I have a J15RSDR motor. I bought a lower unit for it. I am converting it to a long shaft from short shaft. I have all that I need, except the copper tube in my midsection currently is not long enough. I call a mechanic and ask how to remove the current copper tube and replace with longer one as needed. I was told "just pull it out, it will slip right out, no problem" WRONG, IT WILL NOT. in the mean time I have completely destroyed my copper tube that is in the motor now, so I am fully committed, I have to get it out. Somebody please help me....i need it...."aw just pull on it, it will slip right out"ugh.
