    Bosch Replacement Throttle Body

    Does anyone know ... my 2012 GTS uses a Bosch throttle body. The Rotax part number is 420 892 590. The Bosch part number on the back is 892 590. Doing a little research Bosch sells what appears to be the same throttle body for cars. Even the error codes seem to match what it throws on the seadoo. The auto version part number has a "-" after it with the millimeter size. I've seen someone on ebay selling the Bosch part (New) at half of the Seadoo price claiming it is an exact fit. Anyone know the MM or the Bosch replacement? $800 is a bit steep.
    I did find a picture of a Rotax throttle body on the Dellorto web site, they say model ML 46MM for recreation vehicle but couldn't fine where to inquire except in Italy. Does 46MM sound right? Thank You

    I believe I tracked down the Bosch part number 0 280 750 505

    Of course, now I cant find anyone selling it.. the 505 is the mm.

    Anybody ever used / ordered one of these?

    Any differences besides the color and the lip at the male tip?

    Whats even funnier is i think thats the same throttle body as a 2.0 Audi Quattro which all fail. That Bosch OEM number is the same.

    The TB is 60mm right?

    Then the Bosch P/N should be 0 280 750 151

    I've bought one and used it... It worked like it should. No issues at all.

    here's another source. https://www.europaparts.com/throttle...6b133062m.html
