1975 Johnson 70hp SeaHorse (Model 70ESL75B)clicks (grinds)loudly when going into gear (forward most notible) Particularly as it revs up as you push the hammer forward. Seems to rev too fast before it gets into gear. It jumps in and out until it gets moving. Works perfect other than this.<br />How do you adjust this properly? I have a Manual on the way, but someone with experience would be helpful!!
