How to flush your Yamaha outboard correctly!

Properly maintaining your Yamaha outboard motor is essential for long-lasting performance on the water!

In this video Aaron goes more in-depth on how to flush a Yamaha motor using the cold flush! The USA and the majority of the places globally use this type of fitting. Australia does not and as such us Aussies have to use an adapter. They're $4.5-$6. The cold flush fitting back fills the water gallery's throughout the head, so it gets both sides of the thermostat and then goes down with gravity through the impeller. An impeller pulls water up from the bottom when turned on, as such, whilst on cold flush do not turn the motor on as it will starve the impeller of water. It's called a cold flush for a reason! Simply attach the adapter to the flushing port, connect a garden hose, and turn on the water while the engine is off. This process helps remove salt, sand, and other debris from the water jacket, ensuring a clean and healthy motor. Give your motor the TLC it deserves and enjoy smooth motoring for years to come!

Should be on ALL outboards. Make it an industry standard.

The worlds biggest boating controversy! Love your work mate, cheers 🍻

Couldn't be clearer. Love your emails. If you open a branch in the UK I'll be your first customer

Just bought me a little 9.9 Yamaha. Best motor I think I’ll ever have🤷🏻‍♂️

This is too funny! I’ve always knew of this way but just thought it was a “last resort” if I don’t want to piss off my neighbors now I know I’ve been doing it wrong! Thank you man now I have to convince my grandfather 😂

I actually flush my Yammie with the flush port and the muffs. Never had an issue with the pressure using the muffs according to the pressure gauge on the dash. Town water pressure here can hit 90-100psi though.

I add a little bit of dawn dish soap then the hose.

I just love getting back at my neighbors after they have partys every weekend last year😂🎉

Nice. Should be made mandatory for all manufacturers.

I thought this method does not allow the thermostat to open so you only flush half way.

Brisbane Yamaha. Thank you. Learned and recently applying this the way you explained with the hose and fitying. Happy to hear it from you. One question though: I have to do this in the marina tied to the dock. That is, boat is on the water. Motor tail comes out of the water with full up trim. Should I flush with trim up or keep tail in water for most effective operation.

I actually bought my F70 yamaha because of "Boats Boats Brisbane!" and their walk around of that motor

My Yamaha 130 Saltwater series has this flush port. I've been using the muffs to flush it so far. I''m curious now as to giving it a shot after running the motor in saltwater.

Just checked the owners manual, and yep, should be good to go.

[motorcycleislife]

Can you run the engine while its connected that way?

[joshuasteinhoff]

Hey mate I haven’t checked as I’m not at home but does this also apply for older outboards? I believe mine is in the 2005-2007 range

[ericsharp]

Great video thanks for explaining. Quick question, when I flush my 2023 90hp Yamaha this way I get no water out of the tell tale. Tell tale pees like an 18 year old after 4 pints when its running though. Is this normal? Cheers!

[stoweman]

I was told that flush port is only good if the motor is still hot, otherwise you should use the muffs to open and flush the thermostat.

[PerfectParking]

I dunno on the outboards but in the jetboats the engine HAS to be on prior to starting the water or you run the risk of flooding it

[jimmykipper]

Good info. How about adding some salt away into the supply towards the end?
