DON CASEY: There will be very little difference in the power output among reputable
brands of VHF radios. Where most installations
go wrong is in selecting a cheap antenna or
small coax. Choose the brand of radio based on
reputation for reliability, not performance. Select
their least expensive model that has the features
you want. Where you want to spend a little extra
are on the antenna and cable. The trick to good
performance is getting all of the power the radio
delivers out into the air, and that requires big
cable and a good antenna. Do your homework
here and you’ll end up with an installation that
will never leave you out of the loop. (For more
information, see “Installing A VHF Radio,” in
our new DIY section on page 70.)
I NEED TO REPLACE A CIRCUIT BREAK-ER/SWITCH. The switch toggle is broken
off and even though the breaker still seems
to work fine, the survey says replace it. The
original breaker is a 2.5-amp and all I can
find for a replacement is a 5-amp. Is it ok to
install the 5-amp in place of the 2. 5?
JOHN ADEY: That’s a great question.
You’re going to need to stick with that 2.5-amp
breaker. The size of the wire and other electrical components in that panel all take into
account that the circuit will not exceed the trip
level of that 2.5-amp breaker. Increasing the
amperage could result in excessive heat and
potentially a fire. If I were the surveyor and
came back to check on your installation, I’d
write it up again.
This is one area where you don’t want to use
the theory of “bigger is better”!
CLARITY ON LOW-SULFUR DIESEL
After owners of marine gasoline engines were
plagued with problems related to the switch
to ethanol, owners of diesels have been
understandably wary about the switch from
low-sulfur diesel (LSD) to ultra-low-sulfur
diesel (ULSD). Here’s helpful information:
BOB ADRIANCE: The most immediate
concern with ULSD — certainly the one that’s
received the most publicity — is lubricity. When
diesel fuel is refined to make ULSD, it’s reacted
with hydrogen to remove the sulfur. This process
removes much of the lubricity. (Many people mis-
takenly believe that it’s only the sulfur that sup-
plies lubricity.) Lubricity is essential in diesel fuel
to reduce friction at the diesel’s finely machined
pumps and injectors; without sufficient lubricity,
a diesel would grind itself to a premature death.
