Johnson 35hp, model# 35el76s, jumps in and out of forward at speeds above idle. From what I have read in past posts, sounds like the clutch dog and gears needs replacing. My question is how hard of a job is this for the average do it yourself mechanic? I have had lower units off for water pump replacement before, but never had one apart. Any special tools required, etc.? Also, what kind of $$$ am I looking at here? Thanks, Nick
