I have an alpha and a bravo coupler laying around and I am trying to decide what to do with them. Both are supposedly good, but I have never used them. The alpha style coupler came on a boat I bought with a 7.4l/bravo 3. The engine was older than the boat and I believe it was around an 88-90 model (the short period when the 7.4l came with an alpha one drive) and the bravo couple was a used one I bought for a used engine I purchased to replace the older model 7.4l in the boat. Supposedly the bravo couple only had ~100 hours on it. The second engine I purchased turned out to be no good, so eventually I purchased a correct used 1997 model 7.4l complete engine with about 400 hours on it.
I am debating on swapping the couple on my new (used) engine with the one I have as it has a quarter of the hours on it and listing the alpha one couple online for sale. The alpha coupler looks like it has rubber pieces on the back side. The bravo couple looks similar but it looks to be silicone rather than rubber. I have looked at different ones for sale online and see a wide range of different pictures, some very clean and some look to be in worse shape than mine.
The first picture is the alpha coupler, and the se3cond is the bravo coupler. They are pretty dirty from laying out the shop for a couple years.
