Hey, when your aging brain gets to this stage - you take whatever it gives you {:>). Good luck on your inspection! Ready for you to get this out of your system and come back to the dark side.

Heading to Louisiana this weekend. Checking out the lead removal solution that I finally got to use (flying again!). This trip will give me over 16 hours using the stuff, so will likely pull a plug when I get back to see its condition.

Subject: [FlyRotary] Re: 13b Water Pump: Plugging Bypass Hole

I used a NPT tap - it was either 3/8 or 1/2" dia (its been over a decade).
I simply tapped it for a threaded aluminum hex nut plug of that diameter and
screwed it in tightly and its still there after over 10 year of running.

Not bad Ed. I'll give you full credit in consideration for your aging brain :-)

BTW, a good log and search engine makes up for that. Imagine how I know this :-)

From my log:

Tapped the bypass hole in the water pump housing with a ½” NPT tap. This worked pretty darned well. Installed an aluminum ½” pipe plug, with just a bit of high temp RTV on the threads.
