Engine Cooling Water Pump

I will be happy to, however while I have built the interiors to other boats, I have not yet gotten into my own Laser. I am trying to good quality light-weight composite paneling to work with and as soon as I do, I will start working on my own boat and post progress, procedure, methods, photos etc. I expect to be back in China and Hong Kong next month and will focus on sourcing materials. These materials are available in North America from such suppliers as Jamestown Marine, etc., but they area really expensive. This stuff is mass produced and is not actually expensive at all from the manufacturer. I just have not been able to find a retailer or wholesaler outside of the marine industry from which to buy it. As soon as it comes from a "Yacht Shop" the price goes up 10 times.

Curious, I have this wire in the larger post for the past four years. This year, my alarm went off, a high pitch, soft alarm. I always assumed my alarms never functioned before. I checked the engine temp with a hand held infrared thermometer, the engine was at 55 degrees celcius. I disconnectes the wire and alarm went off. If I put it in the smaller post and alarm stays off. I also checked oil and there is no water leaking thru the membrane. Just to be sure I checked the entire cooling system from water strainer to thermostat nothing to indicate water not flowing thru.Any thoughts? Faualty sensor? Or do I just have my wires crossed?
