just got a 94 25hp evinrude tiller motor with thur-hub exhust,when i removed the prop there was only a carter pin ,nut,washer and spacer with key slots that fit over shaft.didnt know if there should be an oil seal in there or not? i didnt see one and the break-down picture i see on iboats show an oil seal/o-ring(2 of them) did not know if it was a thur-hub exhust picture i was looking at or not.iam only concerned because when running the motor i get alot of grey grease like build-up inside the prop....any help? its my first tiller.
