm jet pump to me.... 92 and 93 SL model years

    The pump shoe goes with it. (water inlet for pump)

    The intake manifold looks like a 92 or 93 intake. They used to have fittings for carb sync as well as the oil injector fitting.

    Can SBT fix the case??????

    Oh Boy........ (shakes his head)

    lol...It's okay; I have plenty of extra parts. What's funny, though, is that the rod is fine, so I can't figure out why the case is effed up. Even that jug and piston.

    Update: I just finished pulling off the intake..."intakes." All three of them are separate. I'll look a little closer at the motor. Maybe it was from a '93.

    Chances are someone reused the engine case and installed another crank and cyl. That damage doesn't happen without a bearing failure.


    Seperate intakes? I know the 92 650 had them, not sure if the 93 did.....

    What's the serial number stamped onto the case?

    Motor says 95-xxxxx

    Still stumped on the jet pump; All of my other boats have the long bolts, that's what threw me. So the earlier ones didn't?

    Correction: 93-02093 (amazing what you see when you remove the grease).

    Then this means they must've changed the flywheel and stator as well, right?
