My photos here barely show it, but I got an off the shelf port, (Beckson I believe), that has a top hinged, clear opening, and though it has no gasket
, it repels rain water
100%. (This is not meant to be a hull
or cabinside port at all).
It has an inward turning 2" spigot, that like the frame and lid, is a round cornered rectangle. It comes with no covering over the spigot, just a big opening.
The port's 2" spigot is about 1.5 " longer and 1.5" wider than a standard Yanmar
control panel. PERFECT!
I next got a piece of 1/4" opaque white plexiglass from a plastics shop. Then I scribed the port's spigot onto the plexiglass & cut it out.
Next I cut the square opening for the control panel, drilled the mounting screw holes for it slightly small, and tapped #10 threads into the holes.
Before mounting the panel, I glued this plexiglass back panel to the ports
(For this, one uses a syringe with square tipped needle and Methalyne Chloride to "solvent weld it", like with PVC pipe). This kit comes from the same plastics shop, btw...
Next I caulked the engine's panel into the form fitted square hole that is now recessed 2" back... in the back of the opening port.
This is followed by mounting the entire opening port into a hole cut into the cockpit's footwell.
The entire project
is less than one day...
By mounting our panel out of the Sun's UVs, and out of the rain as well, it is still pristine after 17 years! Opening it to crank or kill the engine, just takes an extra second, and there is no way to kick it and break the key off.
I recommend it highly.
