So, my buddy has a Woolly AK II with a baykit extension on his yamaha 150. We took the lower unit off and the 5" extension stayed in the powerhead. We have tried some pretty ingenious ways to remove that thing, but it won't budge. Does anyone have any ideas or know of a tool that will expand like a boat plug that we could stick up in the shaft, then grip and pull it out? Tried it with the boat plug, but it didn't grip it well enough. Our next step is to remove the powerhead and we rather not go that route. ?????????
