    boat lift mast corrosion

    We had to replace the mast on my small boat lift due to corrosion and mollusk overgrowth. This occurred mostly due to neglect by the previous owner. New mast has a new zinc and I will use it enough to prevent mollusk growth. My question, is some of the corrosion due to galvanic reaction . I...

    what does this wire do

    Red wire turned out to be an aftermarket spotlight which did not work at the light but did have tiny indicator lights at the directional switch on the helm that I only noticed when working on the boat in the dark with a head lamp, pulled the fuse and the indicators went out. Will dc the light...

    Air Conditioning and Solar - curious

    At first I got a chuckle from the question, but after thinking about it I began to feel it was somewhat of a dangerous question/post. As for the portable generator I urge you to just look at the restrictions/zoning requirements of installing a residential standby generator. Look at the window...

    what does this wire do

    Got some good work done today in spite of Dorian. Cleaned up all unknown wires except that red 10 ga from the stern. Seems like it is going to the helm switch panel but still not 100 %. New question is the dc 50 amp breaker at bulk head ac/dc panel . Seems to me that should be the main and...

    Re-wiring a boat?

    While I would love to rewire my old girl and start fresh I know that is a pipe dream. I do second the connection remarks as that is what i have done and am doing. No inline fuses, fuse boxes only and negative buss and new connectors have already made a huge difference for me.

    what does this wire do

    Yea I see Bubbas tracks all over this boat. Why do people just leave cut wires hanging around to confuse those down the road rather than cleaning up as you go.

    Just wondering as I sit here in Fort Pierce waiting for Dorian if the situation gets really bad and we need gas, well. I guess there is 150 gallons in the boat. If I really need it how would you go about getting some out. thanks

    what does this wire do

    finished the transom/bilge redo. New batteries, neg buss, 6 circuit pos fuse panel, 3 new battery switches, new float switch and a general good clean up. Looks and works fine. Question is a 10 gauge wire which was a direct battery connection with a large 20-30 amp inline fuse (so corroded...

    92 Marlin electrical upgrade

    Spent 4 days in Fl working on the boat. Replaced several switches and breakers at the helm panel. New Wire Marine switches and only needed very minor mod to the holes with a small file. Have more to do but need custom labels. Replaced the factory charger with Pro Nautic 12/30 3 bank...

    98 Marlin Battery Charger - Tripping Breaker

    That does not seem to be the recommended arrangement from my research. The engine batteries should not be used to power sensitive or important dc loads. Just sit in your car and turn the switch to acc position, dash lights up, radio will come on, etc... then start car all the prior go dark...

    fusing 30 amp charger

    Of course each bank is fused individually and since it has intelligent distribution and theoretically could dump all 30 amps into one battery the logic for each output to be fused at 40 amp. My question was how to avoid the inline fuses. I solved it and ordered a 3 bank mrbf blue sea fuse...

    fusing 30 amp charger

    I bought the Pronautic 30 amp charger and was wondering how most fuse the 3 outputs. Manual states 10 amps greater than charger output, so that is 40 amp fuses. Was hoping to avoid inline fuse holders, but a marine multi fuse block rated for 40 amp per circuit is tough to find. Any ideas

    92 Marlin electrical upgrade

    I seem to have been wrong about how batteries are wired. One bat to start each engine then the other 2 ind or in parallel for house. Sure could use some help figuring out how the charging is wired, both from engines and shore power. I will need a new charger, 3 new battery switches for sure.

    Coffee Maker for a boat

    bringing water safely to a near boil is the first priority. French press is easy but messy to clean up. Pour over is simple and really makes some of the best coffee you can produce, some filters and a holder and you are set. My go to emergency, simplest, and really not bad coffee is Starbucks...
