Getting the coupling back on the shaft... in the water
I decided to pull our prop & shaft with the boat in the water, so we could get both shaft and prop checked due to a vibration. This turned out to be a good bet, since it was two weeks turnaround to get the maxprop to/from PYI, now rebalanced and shiny as new.. (we live aboard, so two+ weeks on the hard would be somewhat disruptive)..
I've been test fitting the reassembly before it goes into the water, and I cannot get the coupling back on the shaft.
The shaft guy said that on the hard they usually attach the coupling halves and then use force to bang the shaft back in. He wasn't familiar with the proper procedure in the water.
The coupling is a walter-style split coupling. I've been trying to work it onto the shaft, but it won't go on very far.
I suspect that I need to just bend the halves further apart, I have worked them a little bit by hammering a pry bar in between them. It was on the shaft really tight and was a pain to get off to begin with.
Anyone have any advise or ideas on how to approach this?
Shaft couplings always seem to be a source of pain... I would even replace the coupling if there's a style that is easier to work with. (like maybe something that splits into two pieces?)
