Inboard boat Winterization - Ski Nautique winterization

[@tomhurstdrums]

Thanks so much! This video is a huge help for my novice self. 😅 (Just bought my 89’ Nautique last March/got in about 12 trips this summer.) Wanted to make sure I properly winterized the boat for this winter here in Nashville. So appreciate your detailed and informative video. Gorgeous boat as well. 😊👍

I have an 89 ski Nautique that I’ve owned for 23 years and have winterized it myself the entire time. A few things I would add… You should all the time but, definitely use 90 rec fuel on your last tank and add stabilizer so when you’re running it for the last time, the stabilized fuel is completely through the carburetor. I unhook the lake water intake hose from the grate on the bottom of the hull and use a large Rubbermaid container that I bungee cord to the swim platform. I run a length of garden hose to the container at the back of the boat and add 3 gallons of RV antifreeze and just let it circulate through the engine until it gets to temp, then fog till it dies. While you have the engine warm, it is a good time to change the oil since it Hass to run through the small diameter hose and out the drain hole. After that, I remove the battery to keep it on a tender and remove the impeller from the raw water pump, so it can relax over winter and/or replace it for the next season.

No need to accessorize your bucket. Just warm up the engine, pull the hose that pulls the water from the lake, the one that runs to the raw water filter, and put that hose in the bucket full of antifreeze while the engine is running until you see it coming out. That will also fill your raw water filter, so no need to manually fill it. A lot of this is preference, and even more is location, but I’m in the Charlotte area, and hardly anyone fogs their engine these days in this area. I have a ‘98 I bought new, and it still runs like a top with over 2500 hours. All the best…

Hi Brett, Not putting my Starcraft away yet till winter this year. They opened up Coho fishing on Lake Washington for the first time in years. The Coho run is super good this year and is open till November 30th.

Nice work! If you add a Flush Pro Kit to the system, it will be just about as easy to run your procedure! I do the same thing for my 92 Sport Nautique and my 2002 Malibu Sportster

I'll check it out. Thanks

some insist that after this, you drain it out of the drain plugs...which makes no sense. why use antifreeze, if you are just going to drain it out?

[@ffhd1clt]

This is so you don’t have to keep removing the drain plugs. In fact, that’s why I started doing it this way, because those plugs start going into the block a little deeper each time you remove them and replace them. I don’t do the antifreeze exactly this way either. I just warm the engine, then pull the hose that pulls the water through the hull from the lake. I put that hose into a bucket full of antifreeze until I see the antifreeze coming out the exhaust. This is much easier, and there’s no need to add the threaded piece to the bucket or fill the raw water filter because this way it will fill itself.

[@kevinlang4134]

When you say it’s running with the water hose on, is that hose hooked up to the boat somehow? Or are you having the boat running without water hooked up at all and just relying on the antifreeze to push through?

[@bucksgarage1]

It is running off a water hose. I show how it's hooked up 35 seconds into the video

[@jeffgilliam9627]

Do you need to drain the water out of the plugs in the manifold first? Or does it not matter since we're running the water out of it?

[@bucksgarage1]

Nope. You are flushing the complete system with the rv antifreeze

[@craigmerrill2156]

Anything on the trans to worry about?

[@bucksgarage1]

Not that I know of.
