  • Ultra 130 won't get past 4mph!!!

    I rebuilt my Ultra 130 di engine (new crankshaft, pistons, gaskets) and put it in the water yesterday. The ski started up great and sounded like it was running fine in the water. However the RPMs stayed at around 1200 and the ski wouldn't go any faster than 4mph. I put the throttle wide open and it still stayed the same. Any thoughts? I didn't make any adjustments to anything when I put everything back together (SBT instructions didn't mention anything about doing anything like that). What do I need to do? Would it have anything to do with the cables going to the throttle/intake assemblies?

    Wow, almost a month without a single reply...pretty sad for a forum. I figured after spending over $1200 on stuff from SBT they could at least provide some feedback to a problem.
