Preparing the inboard engine for winter? Flush Kit & Accessories

First, make sure the engine is ready to start. Then unscrew the cap from the jerry can and fill it with the recommended coolant. We recommend using approximately 10 liters of coolant for 4 and 6-cylinder engines and approximately 15 liters of coolant for 8-cylinder engines. This way you can be sure that the engine and manifolds are well soaked. If you have purchased the flush kit in combination with the fogging oil, you must first remove the air filter above the air inlet.

Did you order the complete kit including the fuel stabilizer? Then first add fuel stabilizer to the fuel (about 50 ml to 100 liters of fuel) and let it mix well while warming up, so that your fuel system is also well soaked. This way it remains optimally clean and fresh.

We have drawn up a nine-step plan to prepare the inboard motor for winter: 
STEP 1:
Fill your jerry can with 10 to 15 liters of coolant and make sure the tap of the jerry can is closed. Connect the garden hose to the coupling and turn on the tap of the garden hose.

STEP 2:
Place the jerry can on top of the back of the boat and connect the garden hose to the coupler.

STEP 3:
Push the flusher on the bottom of the lower unit, from front to back, over the cooling water inlet. Then check whether they are correctly positioned over the cooling water inlet.

STEP 4:
Turn on the garden hose tap.

STEP 5:
Start the engine and let it warm up for a while until the temperature of the cooling water in the engine is about 80 degrees, so that the engine's thermostat is open.

STEP 6:
Then open the tap of the jerry can so that the blue coolant flows out of the jerry can. Immediately close the tap of the garden hose.

STEP 7:
You can see the blue coolant flowing through the hose into the engine.

STEP 8:
Then look at the outlet where the cooling water flows out and wait until you see the blue coolant flowing out. As soon as you see the blue coolant, let it run for 10 seconds, so that the coolant can properly integrate into the engine. Then immediately switch off the engine or continue with the fogging oil as described in the next step.

STEP 9:
If you have bought the kit in combination with fogging oil, let the engine suffocate by continuously spraying it into the air intake of the engine until it runs off. Make sure you keep spraying well. Otherwise you run the risk that the engine will not run off. If, in the worst case scenario, it does not run off, turn the engine off manually.

PLEASE NOTE: Do not continue to run the engine when the coolant in the jerry can is empty. Otherwise, the engine temperature will rise and it will pump the coolant out of the engine again.

PLEASE NOTE: The engine must first be up to temperature (around 80 degrees). If this does not happen, the coolant cannot penetrate properly into the engine and you run the risk that the engine is not properly soaked with coolant.

TIP: Try to have someone with you so that he can turn off the engine on command. If you are alone, you can possibly tie a piece of string to the dead man's cord and then let it hang overboard. When you see that the coolant is running out of the exhaust, you only have to pull the string so that the engine stops.
