Right Parts!
by William from Ogden, Utah on July 17, 2012
Call center "Adam" @ Ext:106 did a great job finding the right parts I needed to have the mechanic rebuild the lower end seals. Motor is not easy to find parts for except thru IBoats.

Lower Unit Seal Kit.
by Robert from Belleville, Illinois on August 25, 2015
The seal for the gear shift shaft appears to be the same outside diameter as the Mercruiser part, but when you press it into the gearshift bushing, it cracks the plastic bushing housing. Then you have to buy a new bushing housing to replace the old. When checked with a micrometer, the seal in the kit is just slightly larger than the Mercruiser part. In addition the new seal is metal, while the Mercruiser part was encased in rubber, giving it a little more "give" when pressed in place.

Seal kit Ordering procedure.
by Dennis from Spokane, Washington on June 11, 2013
Your Product is good. What happened to Parts Finder? It was a very useful tool for me. I asked for a part and it asked what it was for, make, model, year, serial number, horse power, etc. I had to go to another parts place online to get parts for my Evenrude. I needed coils and points. I couldn't figure out your complicated ordering process. Looking forward to doing business with you again, if I can figure out how to order parts. Thank you. PS I'm not the only person who feels this way.

seal kit # 18-2653
by Richard from Williamsport, Pennsylvania on August 12, 2014
Did not come with exhaust seal as pictured in add. I have requested the seal by part number but it seems you need a bar code which I do not have. You already have my order number and package part# 18-2653. The exhaust seal is pictured in your pictured add. Please send the exhaust seal ASAP. That seal is needed to complete rebuild which now I'm behind in the rebuild process. Thank YOU, Richard

Q:
Will this fit my 2002 "L" 120hp drive lower unit?
A:
This goes to a Force 120 1995-1999. We don't pull up any records of the Force 120 after 1999. You will need to contact Mercury.

A:
No. They are the same.


Q:

A:
Not every seal. It contains water pump base seals, prop shaft oil seal, and shift shaft seal. Then it will contain O-rings, washers, and such.

Thunderbolt 200 20h what seal kit do I need?
A:
We will need the engine serial number in order to confirm.

It has seals for all of the lower unit.

We do not have a kit for that model motor.
