  • 93-yami C40PLRR lower unit

    Hi gang...Just picked up a 93-Yami C40-PLRR..came off a beer barge on a freshwater lake....this "supposedly running when it came off the boat" motor was locked up...wouldnt pull start,shift or move the prop a bit..was pretty sure they seized the lower....couple hundred bucks later im tearin the lower unit off....motor spins by hand..compressions within 3 psi on both cyls....and it has electric start/trim..ALL the cables. harness teleflex and side mount WITH a key..I was hopin MASTER YODAHA Boscoe or some other parts guru could say u can swap this lower for yours if the carrier housing wont budge or cracks....(soaked in vinegar for 24 hrs...alota oxidation just melted away..been in a tranny fluid an diesel dunk for 3 days).Im bettin the carrier will come out....BUT,,Just in case..LOL ....any input would be more than welcome...Thanks...Mike

      I just noticed your lower unit has the big nut and claw washer like my brothers C60 has.
      here is a thread I did on pulling that one apart also.
      might give you info on how I had to pull that carrier
