    ultra 130di question

    What would cause an ultra 130di while on the trailer running on a hose rev up and down without touching the throttle? It's hard to start and you have to work the throttle to keep it running till it gets warm then it reves by it's self up and down from around 2000 rpm to around 70000rpm. Compression is good and computer has been checked and shows to be good. Any help would be appreciated. Thanks!!!!

    Those skis have ALL kinds of electrical gremlins. We had one. Ours never broke but it did have a bunch of odd electrical quirks that NO one was ever able to figure out. It would shut off at random but then start right back up. The battery continually died. We had sporadic idle issues now and then and we had a brief issue with the engine rpms racing while at idle.

    From what I understand, these type of electrical issues are common to the 130 but the main issue and biggest concern is that eventually the ecu will blow out and cost $$$$ for you to fix. Apparently it happens to all of them and its only a matter of time. You should read up on it thats why they werent popular and only around for a little while.
