The Sunk Ski Procedure: What to Do When Your PWC Goes Under
It happens to the best of us. You’re out for the first ride of the season, the weather is perfect, and suddenly, you misjudge a wave or a turn, and the ski flips.
Recently, we had a customer experience exactly this on their maiden voyage of the summer. They accidentally flipped their Sea-Doo GTI and struggled to get it upright in the chop. By the time they got it flipped back over, the hull had taken on a massive amount of saltwater.
Fortunately, they did the smartest thing possible: they got it towed to the ramp and brought it straight to our shop immediately. We dropped everything and got straight to work.

If this happens to you, your machine is on a ticking clock. Here is the Odyssea Sunk Ski Procedure and why treating it like an emergency is the only way to save your engine.
The "Golden Hour" of Saltwater Damage
Here is the hard truth: If your ski sinks in saltwater, you have minutes to an hour to act, not days. Saltwater is highly conductive and incredibly corrosive. If it sits inside your engine compartment, it will immediately begin eating away at your electrical connectors, sensors, and the ECU. If water got inside the engine block through the air intake, the internal steel components will begin to flash-rust almost instantly.
If you sink a ski on a Saturday and wait until Monday to call a mechanic, the "Saltwater Tax" will be absolutely brutal. Heavy corrosion will have already set in, turning a manageable rescue job into a complete engine and wiring harness replacement.
The Sunk Ski Procedure (Step-by-Step)
If your machine goes under, follow these steps immediately:
1. DO NOT Try to Start It
If your ski was upside down, there is a high probability that water entered the engine through the air intake. If you hit the start button and the cylinders are full of water, the engine will "hydrolock." Water does not compress. Trying to turn over a hydrolocked engine will bend your connecting rods and destroy the motor instantly.
2. Get It Out of the Water ASAP
Secure a tow and get the machine back to the boat ramp. Pull the drain plugs immediately as you pull it up the ramp to let the bulk of the heavy saltwater drain out of the hull.
3. The Freshwater Flush
Once the ski is on the trailer, you need to attack the saltwater with fresh water. If the engine compartment was swamped, hose down the entire inside of the hull, the outside of the engine block, and the wiring harnesses with fresh water to dilute and wash away the salt. If you have a shop vac, vacuum out the standing water in the bilge.
4. The Chemical Shield (CRC 6-56)
This is the most critical step. Once the heavy water is out, you need to displace the remaining moisture. Grab a can of CRC 6-56 (or a similar high-quality marine water-displacement lubricant) and spray everything. Soak the engine block, the electrical connectors, the ignition coils, and the wiring. This creates a chemical barrier that forces the saltwater off the metal and stops the corrosion process in its tracks.
5. Get It to the Shop IMMEDIATELY
Even if you get the exterior of the engine dry and coated in CRC, you still need a professional to extract the water from inside the engine. At the shop, we will pull the spark plugs, pump the water out of the cylinders, empty the airbox and intake manifold, preserve the inside of the motor, and perform a series of rapid oil flushes to get the milky, water-contaminated oil out of the crankcase before the bearings are destroyed.
Part 2: The Reality of the "Saltwater Tax"
On that Sea-Doo GTI we showed in the first video, we followed the exact procedure above. We got the water out, pumped the cylinders, and completely preserved the engine block. But when we went to start it? Zero power.
We diagnosed the ski live on our Shop Cam, and the results are a brutal example of why saltwater is so destructive:
The Diagnosis:
Heavily Corroded ECU: The saltwater penetrated the main computer connections, causing the metal pins to literally break off inside the unit.
Destroyed Wiring Harness: The saltwater wicked its way through the main harness, rotting the connectors from the inside out.
Because saltwater is highly conductive, it destroys electronics in record time. Even though we saved the expensive engine block, the customer still had to replace the ECU and the main wiring harness. It's a tough lesson, but it proves exactly why every second counts when your ski takes on water.
