Noticing that my VHF wasn’t sending or receiving its usual strong signal, I found some corrosion between the coupling wires and the mount. How can I prevent this? R.A., via e-mail
Salt water has likely worked its way into the space. Take the coupling apart, and brighten any affected wires (they’ll be green) with sandpaper or emery cloth. Remove any corrosion in the coupling as well. If necessary, cut back the wire to expose bright material. Use liquid electrical tape on the new connection to prevent further corrosion. With everything back together, seal any gaps with a bead of clear silicone. Check once a year.

How long will a two-part epoxy topside paint job usually last? C.F., via e-mail
That depends on several factors. The first and probably most important is your boat’s location. The sunnier the locale, the more your boat’s exterior will be exposed to harmful rays. Add to that daily and seasonal differences in humidity and ambient temperature, rainfall, and the saltwater environment, and the life expectancy of a bright topsides paint job can be severely diminished. And remember that light colors reflect some of the sun’s harmful rays and remain glossy longer.

Another key factor is how well you maintain the finish with regular washdowns. Scrapes, dings, gouges, and any other surface damage should be repaired as soon as possible to prevent moisture infiltration.

Properly maintained and taken care of, a two-part epoxy paint job will last from two to six years. For more detailed information, contact any of the major paint companies such as Interlux (908) 686-1300, www.yachtpaint.com, and Pettit (800) 221-4466, www.kop-coat.com.

How can I troubleshoot my pressurized water system? T.H., via e-mail
First top off your water tank. Next open a tap. If the pump does not come on, check the breaker or fuse and all electrical connections. If you have a separate pump switch, check it for faulty connections or corrosion. If the pump comes on but no water comes out, examine the plumbing for kinks and the tank vent for an obstruction. If the pump comes on and stays on, check for leaks.

As a general rule, keep the tank full, as this makes it easier for the pump to work.
