Re: Help with a MERCURY 110, 9.8hp

[David Stanton]

Your 9.8 Merc is a 1973 model and the gas/oil mix is 50 to 1. The first thing to do is remove the prop and see if there is fish line caught in the prop-shaft seal. Sometimes you get lucky and fix the leak by removing the fish line. I haven’t put a sealkit in your model so someone else here can tell you what tools you need.
