    98 GTX Limited

    Hi All

    My GTX Ltd started, to lag when it's pulling away in the water, but once it reaches top-end it runs fine. But when you leave the throttle, and suddenly give throttle again it has no power to pull away. It's if the ski has no power at low-end but runs fine at top-end.

    I'm no seedoo mechanic but I have a friend who is good with this sort of thing. He has serviced the ski for me, replaced plugs and did some general checks. Could it be the HT leads?

    At some stage the rpm dropped to 4000rpm and then jumped to 5500rpm and then it's if it got a boost to 6000rpm and runs about 80km/H

    Also the maintenance indicator is flashing on the electronic panel, could that be limiting the power? Also how do I reset the maintenance setting, without taking it to a dealer or is a special key or something required? ( Found the answer to this question on forum )

    First thing that pops in my head when you are talking about power surges is the fuel system.

    Does it have the original gray fuel lines? If so you will want to look into replacing those with regular black fuel hose from an autoparts store and also cleaning/rebuilding your carbs.

    X2...and don't forget the fuel selector valve.
    Over analizing is common...simple answers are few.

    Your fuel selector may even have a small screw on it where you can pull the valve from the valve body to clean, unfortunately mine on a 99 gtx didn't, but definitely something to look for. All the above worked great.

    Check to make sure the accelerator pump is functioning correctly.

    Please forgive me if this is a dumb question. How do I check the accelerator pump? Would it be in the shop manual?

    The brass fuel accellerator fitting at the top of each carb, with the smaller grey hoses attached to them often get clogged up and need to be cleaned. So look down the bore of each carb as you work the accellerator pump lever, and see if both nozzels are squirting fuel.

    The surging problem sounds more like clogged filters in the carbs or a faulty water regulator valve on top of the muffler. Could possibly be from filthy sticking rave valve guiotines too. When was the last service done to clean the rave valves ?

    Thanks for the info Mr. Bill, actually we are planning to service the ski ourselves, hence the request for help. Money is a bit tight at the moment. I don't actuall remember when last this ski has been serviced since it was standing in storage for more than 2 years.
