You do not need to remove both screws. Only the bottom one. It’s just that it needs to be removed completely. It sounds like you have already done that. Not sure why it is still stuck. Could be rusted drive shaft splines. It.could also be the water tube grommets stuck on the tube. I have had those get stuck pretty good to the point of pulling one of the grommets out of its seat and having it still stuck to the water tube.

well I took out the lower squeeze bolt on the shift rod ” link” just above the water pump and that did it… it (gear case) came sliding down no problem

Amazing because that squeeze bolt was… .almost out and yet the shift rod would not let go of it

everything else looks ok except the drive shaft rubber grommet above the pump … needs a new one and…. a new impeller

thanks

You’re welcome. I’m glad to hear you got it to drop down. That pinch bolt passes thru a notch in the shift rod so it’s retained even if the bolt becomes loose enough that friction doesn’t hold it. Be extra careful when you replace the lower unit that the notch in the shift rod is lined up as perfectly as possible with the pinch bolt hole. If it is misaligned, the threads on the pinch bolt can get damaged when the bolt is replaced. That will in turn damage the threads in the clamp and ruin it. Not difficult, just something to pay attention to so things don’t get damaged accidentally. 😉

Chris P’s advice here is very sound as well. While important to replace the O ring amd grease the drive shaft splines on all motors that have them, it is extra important with these motors since they sit so close to the water.
