this was quite a bit more expensive, but it's well-made and it has a cover on the inlet so I like it

Got a mercury 115hp 2023. The quick connect doesn't fit snugly, keeps coming loose and coming out. More trouble than it's worth.

Easy to install. Just take out the old plug and screw in the new one. Quick couple makes rinsing out engine easy and fast. Downside is this seems way overpriced for two little pieces of plastic! But looks like they have a monopoly on the market.
