hardhead, your not suppose to run the motor with the flusher according to the manual. I also was looking for that low intake flusher and found one through the local dealer but they want about 100.00 for it. So I think I will get a big tub and set the motor in it.
You can use the flusher on the port side of the motor, just don't rev up the motor and it will be fine.Sometimes i don't even start my engine, just flush to get any brackish water out when i go speck fishing close to the gulf.
Says right in the manual don't do it with the engine running.
Yamaha also wants you to run their oil, but not many do that either. I bet if you were to ask 10 different mechanics that 9 of them use the fluse hose and not the muffs. I've had several Yamaha's and have always used the flush hose on the with never a problem, but if you want to spend the money on the muffs i guess thats fine too, but either way is fine as long as you don't rev the motor up a bunch, which you should never do anyway.
Yeah there is always bad advice in the yamaha manuals. Who writes this stupid stuff anyway? I was just answering the guys question about a flusher. Right now I have the lower unit off an HPDI and I will hook up the hose to it and see how much water comes down to the water pump when its on the hose. I have also ran different yamahas that I have had on that hose. As of now I dont think its a good idea.

I think you will find a lot of water back feeding to the pump. Once the block is full, the force of the hose water will all be directed down the feed tube to the pump, as it has no where else to go except out the pisser. I've used the hose for many years, on many engines, and have never hurt a water pump. Just sayin.
