Practical Sailor Tests Spray-On Protection for Electronics and Electrical Systems

Seawater and electricity love each other with a fatal attraction, and when they break barriers to get to each other, we suffer from the destruction left in their wakes. Enter aerosol corrosion inhibitors. If you spray sensitive electrical circuitry-including printed circuit boards-with the aerosol rust inhibitors we tested, theyll prevent corrosion from interrupting circuits and water from creating circuits where they arent wanted. Our test lineup included Boeshield T-9, Corrosion Block, CorrosionPro Lube, CorrosionX, CRC Heavy Duty Corrosion Inhibitor, CRC QD, LPS 1, Strikehold, TC-11, WD-40. The TC-11 was our top pick.

Bilge Setup Keeps Electrical Bits High and Dry

In your continuing review of bilge pumps and automatic switches, you may want to include a somewhat atypical approach that has worked very nicely on my 1964 Rhodes Reliant. It is based on the simple premise that any electrical components (pumps, wires, connectors) in the bilge are at risk of corrosion and galvanic action. Bilge electrical components can be unreliable and may cause serious damage. Hence, there should be no electrical components below the floorboards. Here’s how I did it.

Multi-stage Battery Regulators

I am building an electrical system that will hopefully support wife and two teenage daughters. With this objective, I am planning approximately 1,000-amp hour battery bank. I see lots of hype about the external three-stage voltage regulators. Do they really provide more amp hours during the limited engine running time? If so, I have not found any definitive side-by-side comparisons that convince me that three-stage regulation is more efficient than a single-stage constant voltage regulator.

Strippers and Crimpers

One crimp or two? In our test and survey, we again find that the well-made multi-purpose tool will suffice for most wiring jobs. If you have more serious work to do, try Klein's #1005 crimper and Ancor's 702030 automatic stripper.

Caring For Your Marine Diesel Engine

Expecting calms for most of the passage, we set out in a flat calm with 70 gallons of fuel. Six hours later, around mid-day, the engine wailed, screeched, clanged, and died. Hardly a ripple stirred the Gulf of Panama.
