You might consider adding a fresh water flush to your system. IE like this https://easyflowflushing.com/product/easy-flow-flushing-kit/ I'm not advocating their system but just the idea. I added something to my old 310 and found that as long as I was religious about flushing after use it seemed...
You would be correct but I have used ablative bottom paint on the brass seacocks / strainers and it wasn't the end of the world. For trim tabs / props / struts I used spay on zinc (Pettit Prop coat- good for about 6 months). If you have outdrives / aluminum I would use an aluminum safe paint...
As mentioned above spectrum at https://spectrumcolor.com/. Call them regarding a repair kit. They also have good videos on youtube on how to. Even if the color is slightly off you will not see it after a season. Best of luck
Yes, different materials need different paints. You can not put your standard paint on an outdrive or within an inch or so of the drive. I used petite zinc spray on the metal (except outdrive) rudder / shafts / trim tabs but the tabs where steel.
I think either way for your situation you will be fine. If they have lasted 4 years and lasted good, I would use the same. A new charger that takes into account the battery type and charging cycle for each is also a good idea. My only caveat is that I would swap one bank now and the other at the...
In total how many batteries do you have? How long have they lived on the boat?
I think you would be fine with deep cycle batteries for your house. Normally dual purpose / starting batteries are for the engines batteries (they can support high amperage for cranking for a short bit). If you have...
Wow, I guess one of them was misfiring, are you getting 60 hertz? Regarding the wiring my best guess is something is loose for it to stop working remotely.
Is plugs = spark plugs or capacitors?
110 under load or no load? The voltage will drop a little with load, that is normal. Mine without load is 120-124 volts. Under heavy load / the AC on it runs about 116-117 volts. Something similar when I am on shore power. So as long as things are running...
3 pick ups with one pumping unit, one for the center bilge and 1 for both compartments around the rudders. It does work quite well but is slow. I bought it for convenience. I looked at pumps and figured it would be at least 100-150 for parts plus the timing circuit but at least a few hours (and...

I purchased it last year, have it about 6 months. It does work but pumps out slowly. If you allow it to run a few minutes a couple of times daily it does do the trick. Best of luck
