| The 3/4" flush thru-hull for head sink drain installed, but where is the 1 1/2" thru-hull for black water discharge? |
Due to poor communication between Anne inside the boat
and myself outside the boat, we over tightened the 1 ½” black water discharge
thru-hull. Yes you can crack a marelon thru-hull fitting. Fortunately we both heard a pop and removed
the fitting to investigate.
 |
| Crack along inside face of outer flange. Crack does not extend to opposite face of fitting. |
The crack occurred on the inside face of the outer
flange. It does not extend all the way
through the fitting, but we conservatively chose to purchase a new
fitting. No sense taking chances with a
mission critical piece of hardware. We
have ordered a new thru-hull fitting. Ironically this occurred after successfully installing four other fittings...
 |
| New 3/4" seacock for head sink drain is the only fitting remounted in it's original location. Note filled holes from original fittings on left in image. |

| External view of new 1 1/2" engine raw water intake located on starboard. |
 |
| Seacock for engine raw water in-take is now located below quarter berth deck. |
 |
| The new 3/4" house raw water intake is located in the wet locker portside, forward of the nav station. |
