Complete Kit
by Lewis from Fair Haven, Vermont on February 10, 2017
This seal kit contains every part you need to reseal your lower unit. It is very easy and a good idea to account for each new part against the old parts you're removing. That way you know you haven't overlooked anything. I Boats price for this OEM parts kit is about half of a dealers price if they happen to have one.

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.

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.


Q:
Will it fit force 50hp?
A:
As long as it is in the year range of 1984-1994 then yes.


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


Q:
What seal kit will fit a sea king model?
A:
We do not have original information on that motor to offer a seal kit.


Q:
What portions of the lower unit does this kit cover i.e. shift shaft, drive shaft, prop seal?...need at least shift shaft and drive shaft seals?
A:
It has seals for all of the lower unit.


Q:
What seal kit would fit on a Chrysler 120 1209hf model?
A:
We do not have a kit for that model motor.


Q:
Where can i find the boot kind seal ?
A:
We will need to know motor application. The seal kits are cross referenced by OEM number so you get the same kit as what manufacturer offers.
