Can anyone tell me any information regarding the shaft taper of these vessels

The shaft is 1 1/16 or 1 1/4 "..the prop is three blade and the engines are 165 hp Ford Lehmans

I have two new props that I need to have turned so as to avoid three or four days on the slip

Take the 3 or 4 days on the slip. All prop tapers and keyways are machined individually and a variation of 1/4 degree or less could see you buying another prop or the added expense of remachining & fitting spacers etc. Also, make sure after machining that the prop is lapped onto the shaft properly and check for key binding (ie, the prop bottoming out on the key and not the taper). To check for this, fit the prop without the key installed and scribe a mark on the shaft at the forard edge of the prop boss. Remove the prop and refit with the key installed and check that the forard edge of the boss still lines up with the scribe mark. The prop does not need to be cranked up tight for this check, I would hand tighten the nut and then give about 60 degree turn with a wrench.
