It’s autumn, and time to take up the boat! We’re here with an Enduro 705 with a 250 E-Tec. We will look at how we winterize the
boat and engine. Preparations for winterization
starts before taking up the boat. Gasoline may actually perish over the winter. BRP, provider of Evinrude, recommend that you add this 2 + 4 Fuel Conditioner – – or equivalent products in the gasoline. This maintains the gasoline’s
qualities through a long winter. You add the amount specified on the label. Then you go for a tour. For the engine to be thorougly hot, you should
run it at least 10 minutes at 3000 rpm. That will open the thermostats and blow-off valve, and all cooling water is circulated. That leaves you with this mixture in the engine as well, so it’s not stored with bad gasoline throughout the season. Now the boat is on land, and we’re ready
to run the motor on fresh water We have two options. You can use the clocks, or
so-called “Mickey Mouse” ears. Double check your gearbox if you’re using these. If you have water intakes in front of the gear housing,
these should be taped again. Most engines today also have the opportunity to use
this 3/4 threaded coupling. We use this. The part where the cooling water
comes out, is threaded. Find the threads properly. Then we can connect the water and start the engine. If you choose to use bells, first unscrew the water intake. Then attach the bells. If you have water intakes in the front, they must be taped. Very easy with a wide tape. Squeeze it firmly. This allows you to maintain good water pressure
within the engine whilst running it in fresh water. Now we can connect on the water. Before you start the engine, you must wait until you see the flow of water out of the cooling water intake. Now we are confident that the impeller
will not run dry when we start up. When the engine has been running on freshwater for about 10 minutes, it’s time to winterize it. Here we have a G2. Press this hand icon. We get a screen with several choices,
including “Winterization”. When we activate this, the motor will increase the rpm. It will run on this speed for 1-2 minutes
until it stops by itself. Here we have a G1. The engine has been running for 10 minutes, and we press MODE. We choose “Edit Menu” and hold MODE. We scroll us to “System” and hold MODE. We go to “Winterization”. Here we hold MODE. We highlight “Yes” on “Perform Winterize”
and hold MODE again. “Advance throttle to 50%”. Then it will run at this speed for 1-2 minutes until it stops by itself. Now the engine is winterized. We connect the water
and allow the engine to drain. Remove the battery and top charge it. Store it in a cool place during the winter. It’s a good idea to do a maintenance
charge halfway through the season. It should fully recharged again before you place it back into the boat in the spring. Removing scales and fouling of the,
we use hydrochloric acid. This is strong stuff, take precautions. Use
gloves and goggles, and stand in a well-ventilated place. The acid is easy to use. Brush on, and rinse thoroughly with water afterwards. Think about where you do this. If you have paving stones or asphalt, it may get discolored. Check this first! Trailers that are galvanized will also react to the hydrochloric acid. I use a radiator brush to get
some distance to the acid. Use generous amounts. If the desired result isnt achieved immediately, you can do it in several stages. Let it react before rinsing off. It is also very effective against the yellow stripes at the waterline. Same procedure. You brush on, and immediately see the stains go away. Many try to polish and apply different products,
but hydrochloric acid is very effective. The acid also very effective if you have stainless steel details with a hint of rust. It is important that it is stainless steel. Aluminum will react with the acid. These boats have only stainless steel details. Brush on and let it react a little. Now, the acid have had time to react,
and we rinse it off with plenty of water.
