    De-Winterizing

    Hey guys,
    I winterized my 2 93 SL750's and I just wanted to know if there is a right way to de-winterize them. I am going to put the tripple fuel pump on these and change all the fuel lines. Any additional help on doing these 2 tasks would be greatly appreciated.

    Thanks in advance
    Rob

    Have you looked at the Service manual?

    Read the sections on regular and periodic maintenance, and the winterizing section. That is a good start.

    There are fuel lines inside the tank that also need changing. Be sure not to lose the metal restrictor located inside the return fuel line. Transfer it into the new return fuel line, and clamp it in place. And make sure you connect the fuel pump output to the carb inlet nipple, not the outlet nipple.

    Don't forget about changing the oil lines and oil filter, and bleeding the air out of the oil lines. Pre-mix the first tank of fuel to ensure engine oiling while the last of the air bubbles work their way out.

    Inspect everything, just to be sure. Nuts, bolts, hull cracks, electrical connections.

    Lube everything that moves, with the appropriate lubricants

    What he said. ^^^^^^

    Also when doing the fuel hoses, do 1 at a time as to not confuse them. Also install new fuel filters if so equipped.

    Inspect/clean the fuel selector valve.

    Remove the autocock if your skis still have them installed. (looks like a small fuel pump)

    Check out the triple outlet fuel pump instructions to familiarize yourself with the install before you do it. (It's in the tech section under Fuji fuel)

    As far as de-winterizing,make sure the battery is fully charged,sometimes after sitting all winter it could go bad,make sure it cranks/starts good on the trailer in the water before launching.

    It will smoke for a while till it burns off the fogging oil.If the fuel tank was not filled in the fall,fill the tank with fresh gas.

    A common mistake with new PWC owners is using batteries that are old and internally weakened.

    If there is any question about the quality or health of the battery, replace it.

    Best battery type for PWC is the factory sealed AGM type, such as the Deka ETX16LM, to the Odyssey PC625.

    Sealed AGM batteries will not leak acid, even upside down, are very robust, provide strong starting power, and have very slow self-discharge. An AGM battery can sit for months and still have plenty of starting power.

    Not only must the battery provide over 10.5 volts while cranking the engine, the battery must provide enough reserve capacity to repeatedly re-start the engine. On the water, you want to be sure the battery has the strength to get the engine started, every time.

    Being stranded on the water is not a good thing.
