One on top of the wear plate and one on the bottom of the wear plate. The bottom gasket is not in the kit. I was forced to use the original wear plate because the bottom gasket was stuck to the plate, and I did not want to damage the gasket. I was lucky that the original wear plate was still in good condition. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | GHmarine | | Colour | 18-3517 | | EU Spare Part Availability Duration | 2 Years | | Item weight | 330 Grams | | Material | Cast Iron | | Style | 18-3517 | ## Product Details - **Brand:** GHmarine - **Colour:** 18-3517 - **Item weight:** 330 Grams - **Material:** Cast Iron - **Style:** 18-3517 ## Images ![Water Pump Impeller Kit Replaces Mercruiser Alpha One 46-96148A8 46-96148Q8 46-96148T8 46-96148A5 46-42579A4 46-44292A4 46-48747A3 - Image 1](https://m.media-amazon.com/images/I/61F7yJm7AhL.jpg) ![Water Pump Impeller Kit Replaces Mercruiser Alpha One 46-96148A8 46-96148Q8 46-96148T8 46-96148A5 46-42579A4 46-44292A4 46-48747A3 - Image 2](https://m.media-amazon.com/images/I/71x0ttX2WcL.jpg) ![Water Pump Impeller Kit Replaces Mercruiser Alpha One 46-96148A8 46-96148Q8 46-96148T8 46-96148A5 46-42579A4 46-44292A4 46-48747A3 - Image 3](https://m.media-amazon.com/images/I/71Zx97yV3yL.jpg) ![Water Pump Impeller Kit Replaces Mercruiser Alpha One 46-96148A8 46-96148Q8 46-96148T8 46-96148A5 46-42579A4 46-44292A4 46-48747A3 - Image 4](https://m.media-amazon.com/images/I/711io2CoVaL.jpg) ![Water Pump Impeller Kit Replaces Mercruiser Alpha One 46-96148A8 46-96148Q8 46-96148T8 46-96148A5 46-42579A4 46-44292A4 46-48747A3 - Image 5](https://m.media-amazon.com/images/I/61P4rBRXGlL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked as it should *by J***L on 12 September 2025* Came fast worked as it should ### ⭐⭐⭐⭐⭐ Correct kit for a 1995 Merc/Mariner 90 hp *by D***O on 13 September 2021* Good quality kit, but you need two gaskets.
