- How to winterize a boat. Step by step easy to follow instructions of how to prepare your boat for winter. I did this to my 4.3 mercruiser but, it is similar to the 5.0 and 5.7. Volvo and OMC can be done like this too. I have other videos of my 3.0.
Step 1, Add seafoam or stable to your fuel tank and run it for 5 to ten min.
Step 2, Can skip this step, pull carb cover off and spray fogging spray into the carb till it kills the motor to coat the cylinders with oil to prevent rust pitting. Better for long term storage.
Step 3, Unscrew all 5 block and manifold drain plugs to get water out of motor.
Step 4, Pour Marine/RV coolant directly into hose until it comes out of the top and lower end.
Step 5, You don't have to but, I repeat step 3 and then 4 again just to make sure the coolant made it to all parts of the motor.
Step 6, Drain lower end. Recommended to refill it.
All done.
Make sure to fill with the antifreeze. So many people just drain the block. There's pockets that won't just drain. Can crack. Fill it up, be safe.
Very helpful tip.
and yet the volvo penta manual states just to drain it... 🤔
Great boat winterization video! Thank you for using our STA-BIL 360 Marine and STA-BIL Fogging Oil!
YOU DID AN OUTSTANDING JOB!!! I'm a first time boater w/250 express cruiser. LOVE THIS VIDEO!!!! THANK YOU SOOO MUCH!!!
Now that is one engine with the best acess that i have ever seen!
thank you CHRIS JUST GOT TIRED OF PAYING FOR OVER PRICE WINTERIZING, GREAT INFO
The best video on this topic I have found. Thank You
That part about Engine i found this video and method the easiest ,was super helpful from all those youtube ive seen so far
Thanks 😊
I love the coffee cup! I have several of them myself!!
I bought mine in Houston TX at the space center. I love that cup
@@BigIslandMNMinnetonka I work at GSFC Wallops Flight Facility so I get them from the Exchange on base. The Space Center is awesome! Have you been to Huntsville? Also, I have a MerCruiser 350 MPI (fuel injected). What do you recommend for it? I figured that since it is not carbureted that I don't need to try fogging anything.
Great video. You saved me money doing it myself vs taking it to the marina!
Great video, going to try and winterize my Mercuiser 4.3 today based on your videos. Thanks for answering a lot of questions in the comments, I found that helpful also!!!
Hope it helped. Thank you for watching
I’m gonna be doing my Volvo 5.7 very soon and making a video. I was planning on using the Camco jug with the valve, but I can’t find the Volvo pump adapter anywhere. I like your method better. Good job!
Thanks for the video PEANUTBUTTER CUPS!! 2:33
Lol.
Thanks so much the videos you do! They are very helpful!
nice! ...and engine oil and filter change using manufacturer's oil specs....
Northwest life? Where are you from?
@@BigIslandMNMinnetonka originally Coos Bay, Oregon.
Do you leave the coolant in the block or drain it back out?
Great stuff Chris. I also watched another vid on getting the antifreeze into the block where they used sealing ear muffs and sucked the antifreeze directly (whilst running) from 3-gallon jugs after draining. They also did the fogging upon completion/while sucking in the last gallon of AF. They also said the fogging should run until you see blue smoke, then kill the engine. Thanks so much for the details of plug locations which is why I am here. BTW, you said in your vid 50 degrees, I know you meant to say -50 lol..
Yep. -50 burr
Chris, great video. I live in MN and have watched a lot of your videos which helped me buy my first boat this year. Now on to my first season of winterizing myself.
Question, I have a meec 4.3 (2004 mfg date) but I have 6 hoses instead of 4. Any idea if I should pour coolant down the same hose as you did in this video?
Also, I see you only poured coolant down one hose in this video, in others you have poured down the forward (bow end) two hoses. Any reason? Also, do you recommend changing oil/winterizing on a level surface vs an inncline driveway? I noticed you do this work on the street in most videos.
Thanks for the help!
when you drain or fill the outdrive it should be fully DOWN
Correct
Hey man, thanks for all the boat vids. They have been super helpful. I've got a 305 from 1990 and can only find the manifold and block drains. 4. It doesn't seem to have the one on the front starboard by the fuel/water separator. Do some motors not have that one?
I did everything just like you explained. I did not notice any pink coming out of impeller housing though...... Am I still safe? I mean I flushed that thing full pink, I just never saw any come out of the impeller
I'm sure it's fine.
i don't get antifreeze coming out of my manifold drain plug after i fill up the manifold hose. Any idea why? is it because of boat angle? Jay in Northern Alberta.
Poke somthing in the hole. Rust flakes can clog the hole. Every year one of mine clogs
I noticed what looked like a large crack in your engine support not good if wood under the engine starts to rot.
Its been like that long before I got it. My uncle owned it before me and my grandpa. It has been dry. I am have a guy at a boat shop fix it in spring. I was watching it to see if it would get stressed or worse with good use. It hasn't so, a fiber glass fix was recommended
@@BigIslandMNMinnetonka I commented on those cracks a few months ago in one of your other videos. I have the same boat, same cracks. Did they say what the repair is going to cost you?
shouldn't the outdrive be in full down position when filling with gear oil?
It is best
Hi Chris, general question here, does the marine antifreeze eat the plastic impeller?
I've never heard of it eating it.
Boy, they sure could've made it a bit easier...
So I have those two blue drain pipes on my 3.0 mercruiser. How do I add antifreeze to the exhaust manifold and block?
By undoing the coolant lines near the thermostat and filling those.
Hello Chris
I have heard some times those blue plugs snap off when trying to remove, which makes me nervous if it breaks.
Have you heard this before?
Thanks
Kevin
Yes it can happen. If the do break off they are easy to drill out since they are plastic.
Can you link the stuff used in the vid in the description?
Don't you want the outboard level when adding gear oil?
It is best. To prevent air bubbles
Hi Chris, I am planning to winterize my Volvo 4.3 this weekend and watching this video helps very much so. I do have a question, do you leave the antifreeze in there or drain it all out? Also, will I need to fill the tank with as with the stabilizer or just enough in there? This is my first time doing this so I am very unsure.
You can do either. Leave antifreeze in or drain it. Some say leaving it in prevents rust. Unsure if that is true. I prefer to drain it. You don't need to fill the gas tank. Put the amount of seafoam or stable in the jug says that you need. Some say fill the tank to prevent condensation. I think you get condensation anyways. So, in my opinion it doesn't matter. Less old gas to burn in the spring the less you have in the tank.
Video was 👍 thanks, you use -75 antifreeze for Minnesota, i live in Florida, and can i still use the boat with the new antifreeze in? Im planning of using my boat till the end of October Mid November. 🙏🏽
You can use the boat with the pink anti freeze. It should not be bad for the environment. -75 antifreeze might be a little over kill for you down there.
@@BigIslandMNMinnetonka I hail from central MN. Nothing is overkill here. I know you know what I'm talking about there
@@dereks4497 I agree. What town in Minnesota? I'm SW suburbs
@@BigIslandMNMinnetonka . Hey Christ PLEASE ADVISE....My engine is a 1993 Mercruiser 5.0/LX , I only found one plug and I believe is from the block so I drained it, I unhook all the hoses since I couldn't find any other plugs. If I pour antifreeze same way you did troutout that hose, will the antifreeze get to the block? Just want to be safe. I'm in Mryland not s cold as Minnesota...it gets barely to 10.
Thank u
@@edil.lopezm9443 it should reach block. Keep pouring it in untill it's pure pink coming out
How often should you change the trim revisor fluid?
Maybe every few years. Some people never do
anybody got thirsty after watching this video?>
I poured 3 gallons of antifreeze, half thru the Block side hose and half thru the manifold hose that connects to the intake of water. Problem, antifreeze did not flow out through water intake slots. ...did I do something wrong? In your video, the pink Antifreeze poured out of these water intake slots.
When you pour into the big hose. Plug the part it hooks up to with a rag. Then pour into there. Maybe the plugs are clogged
Great video! This question might have been asked prior but do you drain all the antifreeze out of the system or do you let it sit in the block? Also, when pouring antifreeze into the smaller pipe that goes to the lower unit, do you have to do it when the engine is hot?
No the engine doesn't have to be hot and yes it goes to the lower end and yes you can leave the coolant in the motor. It doesn't matter either way.
The two hoses go to the manifolds
@@BigIslandMNMinnetonka I've heard most shops recommend draining it after. I suppose it doesn't matter either way. Thanks for this video.
The coolant adds corrosion protection for the water jackets, provide some rust protection .... Only reason to leave in . Many argue to drain is best, air won't freeze? Mine gets filled -100 blue!
Do you warm the engine to open thermostat and then drain and then add antifreeze?
YES...10 minute warm up should do it
Hi do u know why all the antifreeze i put in goes down the lower end ?
It should. Pour some in a different hose. You must be putting it in the hose that is suppose to bring the water from the lower end to the motor.
We put it in all three hoses though
What about the pump for the live well? Does it retain water?
I don't have one. If I did. I'd pull hose off pump and let it drain
Hello I leave in apple valley mn. Where you buy -75 antifreeze
Menards eden prairie is where I get my -75 degree antifrerze
@@BigIslandMNMinnetonka thank u Chris i have my boat winterize today with _50 hopefully work thank u
Just bought Prestone -100 RV Antifreeze from Walmart, Eagan
@@bziton thanks bziton next time. For sure
Is it necessary to warm up the engine before adding the antifreeze flush. With the thermostat closed will u still get antifreeze everywhere in manifolds and block with engine cold.?
You Don't need to warm it up if you direct inject the antifreeze. If you do it with a bucket you need to warm it up.
X
Chris Boats how do you direct inject.
How do you DIRECT INJECT the antifreeze?
Pour into hoses
Would it be better to run the engine while sucking in the coolant? Or is simply adding it through the thermostat hoses enough? By not running it would any passages be left free of coolant?
I prefer adding through the tubs. Both ways work. If you run the motor make sure ut gets hot enough that the thermostat opens otherwise coolant won't get in everywhere.
Easier to hook up atifreeze to muffs and just run it through the engine until its pink coming out.
I have the jug to do it that way. I'm scared the thermostat won't open and it won't go into the block all the way. Also, some people can't start their boat / won't start. This works in that situation
The way you are wasting coolant here makes me think this is pretty cheap coolant. I thought there is specific coolant to be used for the motors to avoid freezing over?
4 per gallon. It is RV/Marine coolant.
@@BigIslandMNMinnetonka I thought the stuff for portable water was a no no?
I went to buy stuff at Walmart over the weekend and said it was not suited for engines
@@PMPerformance I've been using it for years. Never a problem. Maybe put it in and then drain the block if you are worried.
Guy is kind of messy
Lol
This method doesn't address the water pump impeller and associated passageways that will have freshwater in them. The last step should be running the motor and draw some coolant through the water intake to dilute any lingering raw water.
This will also add coolant to a power steering cooler if equipped.
my thoughts exactly i always heard you have to run the boat on muffs to get the thermostat open then switch to antifreeze through the muffs to suck it through the impeller untill it runs pink out the exhaust i see a lot of guys missing this step
