best drain plugs on the market for marine engines. Brass into brass and do not forget some water pump impeller housing are brass where the drain plugs go into. Also the best thing about these are you can put a long extension socket on them for the reach. Can not do that with a wing nut drain plugs. So many of the wing nut drain plugs get stuck and can not get out with fingers or they are hard to reach by hand. Also when you have 2 different metals against each other - that causes corrosion. These are perfect for block drains as well and do not need a oring to seal (never ). On the wing nut drain plugs you are counting on a thin oring to seal against water leaks as well.
Brass into brass will not corrode.

I'm at my wits end I think!! I've burned myself with hot screw drivers hot water (heat draws the water out) ect. The plug is just getting more and more mangled as I go....I'm getting nowhere. Think I might save time just pulling the whole cool fuel unit off! It needs to be worked on not upside down and barely in reach. I'm going to have to get it on the bench to do this by the look of it. Or should I try the EZ out way?? Mercruiser should have done it right and used brass plugs that are more durable. But then they wouldn't make money off stupid plastic plugs year after year. I'm in the process of ordering new ones from Michigan Marine (Harding).

if hard to get out or reach Just take a long blade screw driver or pin punch or thick long pic and break it apart to fail out. ONLY hit the plastic so you you not damage the threads or the portion the plug screws into. Use a hammer against what ever tool you are using to break it apart. Also an easy out always works but not all the time depending on reach and so forth. Every year I have to extract about 20 to 35 of these as most do not know they should be changed out every 2 to 5 years. Or when an engine is overheated or been running hot.
