I tried a microfiber with polish. No effect. Ended up using a light rubbing compound with a DA. By hand didn’t work with compound. After that, I polished it and waxed it. I just got back from the hardware store with $40 of SS screws, nuts, washers and silicone sealer. I wish I was in Seattle so Helmsman could do this repair.
Now that it appears no one else has this problem, I’ll contact him.
As you can see in the picture below, I replaced the GX 50 with a GX 70 and mounted it behind the helm seat. Very easy installation. It makes watch power and managing power very easy. No need to lay on the deck to see the display.
No gen set. I’m pre wired and plumbed for one. I’m experimenting. Scott provided this interlocked switch over from shore to inverter.
That's a great idea to mount that outside of the electrical panel. Plus it kind of looks cool!
Yes, it makes sense with no generator. Or even if you have a generator, it’s important to see what’s going on. There is just so much useful information you can see on the GX70 display. Power management is important too. With only 30 amp service, don’t try to run your microwave if the air conditioners are running. You’ll be climbing into the lazzarette to reset the circuit breaker. But, the shore power wattage is not displayed. You need an additional power monitor module, which should be on our boats. I’m going to get one one I’m home. It’s only a few hundred $$$.
Do you run an electric water heater while at anchor with your set up or do you have hydronic heat/hot water?
I’ve found that while traveling, the engine heats the water sufficiently that it’s still hot in the morning. I’ve not anchored in the same place more than one day, so I don’t know if I could hear the water off the batteries. Running the engine for a half hour would likely do the trick. .3 gallons an hour at idle isn’t bad. Would charge the batteries and heat the water for the day.
All the loads on the AC bus that are connected to the Multiplus inverter do automatically switch over. My air conditioner is not directly on that bus. I have to intentionally run it off my house batteries, anltenator and solar batteries.
Correction to your question about running the hot water heater on anchor. The water heater is AC. It is not powered from the inverter bus. Therefore you must be on shore power or have run your engine enough to provide some very hot water.
No, I can only add the air conditioner to the inverter additionally. Please look back on my posts and you will see the interlocked switch for changing the pilothouse air conditioner from shore power to inverter power.
