How To Properly Flush Yamaha Marine Engines. Specifically Jet Propulsion Boats. Yamaha 210 FSH Sport

[@ChristianGrest]

Solid info! Thanks for running through the process to help folks out.

[@THEFSHDUDE]

My pleasure, Thank you for watching 🤙🏼

Hello, Just had a great day on the lake. I got home and hooked up the house and nothing came out the pisser. Water was coming out through the pump though. I am now receiving an engine overheat alert. Any helpful comments and next steps are welcome. Best, Jeff

[@THEFSHDUDE]

This is usually caused by low water pressure from the hose. Try hooking up to a higher pressure spigot somewhere else to test.

Have u done any engine mods? Like a ribbon delete or air intake? I have the same boat but need more speed

[@THEFSHDUDE]

You won’t get much out of these motors. They are the TR1s. Designed for efficiency not speed. I’ve seen people drop thousands and only get 4mph. Not worth it. The smart tabs got me 1-2mph top end.

[@JohnnieCash305]

@@THEFSHDUDE thx I will just leave it or just do an inexpensive ribbon delete

[@jonathanbealand6249]

May be a really stupid question but first time boat owner and just got our 2021 FSH 210 sport. Question is I understand water can’t be introduced to engine until engine is on etc when cleaning..but what do you do when launching? Do you start boat before you put it in water from the trailer? Hoping you can help with the best practice on this. Again apologies for a dumb question but total beginner here.

[@THEFSHDUDE]

This only applies to flushing. Do not start the boat before putting it in the water for launching. Start it after it is in the water. Otherwise you’d never be able to stop your boat if you think about it. Flushing forces water into the cooling system with or without the engine running. The water intake for the engines only forces water when the engines are running in the water. If you run the engines out of the water without using the flushing ports you will overheat them.

[@BryTunesMusic]

Thanks! that was cool to see how loud or not it was going to be when you throttled it up outside the water - and it seems they have made them a good bit quieter in new models? Thanks again - I'm on the 2022 list for August

[@THEFSHDUDE]

You bet!

[@juanbolivar35]

2022 for August?! wow how long do you have to wait?

[@BryTunesMusic]

@@juanbolivar35 I'm talking about a 2022 model boat being received in Aug of 2021, which is starting to happen now - but is not going to happen for me anytime soon

[@drakelaughlin7333]

Hey brother when I clear out the water at the end I get a whining/screeching noise. Any idea?

[@THEFSHDUDE]

Honestly I’d have to hear it. Email me a video and I’ll see if I can hear what’s going on. [e-mail]

[@seancartwright7402]

where did you get the connection for the end of the hose?

[@THEFSHDUDE]

Link is in the description. You can also use this one amzn.to/3vC3v8I

[@GeneGore23]

Does it matter if the clean out ports are closed or open during the flush?

[@THEFSHDUDE]

It does not

[@morsalean1]

I’m not getting any water coming from the side. What could be the problem?

[@THEFSHDUDE]

There could be a few problems first being water pressure if you do not have enough water pressure from your hose It won’t come out the side next would be clogged ports sometimes the port gets clogged by insects and lastly, you could have an issue more major like engine issues the first thing I would start with the hose pressure and go from there.

[@juanbolivar35]

Thanks!.... questions, is it possible to use a "Y" to connect 2 hoses at the same time and flush both engines?

[@THEFSHDUDE]

Yes, but unless you know your pressure is enough to support this then I highly suggest doing it by the book. There is a certain pressure range that needs to be supplied and a certain RPM you should keep to properly flush and cool the engines. I personally dont want to take that chance. Plus, doing each engine individually lets you hear how each one is running compared to the other. If they are both running problems are easily hidden by the other engine noise. Like I tell everyone else, do it by the book and do it right for longevity of life. When you cut corners you run the risk of prematurely damaging your boat. That goes for everything including washing and service.

[@firetaz39]

Dude.. Where did you buy the spare tire mount for your trailer? I ordered one like that and the frame brackets were not wide enough to mount to bracket.. Also, did you install the vertical gide poles yourself? If so, where sourced?

[@THEFSHDUDE]

That spare tire mount comes with the trailer stock from the factory for the FSH 210. The guide poles I did myself. Here’s the link amzn.to/4b2R58E

[@khanhle-vu2hh]

My water does not come out of the "pilot" but it come out in the muffer and i flush ? Is that ok ?

[@THEFSHDUDE]

That means your water pressure is too low.

[@dashcamchronicles7956]

Great job and explanation! Only suggestion, save your knees and add a valve for the hose at the end so you don't have to go to the spigot each time.

[@THEFSHDUDE]

I have, if you watch my newer video on flushing you will see I added that a while back. I appreciate the effort though 🤙🏼

[@itr0863]

thank you so much for the video! in regards to docking in salt water. is there any maximum amount of days for jet boats to be docked in salt water?

[@THEFSHDUDE]

Thank you for the support. I am not sure from personal experience but I have heard that people dock them full time they just make sure to pull it out of the water and do a cleaning about once a week.

[@yandini85]

Nice explanation bro 👌 still on the waiting list for the FSH 255 sport E 👍

[@THEFSHDUDE]

That’s going to be a fun boat!!

[@mgweir3252]

Flushing is important when running in salt water. I only do fresh water, so it is not as important. I just have to make sure all the water is out for the winterization process.

[@THEFSHDUDE]

Remember to still flush in fresh water too. Sediments and organisms in the water that sit can also cause issues after a while.

[@ralphv.5026]

Does it matter if you do this with bilge pump off?

[@THEFSHDUDE]

No, the bilge pump is for standing water in your hull. This is for flushing the internal components of your engine cooling system.

[@ralphv.5026]

@@THEFSHDUDE got it. Thanks. The other day I flushed the engine s and steam was coming out and water dripping from the back was hot. Few days later I flushed them again and no steam whatsoever. Do you know why that could be?

[@THEFSHDUDE]

@@ralphv.5026 that’s normal, the water is hot because it’s absorbed the engine heat. That’s how your motors are cooled. Sometimes it steams sometimes it doesn’t .

[@rezanaderian4827]

I think I made mistake last time and water stocked to the engine and when I used the boat today it was making so much noise and for 30 minutes full speed didn’t go over 10 after that it’s was better and again same thing happened. Do you What should I do to fixing the issue? Thank you

[@THEFSHDUDE]

I hope you didn’t get water in the engine and if you did you could possibly have damaged internals. Pull spark plugs and turn the motor over to see if water sprays out. Also check your oil and see if it is “milky” Hope everything is ok 🤞🏼

[@deancoburn944]

Not using salt terminator to flush?

[@THEFSHDUDE]

Not in this video.

[@4dLoveOfSoccer]

I learned the hard way you got to rev the engine after shutting up the water hose. make sure you do otherwise water stays stuck in there and corrodes your sensors. Had to replace both O2 sensors $185 a pop! ouch!

[@THEFSHDUDE]

That is correct, the blow out is shown in the video just for that reason. Thanks for the comment. Never let water rest anywhere, not just the engines.

[@timsmith8391]

How far do you take her out

[@THEFSHDUDE]

Over 40 miles off shore

[@dustincaldwell2049]

Hmmm mine doesn’t flush through pissers during clean out. Never has. 🤔

[@THEFSHDUDE]

That’s an issue, you may not have enough water pressure or high enough rpms?

[@anthonyjannace4410]

It's not an issue; if the boat is not level and you have low water pressure, such as a well, it won't piss. As long as it is pissing during in-water operation is critical. Mine does the same because I am on well water, and my boat sits on a lift, not level.

[@Danny-qi4lp]

Great video. Thanks.

[@THEFSHDUDE]

Glad you liked it!

I just wanted to make a one time donation but it looks like it’s only set up for reoccurring monthly donations???

[@THEFSHDUDE]

Yeah, that’s the only option they offer. If you know of a different site please let me know and Thank you for your support 🙏🏼

[@GriddleFoodNetwork]

🤙

[@THEFSHDUDE]

Thanks.

[@serega4087]

Engine ran like 45 not 15 sec after you shut off the water 😅

[@THEFSHDUDE]

Lol obviously, I was shooting a video by myself and doing the procedures all at the same time. If you pay attention the engines did not overheat.
