How To Correctly Use Flush Adapter?

- I was setting the water pressure to about half way. But I didn't see the "telltale" sign of water stream coming out from the back of the motor when I was running the motor. All I saw was water coming out from around the flush-earmuff, and from around the propeller. Is that normal? Should I increase the water pressure (knowing that I should not use full water pressure)?

- I saw that the engine temperature steadily went up from 100-degree to 170-degree (during the period of 4 minutes). At that point, I was afraid that I might overheat the motor; therefore, I turned off the motor. Did the motor not getting enough water cooling?

- During the sea-trial of the boat just a couple weeks ago, I saw the telltale sign of water coming out from the back of the motor. Therefore, I know that the water pump worked. I am wondering why the flush earmuffs doesn't seem to delivery the desired result?

- I guess one of the alternative is to put the motor into a water tank instead of using a flush earmuff. Where can I find a water tank big enough for a 115HP outboard motor? I measure that the water tank needs to be at least 21" tall and 24" wide. I have a feeling that a plastic container probably will not hold up the water pressure, right? Where do people get their water tanks for this purpose?

Thanks in advance for any info.

Thanks for the warning though. I will check the water temperature in the water tank next time when I need to flush the motor again.

I still cannot figure out why the flushing earmuffs cannot give me the desired result. May be I should have increased the water pressure to almost full pressure. But I don't want to risk damaging the impeller in the water pump. Moreover the small water tank is _much_ cheaper than the flushing earmuffs ($5 vs $30). Seem like I am better off using the small water tank instead of worrying about how to get the flushing earmuffs working.

Turn the water faucett on completely open, not 1/2 way. I don't know why anyone would want to run the risk of overheating an engine by turning it on 1/2 way.

Note that you will be putting pressurized water in to the impeller with the hose adapter. That may mask a problem with the impeller. Using a barrell isn't a good idea with a 115 HP engine. It will heat up quickly.

Keep an eye on the temperature gauge as you have been doing.
