- Опубликовано: 24 фев 2023
- On this video I want to bring to all of you, a variety of tests I’ll be running on different Yamaha motors (starting with a F-150) to find out if running the motor with the top hose flush adapter will damage the impeller for lack of water and running it dry ( "I’M NOT TRYING TO TELL YOU WHAT TO DO". "THIS VIDEO ONLY SHOWS MY OPINION BASED ON MY OWN TESTS"

I've been doing it through the hose for many years, in different f150s f225, f250. Never had a problem.
Perfect, and thank you so much for your comment and opinion on this issue, feed back like yours are very helpful and helps a lot of people.
Take care. 👍🏻🙏
I appreciate people like you doing videos like this. I just picked up a Suzuki 150. And I've been running it for approximately 4 to 5 minutes at idle while I had the hose hooked up to the port. Then somebody told me you can't do that. And I say why the water pressure is the same. But your video was very, very specific and self-explanatory. Now I feel much safer. But of course, my last engine didn't have a port old Evan rude so I didn't have a choice. I used the ear muffs so this one's a little new to me. But Suzuki says I don't have to run the motor at all, which is kind of nice.
Thank you for your comment and for participating. 👍🏻
I happened upon this video as I was about to embark on fixing my own engine’s overheating issues. Thank you so so so so much! I have always flushed from the top and after watching so many videos in the recent days I was getting very nervous that I did damage to the engine by doing so. I understand, this is not your endorsement to do it, and Yamaha suggest you don’t, just glad to see your test. Thank you very much
Hi Five, thank you for. watching and participating with your comments, it really helps. I think tonight and /or tomorrow I will upload a new video update about this same issue, in an attempt to answer a lot of questions received. Stay tuned. Take care
More good information, thank you.
Hi Ezra, glad it was useful. 👍🏻
Guoooo amigo que buen video acabas de hacer, buena explicación y un tema del que mucho hablan, gracias por compartir tus conocimientos, yo en particular e aprendido mucho de tu experiencia nuevamente gracias por eso video
Gracias amigo Yanisvel por estar siempre presente. Pienso que este video podrá aclarar muchas dudas. Un gran saludo 👍🏻
Saludos cuídate estamos es contacto
Great video 😊
Thanks for watching, it really helps.
One doesn't have to remove the LU to verify this, just watch for water coming out of the intakes, it can only do that if it's flowing backwards through the pump.
Hi Donzi, yes indeed, however the objective of my video was to show those who doesn’t know the physical and visual evidence of the water flowing from the water tube directly into the water pump’s water outlet/impeller
Thank you for watching.
Thanks for an informative video on this. I've been doing it thru the hose for a long time and my 2007 Yamaha F50TLR has not been damaged. The only thing is, I've been letting the engine run, after running in saltwater all day, for 5-8 minutes which I hope is not hurting engine. Please let me know if I'm doing this wrong. Thanks my friend for your knowledge. Steve
Hi Steve, no, you’re not hurting your motor letting it run for 5-8 minutes of flushing through the top adapter, as you can see, there’s is plenty of water/lubricant, getting to the impeller. Thank you so much for watching and for stopping by. Take care 👍🏻
@@us4marine Thank you for reaching back out. I do respect ALL your videos. They're full of knowledge and people should respect them and also watch them. Steve
Burns up impellers , I fix them all the time . However like you said low rpm and for less then a minute is fine but never run for long or rev up on the flush adapter . If running long time u need both top and ears hook up
Yeap you got it. Take care.
What do you mean by need both top and ears hook up? I’m planning to run my motor on its trailer for 5-10 minutes..
I use both top connection and bottom ear muffs too. Maybe not necessary just for a quick startup on idle but extra precaution on my part. Thank you for this informative video.
Great video, you are a wealth of knowledge thank you for this. I have one question maybe you could help me understand with this same engine. Mine is a 2013 F150. After being used in salt water I flush my engine after every use. When I connect to the flush hose and run fresh water I never get water coming out the telltale port like when its running. Is this normal? I always think its better to use the muffs and run the engine to flush instead of the hose? What is better? Thank you!!!
Hi Wol9, this is very common on some of these 4 strokers, however is not that common on the F-150, do you have good water pressure on your garden hose? If water comes out when running with the lower flush and not with the top flush adapter and if you have good water pressure, I can only think of the pressure relive valve, some people in the industry call it "Poppet valve" and is this cover right behind your oil filter with 3 #10 bolts. This valve is spring loaded and it needs very good water pressure to push the plunger. But if you’re getting water flow on your side indicator with the bottom muff, I wouldn’t worry too much about it. Now, if you want to make it pee with the top adapter, increase your water pressure and that should do it. Hope this helps. Take care and thank you for participating, your opinion matters. 👍🏻
It really doesn’t matter, both ways will do the job, but remember if you doing it from the top with the engine not running, make sure the block is warm enough so the thermostats are open and you’re getting fresh water pass the thermostats and on the other side of your cylinder head.
I was getting nervous with the research i was doing since i always rinse my Yamaha 250 through the upper adapter. I am going to take off the lower unit and see if the impeller has any damage but i haven’t had issue. Might start using the muffs since that’s what yamaha recommends though😅
Hi Ian, let us know what you find and more important how many hours or months since the last time you replaced water pump.
Thank you for watching.
During winter season here in east coast, can I remove the lower unit and keep it in my basement for the whole winter?
Yeah, I always flush my motor from the top port with no problem at all.
Thanks for the info.
Hi Bean, Yes you can, but what would be the advantage of doing so? Can you elaborate more on this? Thank you for watching and participating. Take care. 👍🏻
@@us4marine -I winter my boat in a marina so I would rather install a new impeller at home and keep it for the winter.
The impelar pumps water up, your pushing water down in the opposite direction to the impelar, I presume the idea of top flushing is to allow you to do this is whilst it's still bolted to the transom in the water.
When water is fed from the top, the impelar is going to try and reverse the flow back up into the engine, could this cause overheating issues if the pressure was equalised and the flow is stopped or slowed?
Hi NJ, thank you for watching, your opinion and comment is very appreciated.
The intention of the video is to show that if you run the motor (at idle) while flushing it from the top, the impeller is definitely getting lubricated and cooled with large amounts of water, that’s all. The pressure couldn’t be equalized due to the water intake screens below the water pump being uncovered. So, there won’t be any back pressure, overheating, and the water won’t be stopped or slow, by running water from the top, the flushing procedure has not changed at all, and eventually water will get to the power head through the rear connection on the engine block between the cylinder heads. The only thing added in the procedure is that the engine is running and the impeller is being cooled with plenty of water.
Thank you for the advice. I'm having an issue with my Yamaha F150lb, and wonder if you know what it might be. Motor starts up fine. Runs good at high speeds. If I reduce the speed to just cruise around it will die randomly without warning. Motor will start right back up and run fine for awhile (maybe 5-7 minutes) and dies again. When docking, motor idles fine, but will die while in gear idling into the the dock. Starting it back up is not an issue. I'm open to any suggestions. Thank you.
How old is the motor (year) and how many hours on it.?
@@us4marine Not sure. I was told it was a 2019. The boat actually belongs to a family member and I just take care of it and get to use it. The tag on the motor mount says F150LB 63P L 1210952. I will have to check the hours the next time I go up (the boat does not get a lot of heavy use). I was on it a week ago. It ran good, but then shut off without warning. Really strange. Feels like someone just turned the key off. Starting it back up was not an issue. I was not in a turn or low on fuel. Other than the shutting off, it runs smooth. Thank you for you response.
@@xcbcm I had that issue with my f115, the linkage had moved slightly at the motor end. Luckily the paint marking showed where it should be.
So when you just turn on the water with the engine OFF, it won’t discharge water out of the discharge hole also known as peeing? Because when I hook my hose up with engine off, the tell tale doesn’t pee
what about that thru flush hose thermostat is not open , so water does not go thru all of head of engine?
Hi Jedi, correct, that’s why I tell all my customers to let the motor reach it’s running temperature in order to wait for the thermostat to open, so water can flow through the exhaust side of the cylinder head. Now if you’re referring the water flow while I was testing? No, water was not flowing to the any part of the block because the lower unit was off. The only intention on this test was to show the impeller is getting plenty of water when using this flushing method.
Hope this helps. Thanks for watching.
Ese error lo hacen mucha gente yo lo conecto 10 minuto apagado abajo siempre pero muchos lo prenden arriba y abajo q Bueno el video porq Ayuda a muchas persona q comenten el mismo error gracias por tus video Pete
Un saludo Rene. Gracias 👍🏻
I use the top flush when I don’t want to annoy my neighbours but when I want to do a good flush with salt away I run the muffs so the thermostat opens up fully.
I’m not sure what’s best
Hi OGMoses, you’re doing both great, one is probably more thorough than the other. Thank you for watching. Take care 👍🏻👍🏻
I have been flushing these mothers form the introduction of the top flush back early 90’s on all brands , merc ‘ omc , Yamaha. Common sense good water pressure.
Hi Sean, PRECISELY my friend. Thank you for stressing such important factor. Take care and thank you for watching. 👍🏻
no you nighter could or should.... i dont know about your experice but i burned two when i tried ... if you keep the engine running a little bit longer and empeler is new it will burn i have tried that 2 time and failed both times>>>>>>>
Correct, reason why I explained it clearly if you see it at the very beginning of my first video of the 2 I made on the same topic. Thank you for watching.
But you are forcing water against the normal flow of the impeller, correct?
Yes, but when flushed from the top adaptor, the water send to the impeller it's only to keep it wet, there’s a “T” at the engine block that splits water to both, the impeller and complete engine block. In other words, when flushed from the top the flow of water going to the impeller is not relevant to keep the engine cool.
How about having the engines turned off and turning the impeller manually?
Hi Tat, Thank you for watching. I don’t really understand your question on how you’d turn the impeller by hand? Maybe there’s something in the video I said that lead you to a wrong conclusion?
Please if you could explain a little better what you mean. Thank you again for being part of the channel. Take care
The prop isn't connected to the impellor, if that's what you mean.
So, don't run the motor when flushing from the top hose. Am I right?
As I said on the video. Yamaha DOES NOT recommend it. The reason of the video is the show, that if you do, the impeller won’t get burned as lots of water is raining on top of it. It’s entirely up to you. Thanks for watching.👍🏻
@@us4marine Many thanks for your advices, sir. Much appreciated.
What does the manual say?
Hi Fishing, there is an easy answer in the first 60 seconds of the video, ESPECIFICALLY addressing your question. Check it out, is there, is very very clear. Thank you for participating and for watching. Take care
when you drop the lower unit the pump comes with it so I don't know what you are talking about
Hi Bob,
Let me try this on a different angle and maybe you can understand. The idea of the video is to show it’s ok to run your motor with the water connected on the top adapter and to show that by doing this the impeller will be receiving plenty of water and won’t get burned, right? There is no any pressurized water flow (as you mentioned) because with the lower unit installed, there is no a dead end for the water flow, why? because once the water gets to the impeller it keeps flowing downwards through the black plastic water intake screens located right UNDER THE PUMP, thus avoiding the pressurized back flow you mentioned, it’s an absolute free water fall. There is no need for the impeller to send water up because the top adapter “T’s” right where it connects to the engine block, and so supplying plenty of water to the mid section and the engine block. Hope this helps.
Thank you for participating.
Your right, you don’t know. This video proves the pump would be lubricated. Great video! Thanks for the info!
@@arubanjames Thank you Aruban, I really appreciate your opinion, you’re are an important part of this channel. Take care.👍🏻
Yamaha has now changed there mind and now says you can …keep in at an idle….only
Yeap, guess they couldn’t disagree much longer knowing what a huge amount of water was reaching the impeller. 👍🏻👍🏻
Thank you for your comments and for watching. Take care.
Is this serious, what you been they change their mind?
Do you see any water coming out from the tell tail in this test?
Hi Born, no there is no water from the side indicator on this test, because the lower unit is off, so the water does not find any blockage when reaching the water pump (absent on this test), to increase water pressure enough to get to the indicator. Example: if I had put my hand at the end of the mid section water tube to restrain the water coming out, water would’ve come out the indicator immediately. Hope this helps. Thank you so much for watching.
The water goes the other direction
Hi Bob, Can you be a little more specific? What way is the water going? On the melted housing, mostly all Yamahas impeller housing are somewhat melted around the inner walls when you remove the impeller cup, this is very common and the reason why the housing, should be replaced every time.
Haha😂
👍🏻
I melted my impeller hosting doing that
Yamahas melted housings is very common even if you don’t flush your motor at all, just with regular use you will find the inner walls meted when servicing the pump.
