Bill,

The march pump starting with AC is an open body pump and is not intended for wet environments according to the manufacturer.  I bought the AC-MD-5

and It rusted in a dry locker..

I called March today . They said I should have used the Lc-md-5 it is water cooled and submersible.

I took a look at it --looks like a better choice. same hookup just water cooled.

Fair Winds,

Eric,

I am not sure what you are referring to. Are you referring to the AC saltwater pump motor? If so, the March Magnetic Drive pump motor is isolated from the saltwater with a magnet. Thus, there is virtually no heat transfer from pump to motor.

Hi Bill,

I was wondering why the WC (water cooled) units are not recommended? i Think it was an AC-md05 

I did not like the look of the open frame AC air cooled  ( I bought one and just sitting around in a dry locker ir became cooled)  units.

Eric,

 

Eric,

 

It's a long answer, and we all have learned more since my last response. If you want the short answer, it is yes, but....

 

Long Answer:

The basic rule of thumb is 1 gallon per minute (GPM) is required for every 4,000 Btu’s of capacity. So, 9,000 * 3 = 27,000/4,000= 6.75gal/min * 3.785=25.55liters/min * 60 = 1,532 liters/hour OR, 6,75GPM * 60 = 405GPH. The March AC5-C-MD is rated at 1000 hal/hr (GPH), which is more than twice what it should be rated at. However, as you know, when all 3 ACs are running, the salon gets its required saltwater from the output of the aft AC, which has been heated because of heat transfer.. And the fore AC gets its required saltwater from the output of the aft AC and the salon AC, which has been heated because of heat transfer. I really do not know how to take all of that "pre-heated" water into account.

 

All of that said, the Calpeda pump is rated at 4.8 sq meters an hour or 1268GPH. So the  March AC5-C-MD  pumps about 25% less water than the Calpeda, but substantially more than the rule of thumb requirement from above of 405GPH. Coastal Climate Control recommends the March TE 5.5C-MD-AC, which is rated at 1500 GPH, and 50/60hz.. Mark on CREAM PUFF installed this pump and is satisfied with its performance. I think the safe thing to do is use The March TE 5.5C-MD-AC

 

I hope this helps you and others with this decision.                          

 

Best,

Hi Bill,

Do you still recommend this pump?

And, if you want a real deal on a 230 volt March pump, check this out:

I have one of these as a spare. I t hink it also might work for the Dessalator 160 liter low pressure pump.

Hi Chuck and Dan,

   I chose the Jackline policy from IMIS, finalizing the coverage right now...actually waiting for the bill.   My premium is $4100 USD, probably lower than yours because my boat is older.   Chuck is your boat UK registered?   TopSail told me their underwriters would not cover a US boat in the Caribbean.

My current insurer (TopSail UK) informed me, shortly after their invitation to renew by the way,  that they will not be able to renew my policy due to changes in the underwriters requirements.  

I followed the advice on the forum checking with a few other providers, including Y-Yacht and Pantaenius US.  Both reported that they could not provide coverage.  That left me a bit unnerved...I have been with the same company for years without issue, have no claims, keep the insured amount reasonable, and have not changed the use or location of the vessel. 

Y-yacht reported that they were not allowed to provide coverage to a US vessel due to licensing.  It was not clear if that is due to the homeport location or flag)

I pressed Pantaenius US  for a reason and their response it that it is the vessel location in the Caribbean.  Their exact response is that no coverage is provided:  "South of 30.5 degrees north latitude in the Atlantic Ocean, inland waters, Caribbean Sea, Gulf of Mexico, and the Panama Canal, between July 15th and November 1st,"

That seems to be an awfully large area with zero yacht insurance?  I asked about the southern limit, IE is Grenada OK...nope there is no southern limit.  

Can this be correct?
