Marine Air Conditioning System Maintenance
November 5, 2010 By
Greetings All, Let's start with the basics... Seawater flow thru your A/C system is primary... Without water flow....You have NO cooling ! Service people on the docks (at least the better ones) can walk down the dock during the summer and tell which boats they are likely to be getting a call from next just by the flow of water (or lack of) going overboard on each boat....Lack of seawater flow can cause other problems besides loss of cooling... Lack of seawater flow causes high system … [Read more...]

September 2, 2009 By
Below is another copy of a post I made in the Meridian Owners Forum...If you want the full jest...http://www.meridianyachtowners.com/forum/forums/thread-view.asp?tid=1957&posts=15#M18424 Hi Mark...Don't know if you are still watching this thread, or if you have seen my thread over in the "Introduce Yourself" forum but here's my take...

Copy of recent e-mail to Marine AC.com... Hi Steve, love your web site - lots of great info. !

Pumps & High Pressure…With Manual Controls & Hi Pressure Switch
August 10, 2009 By
Recently I was on a boating message board and came across a discussion about pumps and some troubles folks had experienced. The original poster had a March magnetic drive pump that would not pump water, and after the usual back flush & priming sugguestions he could still not get it to pump water…Just before I read the thread he had found that either something had gotten past the strainer (or he didn't have one) and had lodged between the impeller magnet and the pump housing … [Read more...]
Marine A/C Pumps and Pump Relays
August 7, 2009 By
We have touched on seawater cooling and lack of...Now what about if you have a intermittent problem, or the pump won't start at all ? In boats with multiple systems running on one seawater pump there is most likely a Pump Relay to receive a signal from each system to tell the pump it needs to run...That is unless it has been bypassed and the pump runs 24/7 from the breaker ( I see this done fairly often) Lets start with the breaker in the main panel...Most are labeled A/C pump or … [Read more...]

Here's to hoping your New Year is Prosperous...and Regardless of the present status of the economy...I'm sure that most all of us are feeling the same pinch !
