My M17 has a masthead tricolor, red and green in front, white in back, one bulb. No "anchor light" as such. The tricolor is very similar to the Aquasignal series 40, although it doesn't look as if Aquasignal makes the tricolor anymore, but rather a bicolor with anchor light, which would seem to better meet your needs anyway. The light is mounted on a pedestal screwed to the masthead and the wiring runs through the mast to a through-deck (through-hull) plug next to that mast-step. The West Marine catalog link is: http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=1... ductId=17988 I imagine, with a link this long, you'll have to copy and paste it to your internet address window. My light is shot, it's so old the plastic is very clouded, and I've been thinking about alternatives to the masthead, but lately I've been thinking maybe I prefer to have all nav. lights at the top of the mast, up out of the way. ----- Original Message ----- From: "Bill Sylvester" <wmcsyl1@cox.net> To: <montgomery_boats@mailman.xmission.com> Sent: Saturday, January 10, 2004 7:55 PM Subject: New Old M-17 Endelig is coming along. I am now working on the lighting. Cabin and fore and aft running lights are now working. Did old M-17's have a masthead anchor light? There is a switch on the panel which says "Mast" and a dead end wire at the aft edge of the forward hatch but I see no evidence of an opening or wire stub going to the mast or a place for mounting on the masthead. The previous owner told me that she had knocked the anchor light off when she was stepping the mast, but could not find the fixture. I have really looked the mast over and can't find a place where it might have been attached. Can you help me, again? Thanks, Bill Sylvester M-17 #279 Endelig
