how to flush a mercury outboard motor

This video is for all outboard that have a top connection. you don't have to flush it like this every time, but every now and then would be good for the motor to completely remove all the salt out of your outboard motor. p.s this day I was suppose to go out on the boat but overslept smh. #tracker #basstracker #outboards #boat #clean #fishing

Couldn’t get my Mercury to pee after bringing it out of winter storage. Watched this video, flushed it through the top hole (without running it), and now she pees like a racehorse. Great video!

[@petemoore8923]

I bought a quick disconnect hose setup. You don’t have to spin the whole hose when you connect up top.

[@robertsalter2486]

Great. Fast and Easy.😊

[@AxelCadenasJr.]

When you say "the motor being hot" am I still good to flush the engine that way after a 45 min ride home? Would the motor still be hot at that point or is that just recommended for using right after u shot off the motor?😊

[@RobertDobosz-qk1zs]

I have water exiting inside the engine cover through a port on the starboard side is that suppose to happen.

[@joshiguchi4442]

So, is it required to do both flushing (top port and ear muffs)? Do they flush different parts of the engine? Thnx!

[@APiIeOfPoo]

Thanks bro my XL wasn't peeing after this winter. After flushing it this way its back normal flow.

[@robrandolph9463]

have u changed thee impeller. ??

[@camryntucker4282]

What is the hole underneath where you hooked the water hose?

[@bobellis1994]

I have no Tell Tail on muffs any suggestions

[@ron9748]

Love your videos. I'm picking up a classic in 2 weeks, can't wait! Saw your 2nd gas tank in another video. Where'd you get it and what brand is it?

[@Carlosboatingadventures20007]

Thank you!! Did you get your new boat!? And I got it at academy. I do not remember the brand name.

[@ron9748]

I did! I love it. Haven't fished fresh water in decades. Literally. Had it on the Colorado a few times where I plan to concentrate on Flatheads. Have a 12 gal Moeller gas tank on order. Wanna do a bigger cranking battery and add another trolling motor battery. Would love to do a bunch more stuff (and I will) gotta wait for my budget to match my needs (wife claims they're wants) :)

[@theowenssailingdiary5239]

Some models require the engine to be running for the top hole method. Mine does. Read the manual.

[@frankkyne6711]

That’s what my Manual says also and that’s what I do

[@lukefh3093]

Same here

[@Therapy-n-Session]

Have you heard about the recall on the seats?? I had to return my boat back to BassPro because the seats are on recall.

[@Carlosboatingadventures20007]

I have not. I need to check that out and give them a call. I wonder what part there replacing on the seats. But thank you for letting me know 💯

[@TheBaker999]

Thanks saved me from having to take motor in

[@Carlosboatingadventures20007]

No problem, thanks for watching!

[@Legnerps]

All mercs? My 2023 25 hp ?

[@jennymallin9404]

Did you have the engine on when you did the top flush

[@Carlosboatingadventures20007]

No have the engine off when you do it.

[@ruddugger]

The mercury owners manual says to turn the motor on when u connect the hose to the top outlet

[@tone-np2mf]

i have a 2021 Boston whaler 60 hp and i have been told by many boat mechanics not to start the engine when you do a top flush because i will burn my engine out.. but my Mercury owners manual says turn the motor on when you connect the hose to the top outlet so just to make sure i called mercury and talk to the warranty department they ask for the model number and serial number for my engine and they told me this is a brand new engine and do what the owners manual says.. keep the engine running on a top flush especially that the engine is under warranty..now I'm thinking maybe the older models mercury engine you can't run the engine on a top flush because you might burn something out..just to make sure i would call the mercury 1800 number and give them your model # and any other numbers they might ask for just to be sure because you don't want to burn your engine out..

[@ryant651]

@@Carlosboatingadventures20007 Yes, for a 2016 Mercury 115 EXLPT 4S service manual requires engine to be off as flushing from the top is a back flush. I suppose other merc engines top flush that requires engine to be running, feeds into the inlet of the water pump. If not, your water pump will be fighting water hose pressure.

[@Nardage]

Hey could I drop my boat in a fresh water lake to clean the motor out ?

[@Carlosboatingadventures20007]

Yes you can. If I go in fresh water I won’t flush the engine at all.

[@Therapy-n-Session]

Damn dog I have the same boat and I didn’t know about the top port 🤦🏾‍♂️🤦🏾‍♂️🤦🏾‍♂️

[@Carlosboatingadventures20007]

😂 really!? Not a lot of ppl flush it that way. But it’s good if you want to clear all the salt out the motor before storing it for winter or a long period of time.

[@Therapy-n-Session]

@@Carlosboatingadventures20007 so does the motor have to be warm to use this port

[@Carlosboatingadventures20007]

@@Therapy-n-Session yes that way the thermostat opens up and you can get a good flush threw the motor.

[@alekkoneil2144]

😊

[@jponyboyace]

Big part of the flush is do not start if you r doing a upper flush

[@andrewhardcastle7982]

Shit learnt that lesson the hard way 😡

[@lukehartle5600]

The manual says to start the engine in idle when using the top flush port and run for 3 to 5 minutes in order to open the thermostat

[@perfecthourglass]

Yeah the manual says nothing of muffs and just talks about that top port and says to run it which makes no sense because it's otherwise an output. What's with that?

[@perfecthourglass]

Do you know why the manual says to run it when you obviously shouldn't?

[@lukefh3093]

​​​​@@perfecthourglasswhy should you obviously not run it? The manual for my model (20HP 4 stroke EFI 2023) clearly states that when you use the flush port, to run the engine for 3 to 5 minutes in order to open up the thermostat so fresh water can get into the whole cooling circuit. It says do not run it above idle. I'm pretty sure you're not going to burn out your impeller as long as you don't rev the engine above idol while it's being flushed through the port hole that's specifically designed for flushing. The internet is a total clusterf*** of misinformation on this stuff, just follow the manual

[@johnhamilton4423]

Looks like you don’t run the motor…like the mercury marine video suggests

[@southernslipping4225]

Don’t see what flushing helps it flushes it self

[@JackSon-cs5vk]

can i start it with the hose screwed straight in?
