I am in the process of developing a lifeboat design, primarily intended for
Coast Guard Auxiliary applications.  My conceptual propulsion system at this
time is a Mazda 13B engine mated to an appropriate transmission (with a
hydraulic pump PTO) and water jet drive.  I am currently in need of exterior
engine dimensions, as I need to minimize the overall height of the engine
configuration (as well as optimize maintenance access), consequently the
"plugs up" configuration may be appropriate for my application.  If
possible, please refer me to a source for dimensioned exterior 13B engine
drawings.  Any thoughts you may have regarding my intended application will
be greatly appreciated.  Thank-you in advance for your assistance.

Have you heard of Rotary Power Marine?
Plugs up is bad news. You risk overheating the engine and there are oil
drain back problems. The basic engine is just as low right side up when
you consider the height of the spark plugs. Only years ago when people used
distributors was the engine lower plugs up. Nobody runs a distributor
to my knowledge.
