Getting a Water Flooded 2 Stroke Running
After being around Sea Doo PWCs and rental businesses for years, I've seen many flooded 2 strokes!
Obviously, the water has to be expelled and the ski rode promptly after you get it running again. Here’s how I do it...
- First, hook up a 12v cordless booster to the battery. If you don’t have one, a battery charger will do. If you don’t have a charger, connecting the battery to a car with jumper cables will also do, but don’t start the car
NEVER JUMP A SEA DOO WITH A RUNNING AUTO OR YOU’LL FRY THE IGNITION MODULE QUICK!
- Next, remove the plugs and spray them with starting fluid or carb cleaner to expel the water off the plugs.
- Once the wires are on the grounding posts, put a rag over the head so when water is expelled from the cylinders, it doesn't spray all over you and the surrounding area.
- Next, crank it over until a majority of the water is out before then placing your thumb over each plug hole to draw more water out. After that, squirt some premix gas into each cylinder (I use a contact solution bottle to hold it and make it easy to squirt).
- Reinstall the plugs and wires then hold wide open while choking and cranking. It should "kick" but may not fire the first time. I usually have to repeat the whole procedure above a couple times but then it will fire and most times will run fine.
- Once running, you really need to take it out and ride while doing spins/sharp turns to try and get all the water out of the crankcase.
- Finally, once back at the dock and on the trailer, wash the engine compartment down thoroughly, let it dry, then spray it down with lube.
I've never had further problems when I follow those procedures.
One further note though... if you notice the injection oil looking milky from water in the tank, you also need to drain and clean it out as well.
