by Adam from Bowling Green, Kentucky on March 03, 2014
This seal kit isn't as hard to put in as you think, buy the spanner wrench, read a manual, and it's going to be just fine. I did the upper in 1.5 hours and it pressure tested perfect.

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.

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.

Q:
Is this the gasket for the screw where the gear oil goes in the lower unit?
A:
That is right. It is designated for the drain area where the oil enters the lower unit.
Q:
Does this come with the o-ring gasket?
A:
Yes, the plug and the gasket come together.
Q:
Hello, I have a 1995 Alpha 1 outdrive. Quicksilver P/N 19-47579 is about 1/3 too small for the hole in my outdrive. Is there an alternate larger plug? Thanks?
A:
Unfortunately, we do not have anything larger than this. We suggest posting a question on our Forum page. Thousands of boaters visit there every day and may be able to assist you in finding a housing plug that matches your requirements. The Forum can be found at http://forums.iboats.com/
A:
I have found another part number that may be the larger plug. Quicksilver P/N 19-32297 seems to be similar and is also called out for some Alpha 1 drives.
Q:
When I look up the part number for this item 18-3232-9 it shows quantity of 5 on all the other websites. Is this a 5 pack of plugs?
A:
Yes this is sold in a package of 5.
