Great OEM replacement
by Darryl from Decatur, Illinois on November 30, 2014
An excellent replacement to worn OEM parts. After years of routine service on my lower unit, the OEM drain plug became worn and hard to take off and put back on. This part assembly was a perfect fit for my Merc 225 EFI.

Missing seal
by Michael from Minnetrista, Minnesota on February 23, 2014
Either the picture for this product is misleading, or there was a piece missing from the order. The picture shows a plug with a gasket however, only the plug was sent (no gasket). Two emails to the customer service area regarding this went unanswered.

What's to say
by Scott from Chisholm, Minnesota on June 12, 2012
This does what it is supposed to do and that is stop the oil from coming out when in place and allow it to flow out when removed. Seems to work well!

Q:
Do these fit Mer 70Hp ser#08275667 can I get just the o-rings?
A:
There are no results with that serial number. Mercury serial numbers typically a letter, ex: 0B275667. Assuming that's what it is then you need part number 18-2375.


Q:
Will these work in a 1975 chrysler 75 75hp model?
A:
Yes it will work for your outboard motor.


Q:
Need a lower unit hydryolic plug for a 75hp Mariner any suggestions?
A:
We will need the serial number of the engine to cross reference the part.


Q:
Does this come with the o-ring gasket?
A:
Yes, the plug and the gasket come together.


Q:
Does this fit a Merc 25XD serial # 6634579?
A:
No you need 18-2375 from Sierra for your motor.
