Upper Lower Crankshaft / Crankcase seals
by Glenn from Havre De Grace, Maryland on June 01, 2016
I purchased two of these $2 seals as well as two tab locks that we $0.99 each but because the parts came from different warehouses I paid two shipping charges. In essence less than $6 worth of parts cost me about $31 to reach my house. The tab locks are no larger than a nickel but they packaged these two steel in a box that was 4X4X6. A waste of a box, not economical for me, even with dealer mark up I could have paid full retail value, had them the same day and saved $$$$. Fool me once, shame on me and there won't be a second chance. Sales should have told me there were two shipping charges.

solid products and fast shipping to mn
by Bryan from Big Lake, Minnesota on April 17, 2011
Guessing if your ordering this you already pulled the gimble bearing. To get this seal out the gimble bearing needs to come out, and chances are your not getting it out without ruining it. I would suggest if your not already planning on it to replace the gimble bearing at the same time. I used a slide hammer to pull this and the gimble bearing out. Seal comes out with ease, bearing was a little more banging with the slide hammer. Project started by going after the drive cable, but ended up replacing the gimble bearing and seal at the same time since the bearing was not 100% smooth when turned by my fingers. Would have only been a matter of time before I needed to pull it all apart again. Best part is how fast iboats gets my orders to me. Ordered on a Wednesday night, and parts delivered Friday afternoon with the standard shipping.

Q:
Need propeller shaft seal MERCURY pn. 26-98283 1983 25HP?
A:
Unfortunately we do not have a cross reference with that, you will need to contact Mercury.


Q:
Where is the 2nd seal behind this seal backwards? Do I order 2 of these?
A:
Typically these require two seals, but we will need your engine information to verify.


Q:
Will that seal work on my 1989 500-50hp Canada built, sn7079786?
A:
The 500 model did not have a production year in 1989. In that year as well there were no models listed with that serial number. If you can double check info and give us a call we can assist you further.


Q:
Sierra oil seal 18-2052, will that work with my 50 HP Mercury 1980/1981?
A:
Looking at the serial number ranges for those years those would work, 5531630-9248006 is the serial ranges it fits within.


Q:
I have a 2000 XR6. I need the seal for the two power trim cylinders (the starboard one is leaking) and the tool to remove the cap and reinstall it. Can you guide me to the correct part?
A:
Unfortunately this seal is not to the trim system. It is just to the lower unit. You will need to contact Mercury on the seal for the trim cylinders.


Q:
How do you recommend to install this seal?
A:
We are not technicians, but you can use a repair manual and if you need some installation help you can contact a dealer. You will need some type of seal puller and then some way of pushing in the replacement seal. It might require taking off some components off the outdrive. Repair manual will have a step by step guide.


Q:
Will this fit 89 sunbird with omc cobra sterndrive?
A:
This prop shaft seal is made for Mercury/Mercruiser, not OMC. You will need to give us your model number to your OMC engine and we can see what we have. Call us at 1-800-914-1123.
