The best way is to remove the old and take it to a prop shop for replication. Boat builders have a way of changing components during a run and not doccumenting the change.

thnaks for your imput, I worked at a prop shop for a few years and understand what you are saying but our boat is in SC and we are in NY we wanted to have the replacement shaft ready to install, therefore having a short haul for the boat and not having to be out of the water for any lenght of time.

Your best bet is to contact a shaft shop in S.C. and have them on standby. They can measure the shaft diameter and interior coupling while the boat is in the water. They can make sure to have the shaft stock in hand and they might even cut the coupling diameter and coupling keyway in advance. Morgan OI''s varied quite wildly during production so that there is no really good way to accurately determine the proper shaft length and hub taper without pulling the old shaft. This is especially true since you would expect a 28 year old boat to have been repowered and re-proped by now.

A good shaft shop can cut the taper and key way in a couple hours and so you should be able to get by with a quick haulout if you find a cooperative shaft shop. One minor point, depending on the keel config (I believe that there were three available on this model) on your boat, you may not be able to pull the shaft without removing the rudder.
