We added an access door on Hakuna Matata for the HX Zinc.  I was tired of having to be double jointed to get to the zinc.  Now the whole process is 5 minutes.  Find the new zinc, 9/16 wrench, open door, put rags down and remove and replace.  DONE.  Worth the few bucks for the door and time.

I put in an access hatch as one of my first projects after I purchased my boat last April.  It has made a huge difference in all the work I have performed on the engine since then:  remove and replace heat exchanger, paint rear of engine, remove exhaust flange, remove and install new exhaust riser, all new engine hoses, and all new wiring.

I found the perfect hatch at Great Lakes Skipper for about $90.  The hatch removes completely, and it is about the maximum size to cut into the panel below the shelf behind the motor: 11" X 23".  Part number is 582-1123-05.

Simple to install. Trace the cutout of the hatch frame.  Use a small hole saw to cut the radius of the corners, and your multi-tool to cut the straight sections.  Rough sand the edges of the cutout with 80 grit.  Drill pilot holes for the frame and screw in place.  The frame is gasketed, so no caulk needed for mounting.

Sorry for no pics.
