I am big (290 pounds) and tall (6' 3") and I struggle a bit to fit inside the locker adjacent to the engine compartment on my surf boat. It is not made for people my size. It's no surprise to me that during the boat yoga sessions I drop a drain plug from time to time and it's nice having spares handy so I don't have to waste too much time getting even more contorted trying to get the lost plugs from under the engine!

Swapped all our plugs on a Mercury Marine 7.4mpi. Solid plugs. Work as expected.

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.

If you own a boat with a big block motor, you are going to need to replace these from time to time. This works great!

Replaced the ones with broken ears on my 383 Mag Stroker. Look and fit like the factory ones. Highly recommended.
