Re: [Amel Yacht Owners] march pump
Mark & Debbie Mueller
Hi Eric, I was curious and looked at the March info. I believe the 'AC' designation refers to an open style motor that should not be exposed to the possibility of water getting on the motor. The 'CP' designator is an open drip proof motor that would tolerate exposure to some drippage (?) from above. They also have TEFC motors available for some direct exposure to water. However, I think all these motors except the 'LC' submersible variety are standard carbon steel motor housings with some form of a painted finish that apparently does not tolerate a salt air or humid environment i.e. they all will show surface rust at some time. Good luck with your preventative maintenance project. Mark Mueller Brass Ring A54

Re: Heat Exchanger -- Volvo MD22 - Perkins Prima M50
Herbert Lackner
Hi Craig, if you do not have a sleeve installed then the tube goes through the baffle plate with some space (~1-2 mm) left between the plate and the tube. that means that not all the cooling liquid will run through the heat exchanger, some will circulate just through the space between the tube and the plate. right? Has anyone installed the sleeve? I was not installed on mine, but it seems to me that it should be installed... I have a sleeve in my spare parts, just do not know if I make anything better or worse if I install it according to the manual thx, herbert

Re: Heat Exchanger -- Volvo MD22 - Perkins Prima M50
Hi Herb,
This is probably the answer; from the Parts 4 Engines website: " Heat exchanger rubber tube stack seal for Perkins Prima M50, fits between the tube stack and the outer casting. Please note Perkins produced two different diameter tube stacks for use with this engine range. This seal is compatible with the 54mm ∅ tube stack." On my 1992 engine I don't have that. Cheers, Craig Briggs, SN68 Sangaris, Ft Pierce, Fl ---In amelyachtowners@..., <herbert@...> wrote : one of the end caps of the heat exchanger failed, so I had to replace it. I took the chance to examine and clean the complete system. I had all spare parts and the engine-repair-manual, so no problem. but then I found the following in the workshop repair manual (page 110): ... If a rubber sleeve is used, lubricate it with a little soap solution. Place the sleeve end of the assembly in the housing and carefully insert the sleeve in the hole in the baffle plate Carefully press the pipe ends of the housing until the journal in the housing is correctly positioned inside the end cover. Do not pull the pipe cluster backwards during installation, as this pulls the sleeve out of the baffle plate. Check through the filler opening that the sleeve is positioned correctly in the baffle plate (B).... But on the inlet of my heat exchanger there was no sleeve installed (I assume that the sleeve will be installed on the baffle plate to make sure that all the cooling liquid gets pumped through the inlet and there is no other way outside the inlet, makeing cooling efficieny better). I have a sleeve as a spare part, but do not know if it shall be installed or not. Does anyone know if the rubber sleeve has to be installed at the baffle plate? I am not sure how to understand the wording in the repair manual: * if a rubber sleeve is used... does that mean that the installation of the sleeve is optional - or does it mean that it might be another material, not rubber? without installing the sleeve I would have the same heat exchanger configuration as before. But that might be wrong, with less cooling efficieny... thx, herbert KALI MERA, SN120, Shelter Bay D11

Re: [Amel Yacht Owners] march pump
Eric, Yes, I do not like the AC because it will rust when exposed to saltwater. I find it interesting that the AC model was used and specified by Cruisaire.

Re: [Amel Yacht Owners] march pump
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.

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,
CW Bill Rouse

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.
