Im doing some winter projects on my boat and had a question about the jet. How freely should the pump shaft turn?? I disconnected the drive line from the motor and tried spinning it. It will turn with no noise, however i cant just spin it and watch it spin if i let go. I have to apply a little bit of force but not a ton......makes sense?? I would say that my 5 yo could probably turn it but not very well. Im just not sure how loose its supposed to be.
