Re: Shorten prop on Chrysler?
SHORT answer---probably not.
Depends on whether that was the one piece or two piece lower unit. If the engine has two carbs, it is the one piece lower unit and I think they were only made in long shaft.
If it was the two piece lower unit, then you need to find a short drive shaft, a short midleg and unmount the engine and remount on the short leg. MUCH MUCH easier to raise the transom 5 inches. There are some old threads (I think in boat repair and restoration) on rebuilding and raising short transoms.
For a more definite answer, go to the Chrysler Crew Chat Room tonight (thursday) at 9-11PM Eastern Standard Time.
