Project Log:  Thursday, February 27, 2014

As a sort of dry run for installing the red and green sidelights, I thought I'd wire up and install the stern light first, to get a sense of how much wire was required to insert into the fitting for connection, and to allow the light to be removed for maintenance/bulb replacement.  Since there was an existing bracket on the stern pulpit, and the old stern light was the same thing, installing the new one would be a good trial before I finalized the installation on the new running boards (which were now complete, untaped, and ready to install).


After determining the wire already in place in the stern pulpit was in good condition, I'd left it in place rather than replace it, and had left an ample amount dangling by the stern light bracket.  To wire the stern light, I led the end of the cable into the fixture after removing the various collars and clamping nuts, then stripped the wire ends and inserted them in the wire clamps provided within the fixture, beneath the bulb housing.  After reassembling the light base, it was easy to install it on the bracket.  I left a small wire loop beneath the light, and added some split loom for better looks.  Sometime later, I'd finalize the wire connection between the pulpit light and the new cable I'd run from the electrical panel.

The job was straightforward, but required a fair bit of fussy work with tiny screws, but all in all I liked the fixture.


Back in the head, I mocked up the two seacock arrangements, for the head intake and discharge, to get a sense of their final placement and how various configurations might affect and dictate the final height of the platform for the marine toilet.  The valves would go beneath the platform, but would remain accessible from the inboard side.

My initial thought in an attempt to save space, and keep the platform at a usable height, was to use a 90° elbow between the through hull flange and the 1-1/2" valve body, hoping this would keep the arrangement as low as possible by sort of paralleling the hull itself.  I roughed out some height marks on the adjacent bulkhead to clear the assembly.


However, the more I looked at this, I wasn't sure.  The real problem arose from allowing the valve handle room to operate.  When closed, the handle projected well above the valve body, and essentially negated the space savings afforded by the elbow.  Plus, the elbow still raised the height quite a bit.  In addition to the orientation shown above, I also turned the valve 90°, to aim forward rather than "upward", and this had some merit, but the valve handle was still a significant problem.

So I decided to try the valve in its normal, vertical position, eliminating the elbow (which, ideally, I'd prefer anyway), and using a 90° hose fitting on the valve to turn the hose.  As it happened, this worked out better:  the overall clearance height required actually ended up a bit less than with the elbow, with no additional room required for the valve handle, and an easier orientation of the valve for regular operation.

In the last photo of this series, you can see the black marks on the bulkhead:  the two upper ones were the ones from the 90° valve alignment, while the lowest one, just behind the valve, represents the minimum height of the platform with the valve in its vertical orientation.


Satisfied with this arrangement, I marked the hull around the fiberglass base plate for future alignment purposes.  Then, I tested the smaller 3/4" fitting assembly for the intake; its height was less than the big valve, and after a time I determined the most favorable location for the valve and marked its base plate location as well.


Afterwards, I drilled the holes for the through hulls themselves, as marked.

Finally, I epoxied the two base plates to the hull, keeping them aligned with the marks and with the holes in the hull.  I left these to cure so they'd be ready for the through hull/seacock installation next time.
