Center cockpit designed sailboats with auxiliary propulsion engines amidships tend to share a common design constraint. That is, how to lead mechanical bits aft without interfering with the aft cabin living spaces. Example bits are the engine exhaust and rudder steering.

Here I have chosen to run the engine exhaust under the floor. The cramped spaces coupled with the inflexibility of rubber exhaust hose meant that I had to put in a few elbow joints. A few more than I would prefer as the more joints, the greater the chance of leakage. But, it is what it is.

With the hose fitted I can now frame in the remaining cabinetry and floor pedestals for the aft-head.
