I'm in the middle of playing around with a 1959 3hp Evinrude. I took the lower unit apart to check out the impeller. All around the impeller housing and the unit itself was a bunch of crud, looks like old gear oil type stuff, greasy/oily. And removing the water pump plate it was all the same. A bunch of oily/greasy build up. Is this normal or should I also replace the oil seal while it is apart.? Is that seal difficult to remove and replace? I didn't think of taking photos at the time.
Thanks for any info.
