🔌 Mercury - Mercruiser 19-889725 Vent Plug Sd@5: Genuine Quality by Mercury - Mercruiser Review

Based on my experience, this vent plug is simply amazing. It fits perfectly and is very easy to install. The quality of the materials used is outstanding and it is built to last. I noticed a significant improvement in the performance of my engine after installing this plug. The threads are well-made and the design is very innovative. The only downside is that it is slightly expensive, but the benefits definitely outweigh the cost.

Works as advertised. A bit tricky to install but I'm sure it's necessary for them to stay installed while running. They have been installed for over a year and still work great.

I have a Nitro z20 with Merc 250 proxies with a 25 pitch Fury prop. These plugs completely killed my entire shot, I could barely hit the plane. But once I was on the plane, they didn't seem to affect anything. I take them out and come back with no traffic.
