## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by V***I on December 10, 2024*

Fits my motors

### ⭐⭐⭐⭐⭐ Fits perfectly on my Mercruiser 4.3L, one day turn around
*by J***M on November 2, 2023*

I started winterizing my 4.3L Mercruiser before our first Artic blast. Of course, one of the plastic drain plugs snapped when I took it out. Hello Amazon ... glad to find these plugs and was really pleased to receive them about a day after I placed my order (coincidentally the day before the Artic blast arrived). Will see how they hold up but for now I'm well pleased (and I now have (4) spares ... just in case I need them next year).

### ⭐⭐⭐⭐⭐ Works great
*by W***Y on December 17, 2022*

Product is great , but the color is a more dark blue to a purple. it would have been better to be the baby blue color(like original) so you can see it better under the engine but they do work good just be careful threading them in, you could cross thread them easily , just sayin
