    97 SLTX 1050 having issues.

    I took the purple monster out today for the first time in a long time, everything was going fine. I eased it up to top speed (about 53) and cruised around the lake for a little while... then I was doing donuts and it started to bog down.. it seemed to not want to really get up and go out of the hole. I tried to get back up to top speed but it wouldn't go any faster than 40 mph @ 5400 rpm. It actually sounded like it was running fine, the only recent work done on it was a CDI and stator install. Anyone have any ideas? Bad/water in the gas? carbs need to be cleaned? I really need to have it running well by Sunday. Thanks

    What is the maintenance history on this machine?

    Was there water in the hull?

    What diagnostics have you done so far?

    Other than shout profanities at the ski, nothing yet. Advice on route I should go? There was a little water at the bottom of the hull but not much.
    Every year it has been taken to a dealer to be serviced. I can't verify 100% but it was a buddy's ski and he usually takes good care of all his toys so I don't have any reason to doubt him.

    Ok checked compression, good in all 3 cylinders. But I did notice the ski has the tempo fuel lines. I'm going to replace them today if I can get ahold of some new ones. Spark is good too, they are new plugs and the carbs were cleaned when I had the stator and cdi put in.

    When my 1050 was running on only 2 cylinders-the rpm's were 5400.
    How do the plugs look? Plug wires trimmed ?
    You could pull the plug wires off one at a time-verify all cylinders are contibuting.

    Well, that says to me that you can not assume it was properly maintained. Service shops that are familiar with these older watercraft prefer to replace old fuel hoses, even if they are not the gray Tempo stuff.

    Tempo fuel hose troubles are widely known but some regions seemed to have less problems than others, possibly due to the local fuel quality. Ethanol is one factor known to degrade fuel hoses.

    Carburetors were 'cleaned'? Either they were taken apart and properly rebuilt, or not.

    You have to remember we are talking about boat shops in Montana.. They aren't exactly top notch. I bought some new fuel lines and will install them tonight. K447 you think its the carbs?

    If you don't know what was actually serviced and maintained, you have to assume it was not.

    That means you get to work through the diagnostics until the problem reveals itself.
