2012 Yamaha 150HP

When I flush the outboard, I'm getting no water out of the telltale when I put the muffs on it. Is that because it takes a few minutes to warm up before water comes out of the tell tale or do I need to flush in a bin? Water comes out of tell tale in the ocean but never remembered to check how long it takes to start coming out when I stick it in the ocean.
All ideas/help appreciated. Thank you

Are your muffs the double
Are your muffs the double ones? make sure your tap is turned on full and even squeeze them on the motor for a minute and see if it comes out. I had the same problem and changed to the double muff and works fine now with the tap up full. When down at the boat ramp the wash down station pressure is shit and i have to squeeze them on for a minute before it starts flowing.

I found with my yam 200
I found with my yam 200 sometimes i have to increase the engine revs a little to get the water flowing out telltail and then things are all good

Yamahas don't seem to like
Yamahas don't seem to like muffs much. You need a really good seal for them to work.

If youve got the flushing
If youve got the flushing attachment(the one that you use with out running engine) then you can prime engine using that for a few minutes then put muffs on and start engine.
The bigger engines (mostly the 6 cylinder ) need alot of water so having all the water jacket full of water to start with helps.
Also as stated above the dual inlet muffs work best.

Yea my yamaha 115 is the same.
I need to have the tap full on and give the muffs a squeeze to get the water flowing....Once it starts flowing it's normally fine.
Once the "Overheat" alarm went off even though the tell tale was flowing well, so adjusted the muffs and squeezed them again and in no time it was running cool again.
The double flow muffs sound like the go though !!

Running boat 2-3x per week
Thanks guys for suggestions.
I think I read on here that flushing is not as important if engine gets used very regularly, such as the 2-3x per week that I'm using it. Is this true?

Probably not however I would
Probably not however I would still flush it each time to keep the waterways clear of salt when they dry out whilst not being used.
Especially with the thermostat which could stick if salt is allowed to build up and dry in there.
I could be wrong but that's my thoughts.

water
My understanding is with just muffs on shouldn't rev as stuffs the impeller , either the heat makes it brittle or being rubber can get tacky and stick
I would recommend flushing I never worried too much with my 75 but only a few months ago taddle tale stopped working pulled the water jacket off and was a clump of dried salt/ corrosion ? Just a white clump blocking the outlet , cleaned up the rest of the jacket as had lumps of corrosion ect almost growing on the inside
A bit of fresh water cheaper and easier than gaskets and parts which I found to be bloody expensive
Mind you is getting on towards 15 year old donk so won't happen overnight but next donk will be flushing religiously

Not enough water flow , would be looking at a new system to flush to prevent any other drama's

I have an F115
Using an ancient set of muffs, the good old strong type with a good seal, usually takes 10 secs at idle to push out of the telltale . Regular flushing is always a good idea--some people go verboard with it, frwak out if they can't flush every time--if you are camped remote you may have to go a month without flushing, but she is running every day, staying wet. I may flush mine with Saltaway this year after returning from the annual trip, see what the flushed water looks like.
