This driveshaft housing retainer replaces OE#: 816811 2 and fits Mercruiser R, MR, Alpha One Generation I and Alpha One Generation II sterndrives from 1972-current.
I bought the Sei Marine Products retainer for my MerCruiser drive shaft housing and it fits like a glove. Installation was straightforward, and the quality is evident right out of the box. It's saved me a lot of hassle and I feel more secure out on the water now!

Not a perfect fit for my model
I had higher hopes for this product. While the Sei Marine retainer looked robust, it didn't fit my drive shaft housing as advertised. It was a bit frustrating trying to make it work, but eventually, I managed a workaround. Just be sure to check compatibility closely!

Decent but had a hiccup
The retainer works well with my MerCruiser, but the shipping took a bit longer than expected. Once it arrived, the installation was easy and it seems durable so far. Just wish the packaging was a bit more protective.
