If the through hull conduit was to be placed then it seems that due to hull/keel [space not available in hull center of side to side measurement] needs there would be requirement for twin screw o/b's in order to keep port/starboard thrusts equalized [two through hull opening/conduit to get o/b's either side of keel] . Sound and exhaust could be a problem [noisy and smelly/dangerous to inner boat portions]. Ease of service top ends my be easy [pull off o/b cowling for tune up etc]. Haul out for replacement may be made easy by having hatch directly above [pull entire o/b straight up and drop in new o/b]. Prop and gear areas would probably stay in water and need to be constructed thusly [anti corrosion materials and good seals].

Dick and Jane may like outboard power!!
