For full disclosure, Iím not selling anything nor am I getting any commission or affiliate link or any such thing. I bought all my products because I thought they were the best for the money. The AmpereTime batteries are excellent drop in replacements with sophisticated battery management systems, quality cells and construction. Completely sealed, making them an excellent choice for marine applications. They donít have low temperature charging protection so not appropriate for boaters needing to charge below freezing temperatures. Nothing Iíll ever experience in my boat.

Here's a PDF that provides an overview of what I did to upgrade my MKII with LiFePo4 house battery and solar charging. We like to anchor in remote-ish parts of Biscayne Bay for weekends and long-weekends with constant refrigeration and fans. So far the system works well.

Would love feedback, opinions and questions. I'm not in any way an expert but I've been researching it all quite intensely for a while now.

Robert, do you recall the length of the hose? I have 30 feet.

I don't but it only had to run about half the length of the boat so I probably got 20ft and had some left over.  I used the leftover to create a chaff guard on my most active (windward) dock lines.

I replaced my electric bilge pump hose and it wasn't very difficult. There aren't any places that you can't reach to guide it. Lots of tie-wraps to cut and replace.

Here's another example of securing an inner stay:

... So the goopy material was coolant that was basically leaking and than heating up and turning into basically a Vaseline type material....

Looks like a confirmation of it being: Blue Devil Gasket Sealant, as mentioned above.

I too have an all-chain setup but only 150ft because I'm in Biscayne Bay (Miami) and this boat will likely only ever get me to the Bahamas at some point. My MKII has the vertical Maxwell and only goes up as well.  I thought this would bother me but the locker/castling issue and the fact that anchors have to be secured/unsecured and snubbed, not just taken up or down, has me convinced that neither the switch or a remote would be of value, at least to me. The only guy I know that has a chain counter didn't fix it when it broke.  :D


I had initially considered this orientation as it would GREATLY simplify the installation.  However, I felt that it would not give linear results to rudder's position.  Thus, I am in the process of locating a place to adhere a mounting block to the underside of the cockpit in line with the rudder post to provide a more parallel installation of the sensor.  I figure if I'm going to bother to go this far, I want it to be installed as close to the way Raymarine set up the hardware/software interface to be.

Alex, you should reconsider this option. It is absolutely equivalent to what Raymarine advises. The geometry is the same. All that matters is the the arms are parallel and the connector is at 90 degrees to both arms. After I did mine, I went looking for confirmation of this and found in on Mainsail's website. I was actually pretty stoked to see he even used the same plastic for mounting to the radial wheel.

My instructions, particularly the positioning of the sensor is specific to the MKII. But one takeaway I didn't emphasize but should have is that the Raymarine instructions only show one way to align the sensor axis with the rudder axis (in a U), but there is also the possibility to align it as I have Like this:


Thanks, I will definitely report back on if, and how well, it improves the auto-pilot performance.

I have the Raymarine Evolution EV-100 Wheel Autopilot Pack w/ P70s Control Head purchased 12/12/2020.

Finally tackled this project on my MKII and I think this document might be helpful to motivate others to do the same. :clap

See link to PDF for a mostly pictures description of how I did it. I tried to upload PDF but it was a little larger than the 1024KB limit per file...  :shock:

JunoóMaybe? But the ďneed to run it 90 minutes TWICE DAILYĒ  sounds suspicious for a large alternator feeding a lithium bank.

Agreed, maybe large second alternator feeding crappy old batteries?  :shock:

The Mooring's guy undoubtedly knows what he's talking about for his own boats. This is probably a dual-alternator design with a huge second alternator to charge a lithium system, which you wouldn't want killing your horsepower when you need to steam, so it has a relay that only allows it to run in neutral. The biggest pet peave I had when chartering was the crappy house banks that couldn't keep the fridges running even 18 hours... A constant headache.

I've been using, which is freeware. It works ok, price is right. Visio is better if you want to part with the money.

Iíd hoped for a meaningful response to my question from the two gentlemen, but after 10 days guess Iím not getting one.

Another forum member beat me to the answer, so I didn't feel it necessary to "me too" it.

Thanks for all your research with the "engineering types" on YT. That's super helpful to know we can trust the advice, given the sources were "engineering types" on YT.

Are we done with the veiled insults now or we can act like men?
