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:
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.
