How i Flush my Yamaha Outboard 4.2 Liter V6 Engine DIY

[@ronbennett8026]

I've spoken to many certified Yamaha mechanics who all said running the motor with a hose connected to the flush port will not damage the motor. I flush with the flush port for about five minutes with the motor running, then shut it off and let it flow with the motor off for another five. Motor has over 1000 hours and it's been bullet-proof since new.

[@OutOnTheReef]

@ronbennett8026 That is great to know, but I don't know why the manual the manufacturer says not to.They must know something we don't know but thanks for sharing. 1000hr is awesome 👌

Running the motor with the hose flush does not provide water to the impeller. It is backflushing the water intake, so running your motor will suck air on the inlet side and push the backwash water back into the motor, leading to impeller damage and engine overheating.

@ronbennett8026 great point Happy Ours

Hi Capt... good info as always!.... Running and flushing the engine with the barrel of water is a great way (the best way?!) I'm sure. I can't do that since our boat is kept on a lift.... I flush our 300 Yamaha with the flush-hose for 15-20 minutes, immediately after I get the boat back on the lift; I flush it every time I run the boat, but I have never run the engine while flushing. I usually get water from the 'tell-tale'/ 'pee-hole' and the only time it is a weak flow is when the shore-side water pressure is low. (Our water company has 'pressure issues' sometimes). I don't know if the flushing gets to the thermostats and/or water pump, but I can say that every time I change the thermostats, they look like new; NO salty build-up and no corrosion. It's hard to tell the old thermostats from the new ones. Plus, most of our boating is in brackish and only minor-level salt water... The Atlantic Ocean near us is around 31-33 ppt salt. The Pamlico Sound where we do a lot of out boating is a third of that; around 19-24 ppt. The Pungo River is around 6-9 ppt and Pungo Creek is usually around 5-7 ppt, so that is also a big factor as to why I get little salt/corrosion build up... I have a some friends who never flush their engines, and a lot of the local crabbers who go out every day in season, never flush their engines... I will still always flush ours....

@andrewfyakim525 Hello, Andrew and you're right. Your water is not as salty as the ones we have here. The Caribbean waters are very salty. It's a matter of fact when I come from the Bahamas, there's a huge built of salt on the boat and doing the right thing. Captain, that is just plenty of flushing for your type of boating. Thanks for. Watching captain and have an awesome night

Great video. That’s how I run the engine with my boat on the trailer. For normal after use flushing (my boat is kept in a wet slip in fresh river water) I use the hose connected to the top flushing hose on the engine. I start with a Salts Gone or Salt Away with engine down and OFF and flush till product is gone from the little canister. Then I continue flushing/rinsing with plain water while raising the engine after a couple of minutes it’s done. I put the engine down on the kick stand and leave it up out of the water.

[@OutOnTheReef]

@@UrjunkMygold That is a great. Idea, captain.Thank you for sharing that with me.I will take that in consideration for my future flushings

[@KirkAllmond]

My 250 says in the manual that you don't "need" to run your engine when you use that hose port to flush it. It doesn't say you cannot run your engine using that. I can 100% confirm, it does work if you're running the engine and using that as the water inlet.

[@OutOnTheReef]

for my understanding the port works great too but the thermostat doesn't open , i like to bring engine to temperature because it takes salt deposits much better cap.

[@robertmoody2221]

I prefer this method as well, Good job captain 👍

[@OutOnTheReef]

@@robertmoody2221 thanms cap i think is the best way too👍

[@glenstuart7823]

From personal use I can reccomend Costco brand deep cycle marine batteries, they are made by interstate but relabled. Very good reliability and cranking

[@OutOnTheReef]

@glenstuart7823 Captain, I had those batteries before and they're excellent.Just a little bit more price

[@jeffreypinder9398]

Great job, Cap! Taking care of your equipment pays off! It's 36 F here right now and we are looking forward to 2-4 inches of snow thru this evening in the Mid-Atlantic. This coming week we have an artic blast coming so it will drop into the single digits. Stay warm yourself, I hear northern FL has some abnormal temps coming.

[@OutOnTheReef]

@jeffreypinder9398 wow cap. Sorry to hear that and yes is getting cold cap.thanks for watching cap

[@terryeytcheson1455]

Hi captain, you spoke to soon on the no snow, hope your not affected. Looking foreword to you next trip. Nav safe

@@terryeytcheson1455 lol cap And yes, you're right.It's knowing in Florida that's scary now.I need to winterize my boat🤣

[@DeepBlueChannelCom]

saludos capitan si lees el libro de la Yamaha te dice que el Lower Water pickup lo tienes que tape o una cinta yo uso algunas veces la cinta azul que venden en Home Depot que es para los remates cuando vas a hacer un trabajo de pintura

[@OutOnTheReef]

@@DeepBlueChannelCom eso no lo sabia capitan , jajaja parece que no leei el manual🤣

[@DeepBlueChannelCom]

@ sí capitan en los suzuki es lo más incómodo del mundo porque las orejeras cuando tú las pones en la pata de los suzuki tienen una curva que no sella bien y se vota mucho el agua pero Yamaha es más recto y puedes poner las orejeras de todas maneras a mí no me gusta ponerla para arrancar el motor porque la bomba no recibe suficiente agua el mejor método es ponerlo dentro de un tanque

[@DeepBlueChannelCom]

Y trata de que el nivel del agua suba por arriba de lo que es la bomba el Impeler ese es el mejor método para limpiar floshar el motor

[@OutOnTheReef]

@@DeepBlueChannelCom buena idea capitan asy hay mas pression👍

[@daverussell9875]

Your lithium batteries will be happier sitting around 80% for up to three months or better. But I agree 100% with your wet Cell batteries. That’s what I do once a month top them all off.

[@OutOnTheReef]

@daverussell9875 thanks cap. We think alike 👍😉⚓️🛥

[@Whalermansteve84]

My Suzuki 25 was having the same issue where it won’t pump water for a few minutes on the muffs , but flows good when I use the flush port

[@OutOnTheReef]

wow is scarry wen water doesn't come out quick cap , i burn my impeller housing one day like that

[@foreverfixin]

Good video buddy I am putting a system in my boat where I can put the ear muffs on my lower unit and wash out my engine using the water tank on board the boat good news captain my brand new motor for my boat will be here this Wednesday so excited buddy got a water heater issue though I think I have it resolved love the videos buddy

[@OutOnTheReef]

@foreverfixin Wow, captain. That is awesome , and what brand did you told me before that you get and how many horses?

Hell I figured you was put your mouth around it and blow 🤣🤣🤣 I always run my engine in a barrel. It help add back pressure so you can find any potential issues before hitting the water

[@OutOnTheReef]

@@kochykoo That is a good point, captain.That's why using a barrel is one of the best ways to test your engine
