	I am building a 34' sailboat.  It has been suggested that I use
a rabbit diesel engine.  The idea is to use a reduction gear.  Further,
the suggestion was made to use some copper tubing laid along the keel to
cool the engine.  The cooling system would be a closed-loop set-up, using
fresh-water only.  It appears to be a great idea on the surface.  No ex-
pensive saltwater conversion equipment would be required.  The engin is
relatively light in weight for the power it produces.  

	There are, however, a couple of questions.  What kind of a reduc-
tion gear is required?  What kind of propellor is desirable?  How many
feet of what diameter copper tubing is needed to do the job?  That already
is more than a couple.  WE could probably come up with a few more.

	Do any of you readers have solutions to suggest, or can you suggest
ways to answer these questions?  Please reply by mail, or if you think 
of things we believe are of general interest, we get a lively discussion
going.  Thank you ahead of time.  


				Hopefully yours,
