Fit Perfectly on Our MerCruiser 4.3L
We used this 5-pack of blue plastic drain plugs on our 1997 Bayliner Capri 1850LS with a Mercury MerCruiser 4.3L LH marine engine, and they worked perfectly. The fit was spot on, threading in snugly with no leaks or issues. They feel durable for plastic and seem like a solid replacement for the originals. I really like that the pack includes extras—great value for the price, especially if you tend to misplace one during winterization or maintenance. Installation was simple, and they sealed up the exhaust manifold and block drains exactly as expected. If you’ve got a MerCruiser setup like ours, this kit is a safe bet.

Cheaper made than Mercruiser ones
They are typical Amazon Chinese aftermarket parts but they work. Probably won't last as long as the Quicksilver or Merc manufactures ones. You might get by with replacing "O" rings on your old ones. I did find out I has some leaking when I replaced them.
