Hey guys, I'm a former Chrysler now Jonny owner 1971 50hp Hydro-electric shift. We had a little problem last night with the bottom of the lake... Anyway, prop hit bottom at a relativly slow speed stopped turning no noise to speak of no loud bangs or anything. Engine reved as high as throttle control was. Brought the idle back down boat idled fine gave it a little gas no problem, Boat would not move... No Forward or Reverse. Few minutes later overheat alarm came on, shut it down quick rowed back home. <br />Any Ideas what might be wrong before I start taking it apart.<br />Thanks!
