Another note - not all engines require those muffs for flushing. For example, Honda outboards have a flushing tee built in that takes a regular garden hose thread...
Thanks to all for the input. I ordered from SIM.
In my experiences...... newer motors don’t need to run , to completely flush the motor. Many motors will over heat if you try running them with lower unit ear muffs. Also .... newer motors have connections for water hose directing to motorI'm trying to find the "ear muffs" that attach to hose and go on the outboard water intake to allow starting motor on land. Can't find....don't know what to call this item. Help!

I'm sure that this is generally speaking common knowledge, but for anyone new reading this NEVER NEVER NEVER run the motor using only the garden hose flushing port. Flushing it with the motor off is fine, but if you attempt to run the motor with just the flushing port you will burn up your water pump in well under a minute and possibly do extensive damage to the motor.
The only way I would even consider doing it is if the manufacturer explicitly states that it can be done (and none do, to my knowledge), and even then I'd be leery of doing so.
I have said this before and a Yamaha dealer recommended. I run in spring and fall with the hose with no issues at all. I winterize it at idle and run it in Spring before launching. Someone said you will mess it up. Sorry but you are wrong. The bottom gushes and the highest point in the cylinder head pisses Cool water. Yes the manual says not to. That is because some would run it at 4500 in their driveway. Been doing my 150 with no issue.I'm trying to find the "ear muffs" that attach to hose and go on the outboard water intake to allow starting motor on land.

If you are looking for a flush after running I use the port engine off motor up. Two minutes and the pee water has no salty taste. For running I could not get the muffs to seal and got inconsistent pee. Hose fitting= no issue. 2011 150 YamahaI'm trying to find the "ear muffs" that attach to hose and go on the outboard water intake to allow starting motor on land.

I know of several outboard motors , running at idle speeds that ran hot , and had to replace impeller and housing. These motors where at different locations , so it wasn’t a water pressure issue at the source.I have said this before and a Yamaha dealer recommended.
