I have 1994 Force 120Hp with a badly leaking prop seal. I looked at it today and blue gear oil was leaking pretty bad from the seal. i can hear some grit when I turn the prop.<br /><br />I have the shop manual but it looks pretty involved. I'm mechanicly inclined but I just wanted to hear from some experience folks weather its worth it to do it myself or pay to have it done. Thanks!
