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.

Exactly what the Dr. ordered!
by Clint from Lakeside, California on April 04, 2015
Had a leaky drive shaft seal and opted to fix it myself. Had no problem locating the right part, and it wasn't too difficult to install and save some bucks!

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:
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:
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:
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.
