    Scarab performance mods

    I didn't see a Scarab forum? Ive got a guy locally that picked up a 250hp 195 scarab and i'm interested to see what we can do to it. I haven't looked at it yet but its suppose to have a nice external innercooler. Did Rotax change the supercharger or would a drop in ET137 work? I'm assuming Vtech can tune it? Im looking for any ideas on getting more power out of it

    The problem with the electronics is that Sea-Doo BUDS will not work on these boats. You have to be a Evinrude dealer to access to the electronics...We as Sea-Doo dealers can not plug into them.....

    Maybe CanDoo will make something for them?

    Looks like the same ecu setup as the normal ibr skis, so same as 260 engine in Sea Doo.

    I have seen them at boat fairs but not got the chance to play with the ecu yet.

    If you can , take the maptuner, plug it in and do a request on the ecu.
    Then we get some info from it.
    But we would most likely need to have a ecu at one of our dealers for 24 hours to be able to tune it.

    Scarab turbo next?

    I'll try to hook up the map tuner this weekend. Anyone know where to look for the port connection? I don't think this guy is ready for a turbo but a bigger drop in wheel with a tune would be right up his alley!

    Is there an on-line parts site for the Scarab boats? I'd like to compare some of the parts and the plumbing with the Sea-Doo Speedster.
