Rebuilding Tortuga - Removing the Chrysler Crown Engine  The
engine in the boat is a 110 h.p. Chrysler Crown flathead 6
gasoline engine with a mechanical gear.  Checking through the
documentation that came with the boat, the engine appears to be
a 1950 vintage M47s that was installed in the boat in February
1952 about 2 weeks before I was born.  When I first looked the
boat over, it was clear that all was not right with the engine
since I could not turn the engine at all by reefing on the
flywheel.  Also, I couldn't turn the prop at all with the gear
in neutral.  when I visited the boat for the second time, I was
able to slightly budge the prop, but again failed to turn the
engine at all despite applying a couple of undered foot pounds
of torque to the flywheel.  The previous owner said the engine
was running in 2004, but the three year layup obviously wasn't
good for it.  Because of the condition of the engine we decided
to repower the boat with a smaller diesel.  Repowering will get
rid of the gas on the bo
