@@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, 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!!!
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!
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..
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.
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
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 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.
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!
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?
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 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.
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
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
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 . 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
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.
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.
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.?
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?
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!
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?
@@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
