Full StarFull StarFull StarFull StarFull StarGreat 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.

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.

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!
