Mercruiser drain plug
by Dennis from Lostine, Oregon on June 01, 2017
I like the plastic plug because, after repeated uses there is no risk of stripping threads in mating part. They last several seasons, but I always carry a new spare.

Q:
Can you tell me the tread size and count for this plug? I need to retap a hole with bad treads?
A:
According to our sources, the thread size is 1/2 x 13. However, the threads on this drain plug are deeper than the conventional design.


Q:
I have a 4.3 L V6 Mercruiser engine which part should I order?
A:
We will need to know engine serial number to confirm drain plug.


Q:
I have a 2002 mercrusier 4.3 MPI 220 HP sn. OM320204, will thsi fit ?
A:
Yes.


Q:
Will this fit a water drain plug on a 1988 mercruiser 3.0l?
A:
No it will not. According to Mercury's parts list the drain cock assembly located at the cylinder block is 18-4218.
